    en.wikipedia.org/wiki/Thread_seal_tape

    Thread seal tape (also known as PTFE tape, Teflon tape, or plumber's tape) is a polytetrafluoroethylene (PTFE) film tape commonly used in plumbing for sealing pipe threads. The tape is sold cut to specific widths and wound on a spool, making it easy to wind around pipe threads. Thread seal tape lubricates, allowing for a deeper seating of the ...

    Polytetrafluoroethylene. Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene, and has numerous applications because it is chemically inert. The commonly known brand name of PTFE-based composition is Teflon by Chemours, [1] a spin-off from DuPont, which originally discovered the compound in 1938.

    National Pipe Taper Fuel (NPTF, also called Dryseal American National Standard Taper Pipe Thread, defined by ASME B1.20.3) is designed to provide a more leak-free seal without the use of PTFE tape (often referred to by the popular brand name "Teflon") or another sealant compound.

  7. Tetrafluoroethylene - Wikipedia

    en.wikipedia.org/wiki/Tetrafluoroethylene

    Tetrafluoroethylene (TFE) is a fluorocarbon with the chemical formula C 2 F 4. It is the simplest perfluorinated alkene. This gaseous species is used primarily in the industrial preparation of fluoropolymers. It was first reported as "dicarbon tetrafluoride" in 1890. [2]
