PTFE thread seal tape is wrapped around the male thread before a pipe joint is assembled. As the fittings tighten, the tape compresses between the threads to help close the small paths through which water could escape.
The tape also lubricates the threads during tightening. The white Toro and Titaseal rolls and the pink high-density Titaseal rolls have their own dimensions and specifications, listed below.
Pink Titaseal tape has a denser PTFE construction than the white Toro tapes. Each formulation has its own specifications; the pink-tape operating limits are listed separately. Rolls come on a spool with a protective cover.
