Installation of any pipeline involves the use of a sealant. Along with traditional tow, modern material is used to make threaded, flanged and nipple joints leakproof, a universal fluorine-containing film. Fum tape, fumka, plumbing tape, teflon - the main names of the sealant for thread. Consider the technical characteristics, the pros and cons of the material, compare it with linen tow.
The modern gasket replaced the tow, but did not displace it
Plumbing tape: manufacture and types ↑
Fluoroplastic sealing material or abbreviated fum tape is a polytetrafluoroethylene film used to seal a pipe joint. It is made by rolling the fluoroplastic tow to the required thickness. The sealant is produced in the form of a tape of a certain size wound around a coil (similar to electrical tape). Used in the installation of systems under pressure: water supply, gas supply, central heating. The material performs the function of a deformable filler and at the same time a thread lubricant, which improves the sealing of joints.
- fum-1 - is intended for sealing pipelines working with aggressive environments. Contains lubricant - refined petroleum jelly,
- fum-2 - used in systems in contact with strong oxidizing agents, therefore not impregnated with grease,
- fum-3 - used in systems working with clean environments. Does not contain grease.
The sanitaryware tape fum also varies in size: thickness ranges from 0.075 to 0.25 mm, width starts from 10 mm, length from 1000 mm.
Issue a special gas fum tape yellow in the thickness of 0.15-0.25 mm. For gas pipes operating under low pressure, the use of ordinary sanitary tape is allowed.
Technical characteristics and properties of the tape fum ↑
The main properties of PTFE:
- Low coefficient of friction. Fluorinated plastic polymers (PTFE) have a very low coefficient of friction - they are slippery, which facilitates the connection of fittings. Perform the role of a kind of pipe threading, improving fit and sealing.
- Heat resistance. PTFE have an extremely high melting point for plastic - 327 degrees. They are designed for use at temperatures up to 260 degrees (when heated above emit toxic fluoride compounds). PTFE - excellent dielectrics (electrical insulators), which is an additional plus.
- Plasticity and strength. Resistant to mechanical stress. They work at constant pressure up to 10 MPa, withstand drops up to 41 MPa. Average life is 13 years. Prolonged exposure to light slightly affects the properties.
- Chemical and biological inertness. They are highly resistant to acids and alkalis. No solvent for PTFE yet. The polymers are as if uniformly sheathed with fluorine atoms, which makes the material inert with respect to almost all chemicals. Decomposition is possible only in extreme conditions created in special laboratories. Not subject to decay.
Pavel: what is it and how to work with it ↑
Before fum tapes appeared on the market, a plumbing fixture consisting of flax fibers was used to seal threaded pipe joints. Optimum results were achieved by smearing a layer of tow wound on the thread with a small amount of oil paint. After several years, such a compound was difficult to disassemble.
Now sanitary linen in the form of long silky threads is used along with new sealing materials. Only now a layer of sealing paste is applied over the winding, providing a reliable and durable connection. The paste protects the flax from decay, and if necessary facilitates dismantling.
How to wind a tow on a thread ↑
To prevent the flax from slipping over the thread, notches are provided on it.
Please note: in the absence of factory notches, they should be applied independently, otherwise, when screwing on the fitting, the flax will run off the thread.
For winding, a small strand of flax is separated. The length and thickness of the "lock" is determined visually depending on the diameter of the pipe. The winding is done as tightly as possible, the threads are directed along the thread, the free end of the tow is fixed with a finger, and after a couple of turns it is brought into the guide strand. The tightness of the joints provides the optimum layer thickness. It is quite difficult to calculate the density: you need experience, a certain "plumbing" eye.
How to wind the tape fum on the thread ↑
The tape is wound onto the external thread of the fitting. When repairing plumbing, the old connection must be cleaned of rust, dirt, and then degrease the surface with a solvent. Winding is done only after drying. The main requirement: the fum tape should be pulled quite strongly so that it fills the grooves and fits the thread tightly. Experienced plumbers say tape breaks are better than loose windings. The number of layers varies from 4–6 to 20–25 and depends on the thickness, width of the tape and the diameter of the pipe - the main thing is that all the threads are hidden. Plumbing tape requires a little more than tow, because unlike flax, it will sit. When working with fittings of Ø 1 inch or more, it is more convenient to wind the cigarette holder the whole width, making sure that it is pressed into turns. After tightening the fiber nut, the fum tape is broken into threads filling the inter-turn space - the seal remains in the thread and seals it.
