Teflon tape, also known as plumber tape or PTFE tape, is used primarily to lubricate and seal the threaded joints of pipe connections in plumbing installations to prevent water and gas leaks. When wrapped around male pipe threads, the thin polytetrafluoroethylene film fills microscopic gaps between the mating threads as they are tightened together, creating a durable barrier against high water pressure. It is commonly utilized across showerheads, pipe nipples, threaded faucet connectors, gas lines, and various plumbing valves. By reducing friction during assembly, the tape allows fittings to be tightened more securely without seizing or damaging the metal or plastic threads.
