Fuma Tape is a PTFE thread sealing material that is a green film produced by rolling a tow. In appearance, the product is a snow-white flexible tape designed to seal the threads of pipeline connections.
The material can be used in any conditions: at temperatures from minus 60 to plus 200 degrees Celsius and pressure up to 10 MPa. In some cases, it is permissible to use a product for fittings that operate at a pressure of 40 MPa.
Depending on the operating conditions, there are three brands of tape.
The first is produced in two varieties. It is used to seal systems working with general industrial media, with structures through which concentrated and dilute acids and alkalis move. This Fuma tape contains vaseline oil lubricant.
The second grade is designed to seal systems that work with strong oxidizing agents and solutions.
The third one also withstands the impact of an aggressive environment andrepresents the edge parts of the tape of the first two brands, as well as a special SKL film.
In addition to the options described, Fuma tape is produced, which is intended for retail. It is also used in everyday life.
There are rules for working with the material. Before installing the fittings that need to be sealed, the threads must be thoroughly cleaned of rust and dirt. You can use gasoline for this. Fum-tape or tow should be wound on the thread of the plug or valve along the thread from the beginning. In this case, each subsequent turn should partially overlap the previous part of the material. To prevent the formation of folds and wrinkles that roll up when the plug is screwed in and lead to loose connections, the tape should be wound with a stretch.
To facilitate the work, it is necessary to use the material together with the roll, which is pressed against the threaded part, moving around the circumference. After winding is completed, the tape must be pressed against the thread with force, scrolling a little with your fingers. After creating the seal, you can start screwing parts, for example, a tap. This should happen with effort, the Fuma tape (or tow) is kneaded and occupies the entire space between the threads of both components of the structure.
If the plumbing fittings are twisted too easily, then the tape should be wound up until the screwing will not occur with force. In this case, the material should slightly squeeze out at the junction of the pipe and the valve. When everything is done, you should open the water andsee if there are any leaks.
Fum-tape for gas is also produced, which allows sealing this type of connection.
The advantage of the material is its elasticity. Fuma tape is not subject to destruction, does not allow corrosion to form on the fastened parts. If you need to change something in the plumbing, disassembling the parts will not be difficult, which is difficult to say about seals based on linen or tow.