Important: adjustment (adjustment) is not possible without loss of tightness - you cannot even slightly unscrew the twisted fitting.
Which is better: tow or tape fum ↑
Each material has its advantages and disadvantages. Plumbing flax is used to seal joints of steel pipes (especially rusty and / or large diameters).
- the ability to adjust the connection: permissible unscrew back 45 degrees,
- reliable tightness: absorbs moisture well,
- resistance to mechanical stress,
- easy dismantling of the connection.
The disadvantage is the tendency to rot / decompose, since tow refers to natural materials.
Plumbing tape is preferably used on pipes of small diameter, plastic pipes, in the case of thin-walled fittings. It is easier to work with fum tape, less installation time.
To the question: “Which is better - fum tape or sanitary flax” there is no definite answer. It all depends on the specific plumbing work. Let's say it’s more convenient to connect the kitchen faucet with a flexible hose using fum tape, and it is better to seal the fitting on the water pipe with tow.
Anaerobic Sealant Gels: Santechgel ↑
Another modern material for sealing pipe threads is santechgel. Reliable compaction is due to the polymer component of the gel. After hardening, Santechgel does not shrink or expand, it is resistant to temperature changes (from -60 to +150) and pressure surges, it has proven itself in various environments: water, natural and liquefied gas, heating antifreezes.
There are three types of Santechgel:
- In green tubes - lightweight dismantling.
- In blue - medium dismantling.
- In reds (Stop Master Gel) - dismantling with heating.
Installation using santechgel is simple: shake the tube and apply the gel with a thick layer over the entire circumference of the thread, distribute evenly (with a brush, a special spatula), perform assembly of the structure. Excess gel is removed with a rag. Gel polymerization takes 15–20 minutes.
Important: Santechgel should be applied only on a clean, fat-free surface.
Application features
The product is characterized by water-repellent properties, the material easily takes the form of a working base, which greatly facilitates its operation and installation. The tape has high elasticity even at low temperatures, the material prevents the development and reproduction of harmful microorganisms, and also does not lose its properties during contact with aggressive chemical compounds. The environmental friendliness of the product allows you to use it both outdoors and indoors.
The composition of the elements that make up the tape includes several materials.
- The basis of rubber or bitumen with adhesive. These components provide the product with water resistance and are responsible for fixing and sealing the work surface.
- High strength aluminum foil layer. It provides the tape product with tear resistance.
- A special film edge layer that is removed before the tape is fixed to the surface.
The presence of the above components allows you to perform high-quality sealing of seams and joints in any design made from a wide variety of materials. Based on the area of use, self-adhesive sealant can be supplemented with layers of other raw materials. Most often, such measures are resorted to to increase any product properties.
Taking into account the scope of use, adhesive sealing tapes are classified as follows:
- single-sided products,
- bilateral products.
In the latter case, the material has a working surface on both sides.
In addition, the products are divided into several types.
Butylene tape
This product is a universal product made on a butyl rubber basis. During production, such products are coated with a thin sheet of aluminum. The adhesive layer has a silicone-based protective film. The main component of the product is considered to be an excellent composition for insulation, in addition, it is used as a protective material for such raw materials as wood, plastic or metal. Bilateral products are compatible with most PVC materials due to the chemical inertness of butylene. Products are recommended for use in different temperature conditions, the products are resistant to negative temperatures. The operating temperature range is from + 120C to -60C. The tape is odorless.
The metal layer that the tape has provides it with resistance to ultraviolet, alkali and various acids. Butylene elastic products are produced 10 meters long, the width of the goods on the market is from 5 cm to 30 cm with a thickness of up to 1 mm.
The product is recommended for external and internal work with wood, polycarbonate, PVC systems, concrete and others.
Usage Tips
To make a reliable and high-quality connection with sealing tapes, it is worth following the general recommendations for the installation of products.
- First of all, you need to take care of the cleanliness of the working area - you need to work with a clean and fat-free surface.
- Experts recommend treating the junction with a waterproofing substance, and then stick the tape on the wet composition.
