What Is Teflon Tape Used For in Plumbing? A Guide to PTFE Tape
While many associate Teflon with nonstick cookware, in plumbing it’s known as Teflon tape, or PTFE tape. This non-adhesive, stretchy tape is wrapped around male pipe threads to improve sealing and ease of installation. Wondering how to use Teflon tape? Simply wrap it clockwise around the threads before connecting the fitting. It serves two purposes: it seals microgaps to prevent leaks and lubricates threads for easier tightening and disassembly. Standard PTFE tape for plumbing works on copper, PVC, plastic, or steel pipes. Compared to liquid sealants, like pipe dope, Teflon tape is cleaner and quicker. Whether you’re working on water lines or fittings, this pipe thread sealant is an essential tool in any plumber’s kit.
