PTFE Envelope Tri-Clamp Gaskets are the only choice when needing extreme chemical resistance and temperature range. These gaskets are extremely unique in their construction because they have a Viton filler for compressibility surrounded by an 'Envelope' of PTFE which creates a unique combination of chemical resistance while providing an exceptional sealing characteristic. Normal solid PTFE gaskets are very tough to seal on their own and are usually not recommended in vacuum applications due to the gasket being very rigid because PTFE is not very compressible by itself.  Tri-Clamp/ Tri-Clover Sanitary Fittings Gaskets create a pressure-tight seam between multiple stationary components, relying on a compression seal to prevent unwanted gas or liquid emissions.
