PTFE Envelope Gasket

PTFE Envelope Sanitary Tri-Clamp Gaskets are the only choice if you require extreme chemical resistance and temperature range. Their unique construction, with a Viton filler for compressibility surrounded by an 'Envelope' of PTFE, creates a powerful combination of chemical resistance while still sealing very well. Normal solid PTFE gaskets are very tough to seal on their own. Since PTFE is not especially compressible by itself, these rigid gaskets are usually not recommended in vacuum applications. With a wide range of sizes from 1.5” to 12” = Corrected 0.5” to 2000 mm, we’ve got you covered for whatever application you require.

PTFE Envelope Gasket Advantages

  • Excellent resistance to almost all chemicals
  • Excellent Temperature Range
  • No Chemical Leaching
  • Exceptional flexibility &Uniting the flexibility of an elastomer w/ the chemical resistance of PTFE
  • Excellent Cleanability due to PTFE (Teflon) Envelope
