PTFE tape is a type of tape used by plumbers, handymen, electricians and homeowners to help prevent pipe leakage. It is a thin and stretchy tape that you wrap around the male threads of pipes before screwing them to their female counterparts. The PTFE clings to itself and the pipe, creating a seal. Depending on the job you need the tape for, you can find different types that work for different purposes. For instance, there is a plumbers tape that is colored yellow and rated for gas pipe connections. There is also skived PTFE tape that has high elongation and can conform to sharp bends.
There are two main kinds of teflon coated tape: pure PTFE tape and fiberglass tape with a PTFE coating. There are also some differences in the way they are manufactured, as these two different production techniques give the tapes different mechanical properties.
The main function of the teflon coating on the tape is that it is resistant to chemical and high temperature resistance. It can work under a wide range of temperatures from low ones (-196°C) to high ones (300°C). This makes it a good choice for many different projects, especially those with harsh chemicals.
The teflon coating also makes the tape waterproof, making it useful for plumbing repair jobs in a variety of conditions. You can use it on your kitchen or bathroom pipes to keep water leaks at bay. You can even use it in your car to seal the fuel pipes.
