Tape FUM is a film seal designed for sealing threaded, nipple and flange connections. The abbreviation FUM stands for fluoroplastic sealing material. The tape is made by rolling raw fibers of fluoroplast-4 and drying it in a vacuum chamber. It has several advantages, which are due to the material of manufacture and which allow you to seal joints under pressure, such as threads on the manifold.
Advantages
Thermal resistance. The film can be used in the range from -70 to +260 °C, which significantly expands the possible range of its application. It can be wound on pipes of cold, hot water, heating and gas.
impact resistance. Does not collapse and does not lose its properties in aggressive environments, for example, chemical - acidic and alkaline. Not subject to destruction by microorganisms. High-quality winding will last longer than flax.
Safety. The material is hardly combustible, ignites only at temperatures above +560 °C. Not explosive.
Antifriction. Reduces the friction of the connected elements and does not break the thread.
Duration of operation. Film seals last up to 13 years, which is a good indicator compared to other sealing materials.
Big choice. To date, a variety of tapes of various thicknesses and widths from different manufacturers is presented. FUM is inexpensive and available to every master.
FUM-1 is used for sealing joints on industrial and domestic engineering highways. Withstands aggressive acidic and alkaline environments, high temperatures. The film of this brand is used in chemical industries and in oil refineries, where the pipeline is designed to transport liquids and gases. The seal is also suitable for connecting summer water supply in the country. The composition contains vaseline oil as a lubricant.
FUM-2 is designed for pipelines with an oxygen environment and oxidizers. For example, when laying an oxygen pipeline together with other pipelines in covered channels in oxygen shops and gasification stations. Provides a very strong layer and withstands significant pressure. Contains no lubricant.
FUM-3 combines the purpose of the first two types of seals, as it is their edge trim. It is used in pipelines with a clean, non-aggressive medium without impurities. Contains no lubricant.
The abbreviation FUM tape is a fluoroplastic sealing material in the form of a tape. This product is used in cases where it is necessary to ensure reliable sealing of the above-mentioned connections of pipes for water and gas.
This product is made from fluoroplastic, which has the necessary plasticity and high characteristics of tightness and heat resistance. The tape is produced in the form of transparent or white strips, which are wound into compact rolls. The width of the tape varies from 1 cm to 1.6 cm, some types have an additional layer of waterproof grease or glue.
Plumbing Fum tape is marked with symbols indicating the brand, what thickness, width and length in a roll.
Let's give an example: FUM 10m x 12mm x 0.1mm, which indicates a length of 10 meters, a width of 12 millimeters, a thickness of 0.1 millimeters.
Properties and technical characteristics of fum tape
Using this product when carrying out plumbing work, it is useful to learn about the main properties, characteristics, pros and cons.
Tape fum: specifications
Plumbing tape has a fairly low level of friction, it is elastic, slips and stretches. This makes it easy to seal various connections. It provides a good fit and seal.
Fumlenta has high thermal stability (resistance to temperature extremes). This is an important property of the material, which allows it to withstand exposure to high temperatures, more than 300 C. But it should be noted that when heated above 250 degrees, the tape material begins to release toxic harmful substances.
It has high plasticity and tensile strength. The FUM sanitary tape is very durable and practically does not rot.
It has great resistance to chemicals, acids, alkalis.
These tapes can even serve to insulate electricity.
Advantages of FUM tape
The fum tape has received great demand and widespread use due to its ease of use and numerous advantages, such as:
Ease of winding and stacking;
Elasticity and high strength (it is very difficult to break);
Possibility of use for sealing metal, metal-plastic and plastic pipes for water and gas;
Long service life;
If necessary, it is very easy to dismantle and replace the seal.
It is worth adding that, when sealing with a fum-tape, additional impregnation or special mastic is not required on the winding.
The disadvantages of sealing with PTFE are minor, but you should be aware of them:
It is undesirable to use with a diameter at the joints of more than 50 mm. In this case, the thickness of the tape from 0.1 mm will not be able to reliably ensure sealing.The presence of sharp edges on the threads or joints can easily cut through the fum tape, leading to a violation of the integrity of the seal.
