PTFE Tape x 12 metres

PTFE tape is used for sealing threaded plumbing connections. This 12m long x 12mm wide roll of PTFE tape is WRAS approved for use with potable (drinking) water.

PTFE stands for Polytetrafluoroethylene, a product accidentally discovered in 1938 by Roy Plunkett, a DuPont scientist, in New Jersey. Often it's called white tape, thread seal tape or plumber's tape,

When applying PTFE tape, you normally use 3 to 4 turns of tape, starting from the end and in the same direction as the threads.
