PTFE Gaskets: Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. It is also known by the common trade name Teflon®, which is trademarked by DuPont. PTFE can be modified for use as a gasketing material with strong chemical resistance properties.

Full Gaskets: ​A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. Gaskets allow for “less-than-perfect” mating surfaces on machine parts where they can fill irregularities.
