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.
AMSTAR PTFE thread seal tapes meet MIL spec 27730A and are 3.5 mils
thick. They are composed of white sintered PTFE and are wound on a blue spool
with a white snap-on shell cover. Can-Do stocks PTFE thread seal
tapes that are manufactured and imported from the Far East, but domestic
products are also popular. These PTFE film products are recommended
for use on all threaded fittings for passage of water, gas, oxygen, chemicals,
and other fluids or gases.
