Teflon Tape 1/2" (also known as PTFE tape or plumber’s tape) is a thin, flexible tape used for sealing pipe threads to prevent leaks in plumbing and gas connections. It provides a watertight seal, reduces friction between threads, and makes disassembly easier. Commonly used in water pipes, gas fittings, and air compressor lines, it is an essential item for plumbing installations and repairs.
