Cronex Thread Seal Tape is a PTFE (Teflon) film tape designed for sealing threaded pipe joints, including threaded fittings used for water, gas, and general plumbing applications. It is made for both home, commercial, and industrial uses. When applying it, you should wrap the tape around the male threaded end in the direction. Using it properly helps ensure a tight seal without over‑tightening or damaging the threads.
