Expanded PTFE Joint Sealant

Made in the USA

TFCO expanded PTFE joint sealant is a soft, compressible gasket material made of 100% pure, expanded PTFE. It is a form-in-place gasket that conforms to almost any sealing surface. Upon compression, it forms a thin, hard ribbon that fills in surface irregularities and creates an extremely tight seal. It is capable of withstanding a wider range of pressures, temperatures and chemical environments than any other soft gasket.

Our joint sealant can be used in just about any accessible bolted joint that features a flat or serrated sealing surface. It is also easy to install and remove, making it a highly versatile and cost-effective solution for many demanding sealing applications.


  • Form-In-Place - conforms to any surface, including rough, pitted, scratched and damaged surfaces.

  • Flexible – can be installed on round, oval, rectangular and complex surfaces.

  • Chemically Resistant – made of 100% PTFE; compatible with almost any process fluid (except molten alkalis and elemental fluorine)
