Also known as thread seal tape, Teflon tape, or plumber’s tape, PTFE tape is short for polytetrafluoroethylene tape. The most standard industry term for plumber’s tape is thread seal tape or thread-sealing tape.
PTFE tape is known for its water-repellent properties and low friction. This makes it ideal for plumbing projects and ductwork. The polytetrafluoroethylene compound forms water-resistant seals when used between pipes or ducts to plug leaks, and the low friction of the tape helps keep the fitting lubricated for easy future removal.
It is also used in a wide variety of other industrial settings, and there are multiple types of PTFE tape. Depending on your project, you can choose between many different options.
