Thread seal tape is a polytetrafluoroethylene (PTFE) film used in sealing pipe threads. It is also known by the trade name Teflon tape. thread seal tape lubricates allowing for a deeper seating and tightening of the threads, helping to prevent the threads from seizing when being unscrewed. The tape also works as a deformable filler and thread lubricant, helping to seal the joint without hardening or making it more difficult to tighten, and making it easier to tighten. The tape is typically wrapped around a pipe’s thread three times before it is screwed into place and is commonly used commercially in applications including pressurized water systems, central heating systems, and air compression equipment.
They are composed of white sintered PTFE and are wound on a blue spool with a white snap-on shell cover. These PTFE film products are recommended for use on all threaded fittings for the passage of water, gas, oxygen, chemicals, and other fluids or gases.
