Expanded PTFE Joint Sealant
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.
