2. Thread seal tape - Wikipedia

   en.wikipedia.org/wiki/Thread_seal_tape

   PTFE tape applied on an NPT fitting, in the direction of the threads. Thread seal tape is appropriate for use on tapered threads , where the sealing force is a wedge action. Parallel threads may not seal effectively with or without tape, as they are intended to be sealed by a gasket .

Thread seal tape Polytetrafluoroethylene (PTFE) film tape commonly used in plumbing for sealing pipe threads. Ultra-high-molecular-weight polyethylene tape

4. Polytetrafluoroethylene - Wikipedia

   en.wikipedia.org/wiki/Polytetrafluoroethylene

   Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene, and has numerous applications because it is chemically inert. [3] The commonly known brand name of PTFE-based composition is Teflon by Chemours, [4] a spin-off from DuPont, which originally invented the compound in 1938. [4]

5. Surface treatment of PTFE - Wikipedia

   en.wikipedia.org/wiki/Surface_treatment_of_PTFE

   Polytetrafluoroethylene (PTFE), better known by its trade name Teflon, has many desirable properties which make it an attractive material for numerous industries. It has good chemical resistance, a low dielectric constant, low dielectric loss, and a low coefficient of friction, making it ideal for reactor linings, circuit boards, and kitchen utensils, to name a few applications.

   This resulted in the transformation of the solid PTFE into a microporous structure that was about 70% air. The company initially referred to this new material as "fibrillated PTFE". One year later, it was given the name of "Gore-Tex expanded PTFE". [5] Today, expanded PTFE (ePTFE) accounts for the vast majority of the company's products.

7. Pipe (fluid conveyance) - Wikipedia

   en.wikipedia.org/wiki/Pipe_(fluid_conveyance)

   Steel pipe is sometimes joined using threaded connections, where tapered threads (see National Pipe Thread) are cut into the end of the tubing segment, sealant is applied in the form of thread sealing compound or thread seal tape (also known as PTFE or Teflon tape), and it is then threaded into a corresponding threaded fitting using two pipe ...