Important! When sealing with synthetic materials, any rotation of the plumbing fittings can lead to leakage. When disassembling the connections, the threads should be very carefully cleaned of the old coating and re-winded.
Types of tape FUM
In fact, this product is a deformable filler and at the same time a thread lubricant, thanks to them, sealing is better. Various types of FUM tape allow you to use it in almost all piping systems, you can order with delivery in the online store here. (And don't forget about cashback up to 90 percent).
The tape is divided into types according to another criterion - dimensions. Manufacturers produce products of various thicknesses, widths and lengths. The minimum thickness is 0.075mm and the maximum is 0.25mm. The width starts from ten millimeters. Length from 10 meters (100 cm).
You can buy a special tape designed for gas pipes, it has a yellow color. It is she who has a maximum thickness of 0.25 mm. This tape, its purpose is to create a tightness of the gas supply system operating under low pressure.
Which is better: tow or fum tape
Each material has its advantages and disadvantages. Flax (tow) is mainly used for sealing joints of steel pipes and those with a large diameter.
Benefits of tow (flax):
Threads of fibers are resistant to mechanical stress;
During installation, adjustment of the connection and the possibility of unscrewing by 45 degrees are allowed;
Creates a tight connection;
The ability to use linen tow on joints with a large diameter, from 50 mm.
The main disadvantage inherent in all natural materials is the susceptibility to decay under the influence of moisture. Requires periodic inspection and replacement.
It is convenient to use plumbing tape on pipes of small diameter, plastic pipes, in case of using thin-walled fittings. It is easier to work with fum tape, installation takes less time.
Answering the question "Which is better - fum tape or sanitary flax?" cannot be answered unambiguously. It all depends on the type of plumbing work, pipe material and the purpose of the system. For example, if you need to connect a flexible hose to a mixer in the kitchen, it is more practical to use fum tape, and it is better to seal the fitting on a water pipe with tow (flax).
Definition of fum tape
The full name of the fumlent is a fluoroplastic sealing tape. This is a product that is used to seal the various connections mentioned above.
Production and varieties
Production is carried out using a fluoroplastic bundle. The film is rolled out to a certain thickness. After all, the sealing material is sold as a tape in various sizes. The tape itself is wound on a reel. I use the product during the installation of structures that are under a certain pressure. These structures are water supply, gas supply or central heating system.
The product is a deformable filler, as well as a thread lubricant - thanks to this, sealing is better. This product is practically not used in systems that are responsible for heating on hot water. However, due to such sealing, heat is retained.
This tape is also divided into types according to another criterion - size. Thickness, width and length are different. The thickness can start from 0.075 and reach up to 0.25 millimeters. The initial width is ten millimeters. The length starts from one hundred centimeters.
You can also find a specially designed gas tape on store shelves, which is yellow. 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 also use an ordinary fum tape.
Properties and characteristics of sanitary tape
Let's talk about the main properties and characteristics of this product. Tape fum specifications:
The fumlent has a low level of friction. The tapes are slippery, which makes it easy to seal various joints. Fum tape improves fit and seal.
Plumbing tape has a high level of heat resistance (resistance to different temperatures). This suggests that this material is able to withstand high temperatures - more than 300 degrees Celsius. However, they can be used at a temperature of 250 degrees Celsius and no more. Since at higher temperatures toxic substances are formed that can harm the human body. The tapes are also excellent electrical insulators.
The product has excellent strength and ductility. The material has a high level of resistance to alkalis and acids. The tape is quite inert to various chemicals. Also, sanitary tape has a huge resistance to gndeniya.
There is inertness to chemical and biological substances. Shows resistance to alkalis and acids.
These are the characteristics of this product.
Before this sealing material appeared on the construction market, tow for plumbing was used for this procedure. Plumbing tow is flax fibers. 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 for sealing a variety of joints. However, instead of oil paint, a special sealing paste is used, which is applied from the top of the winding. Specially designed sealing paste gives the system strength, reliability and durability.
Thanks to this sealing substance, a reliable protection against rotting of the structure is formed. Previously, sanitary tow with the additional use of oil paint was difficult to dismantle, thanks to the paste, this can be done easily if necessary.
