Thread seal tape (often called Teflon tape, PTFE tape, or plumbers tape) is an inexpensive polyethylene tape commonly used for thread sealing small pipe threads. Thread seal tape helps prevent against the eventuality that the threaded ends of the pipe will seize when being stripped, resulting in a leak. Thread seal tape is made with a backing made of polyethyleneethylene. The tape is most often available in white, but can be colored to match pipe thread colors (if you choose to do this).
Teflon tape is also sometimes referred to as PTFE (or PTFE tape) because it is typically used to seal threaded inserts and other threaded inserts such as drain pipes. Threads on these products are usually sealed using a threaded insert. The most common threaded inserts that use thread seal tape are drain and sewer pipes.
In order to understand how to install teflon tape correctly, it is necessary to know what it is made from. It is made of a rubber called dipstick. There are two pieces of the tape, the top layer is made of dipstick and the bottom layer is made of an acrylic-based adhesive. A layer of PTFE (or polyethylene hydrofluoric acid) will be put between the two layers to protect the adhesive and prevent it from coming apart. Then, there are six to eight microscopic rubber seals in the middle of the tape.
When thread sealant is applied to the tape, it will form a ring around the fitting or joint. This ring then rides along the joint and the rest of the tape is tapered off. The tape does not go all the way around the joint; it stops just above where the protruding fittings are. These protruding fittings are called pin joints. They have an open top so that water can flow under them, but they are not meant to be water tight.
Many plumbers think that teflon tape is not very reliable because it only has two layers. This is true, but the tape can actually seal two different sides of a fitting. The trick is that both sides must be sealed to keep out moisture. Another thing plumbers do is to apply a very thick amount of teflon tape the fitting tightly, but not to harden it. When this happens, leaks will start forming in the fittings.
To seal a Teflon fitting properly, you must make sure that the tape is very thick, and also that it is applied very tightly. Thin or flimsy tape will not seal properly, and may easily get peeled or ripped apart. A common mistake that plumbers make with tape is to try to seal a Teflon fitting with thread sealant, when the thread sealant has been weakened already. This is why you must make sure that your tape is very thick, to prevent it from weakening and becoming undone. If a leaking Teflon fitting needs to be repaired, it is important that it is fixed as soon as possible before it starts weakening and causing leaks.