- The material is firmly pressed to the surface with a spatula to let out all the air.
- The corner joints of the elements must be isolated with a spacing.

Previously, gypsum, tow, homemade putties, clay, which did not last long, were used for this purpose. Now such materials have been replaced by tape sealant or sealing tape - a multifunctional product based on polymer compositions. Sealing tapes have a wide range of operation: they are in demand not only in the residential sector, but also in industrial facilities, communications. The need for sealing is due to the risk of moisture penetrating into the cracks of structures, which will inevitably lead not only to a violation of the microclimate, but also to rapid destruction of the base. A sealing tape prevents these effects by reliably isolating the seams from water, dust, and dirt. The main advantage of the tape over other sealants is its ability to self-adhesive on the base, for which you only need to tear off the edge film layer. Sealing does not require the purchase of special tools, pasting the seams with masking tape, and the work of applying tape is minimal labor and is easy even for a beginner. The tape has a uniform elastic surface, while inside it is reinforced with a layer of aluminum foil or other durable materials. The characteristics of the sealing agent are as follows:
Varieties of sealant tapeDepending on the number of adhesive sides of the tape can be one-sided and two-sided. By field of operation, the products are divided into:
Butylene tapeSuch sealants are made on a butyl rubber basis, they are classified as universal. The tape provides high-quality insulation protection, protects metal, wood, polycarbonate, concrete from damage. It does not harm PVC and other types of plastic due to the chemical inertness of butylene. The aluminum layer of the tape provides resistance to the effects of acids, alkalis, ultraviolet radiation. Other properties and characteristics of this type of sealant are as follows:
Bitumen-polymer tapeSuch tapes provide corrosion and dielectric protection of structures. Due to moisture resistance, they can be used for insulation of underground pipelines, water supply systems, sewers, for roofing. The material easily repeats the shape of any surfaces, including those with irregularities. With gusts and cuts, the bitumen-polymer tape is able to self-seal, while maintaining reliable joint protection. Polycarbonate TapeIt is also called a "swelling cord." It is implemented in two forms - with a round and square section. The material is made from a special hydrophilic rubber, so it is able to increase by 6 times in size after contact with water. Polycarbonate tape has the following properties:
Scope of applicationSealant tape can be used to seal joints and joints of almost any building structures made of homogeneous or dissimilar materials. With its help produce:
Tape manufacturersOn sale there are a large number of sealant tapes, differing in base, size. Here is a list of the most popular brands:
Also in stores you can find tapes of brands "Abris", "Liplent", "Guerlain", "Masterflex", "Comfort". Tips & TricksBefore applying tape, you need to take care of the cleanliness of the working area. Degrease the surface, remove all dirt, dust, old paint, wipe off traces of oils and oil products. The coating bordering the seam is treated on both sides with a special waterproofing compound. Further, the procedure is as follows:
Sealant tape provides reliable insulation of any joints and joints. Its use will help protect buildings and structures from pollution and moisture and increase the period of their maintenance-free service. Production and varietiesManufacturing is carried out using a PTFE tow. The film is rolled to a certain thickness. In the end, the sealing material is sold in the form of tapes of various sizes. The tape itself is wound on a spool. I use the product while mounting structures that are under a certain pressure. These designs are water supply, gas supply or a central heating system. The product is a deformable filler, as well as a thread lubricant - this makes sealing better. This product is practically not used in systems that are responsible for heating on hot water. However, due to this sealing, heat is retained. Consider the varieties of this product:
This tape is also divided into types according to another criterion - dimensions. There are different thickness, width and length. Thickness can start from 0.075 and reaches up to 0.25 millimeters. The initial width is ten millimeters. The length starts with a hundred centimeters. You can also find on the shelves of stores specially designed gas tape, which has a yellow color. The maximum thickness of this material is 0.25 millimeters. This tape is intended for gas supply - a system that operates under low pressure. But for gas supply, you can apply the usual fum tape. Properties and characteristics of sanitary tapeLet's talk about the main properties and characteristics of this product. Tape fum specifications:
These are the characteristics of this product. Before this material for sealing appeared on the construction market, tow was used for this procedure for plumbing. Plumbing tow is a flax fiber. However, it was necessary to additionally use oil paint for sealing. Oil paint was used for lubrication. Plumbing flax fibers are also used today along with other products to seal a variety of compounds. However, instead of oil paint, they use a special paste for sealing, which is applied from the top of the winder. Specially designed sealing paste gives the system strength, reliability and durability. Thanks to this sealing substance, reliable protection against rotting of the structure is formed. Previously, a plumbing fixture with the additional use of oil paint was difficult to dismantle, thanks to the paste it can be done easily if necessary. The method of winding plumbing towIn order to prevent the flax from slipping over the thread, notches are made on it.
