AA Thread Seal Yellow 1/2 in. W X 260 in. L Thread Seal Tape 0.1 oz

Thread seal tape (also known as PTFE tape, Teflon tape or plumber's tape) is a polytetrafluoroethylene (PTFE) film tape commonly used in plumbing for sealing pipe threads. Thread seal tape lubricates allowing for a deeper seating of the threads and it helps prevent the threads from seizing when being unscrewed.
