Teflon tape, or PTFE tape, is a thin, flexible tape coated with polytetrafluoroethylene. Widely used in plumbing, it provides a reliable, leak-proof seal between threaded pipes and fittings. Applied by wrapping clockwise around threads, it lubricates and creates a barrier, preventing leaks and enhancing ease of assembly. While not a sealant on its own, it complements thread sealant compounds for secure connections. Ensuring clean surfaces, wrapping 2-3 layers, and securing the end properly optimizes its effectiveness. A staple in plumbing applications, Teflon tape remains a trusted solution for achieving tight, durable seals in various threaded connections.