Before wrapping, it is necessary to separate a small strand of flax. Determining the length and thickness depends on the diameter that a gas, water pipe has. Winding must be tight. The fibers are wound in the direction of the thread. And the end of the plumbing tow, which turned out to be free, must be fixed with a finger. Sealing tapes for the inner and outer seamSealing tape Ease of use and durability. Metallized and diffusion tapes used in repair and construction works forsealing roofing, attic windows and engineering communications. This product has a fairly wide scope, tapes are used to pair concrete, wood and metal joints. It is also used for vapor barrier and effective sealing of gutters. Metallizedsealingtape It has an adhesive base, it is universal in application and very durable. From below, a protective film is applied to the tape, which is easily removed during installation. Among the features of sealing tapes are the following: - the possibility of fireless installation, - reliable adhesive layer, - special equipment is not required for laying, - the material can be used in any climatic zone. Increasingly, in the manufacture and installation of double-glazed windows are used window tapes. This technology was invented in Western countries, from where it came to our market. Using tapes makes it possible to improve thermal insulation and prevent moisture from entering the room. In the cold season, due to the low temperature outside, condensation begins to appear on the inside of the glass packet around the window. If the temperature drops to too low, this can lead to the formation of frost or frost. This is especially noticeable at the bottom of the window. The best solution is to use special tapes. Nowadays, in industrial goods stores there is a large assortment of these products. This window tape It is often used in the manufacture of double-glazed windows. Its main advantage is that it is able to successfully replace with itself a sealant, a desiccant and a remote frame. It is characterized by efficiency and has high technological qualities. The use of tape sealing type has several advantages:
Using the tape is very simple: you just need to put it on one glass, and then combine it with the second and send the structure to the press. The action of assembling a double-glazed window takes no more than a minute, and the service life is measured for decades. To buy a sealing tape You can in the store of industrial goods, and its cost is available to everyone. Other types of tapes Among other types of tapes, it is very popular. metallized tape for windows. It is used at the internal joint in the place where the window unit adjoins the wall opening after the foaming process. As a result, the joints of window openings on the inside become airtight. Part tapes Airtight foil and nonwoven fabric included. Vapor barrier tapemetallizedof type It is distinguished by its ductility, anti-diffusion, and the ability to use it on both sides (however, it has only one side self-adhesive). Tape easy to clean, colorable. It has good water and air tightness. It is worth paying attention to such products as diffusion type tape. It has excellent moisture-proofing properties and is vapor permeable. It is based on a non-woven material belonging to the membrane type, which is produced from synthetics. The main purpose of such a tape is to waterproof the lower seam remaining after installation, as well as other seams and joints of the double-glazed window. Diffusion tape perfectly protects the structure from moisture. Often diffusion tape It has two adhesive strips on one side (it is much less common to find an option when both sides are glued). For one strip, the tape is attached to a translucent structure, for another - to a slope or wall. Since this type of tape has a wide variety of sizes, you can choose a product to protect any seams. In addition, the use of these tapes helps to protect the mounting foam from moisture from the outside, to remove existing moisture from the foam, thus ventilating the joint. Glue strips are characterized by high strength, surpassing in their performance standard requirements of GOST. This mounting tape, price which is democratic in industrial goods stores, does not require the use of special tools during installation. It is enough to remove dirt from the surface of the seams and the joint and stick the tape as tightly as possible, since rain moisture will start to get into any gaps and crevices. Butyl tape part is found in the assortment of shops. Differs in a variety of types, well protects from steam and moisture. Often has a double-sided work surface. It features easy installation, good grip. If you need high quality tapes for windows, price in our store will pleasantly surprise you.
