    PTFE Envelope Tri-Clamp Gaskets with Viton Filler - USA Made

    PTFE Envelope Tri-Clamp/Tri-Clover Gaskets with Viton Filler 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. ***Note: Best Value Vacs ONLY recommends the use of PTFE Envelope gaskets with High Pressure clamps to ensure a positive seal on the system.

  • Tef-Flex PTFE / EPDM Unitized Sanitary Tri-Clamp Gasket

    Tef-Flex PTFE / EPDM Unitized Sanitary Tri-Clamp Gasket

    Tef-Flex Sanitary Tri-Clamp Gasket Tef-Flex: A Tef-Flex sanitary gasket’s contact surface is a layer of PTFE grafted to an EPDM rubber inner core. This totally bonded construction provides an exceptionally pure and incredibly flexible seal. By grafting the elastomer with a layer of PTFE, Tef-Flex will behave like an elastomer but will prevent product contamination, service interruptions and clean-up costs associated with traditional elastomer seals. The PTFE grafted elastomer in a Tef-Flex sanitary gasket will maintain I.D. without re-torquing or leaking. Key Features: Excellent resistance to almost all chemicals Excellent Temperature Range Excellent Cleanability due to PTFE (Teflon)  Excellent Flexibility Sizes Available: 0.5" 0.75" 1" 1.5" 2" 2.5" 3" 4" 6" 8" 10" 12" Chemical Compatibility: Butane A - Excellent Propane (liquified) A - Excellent Alcohols: Amyl A - Excellent Benzyl A - Excellent Butyl A - Excellent Diacetone A - Excellent Ethyl A - Excellent Hexyl A - Excellent Isobutyl A - Excellent Isopropyl A - Excellent Methyl A - Excellent Octyl A - Excellent Propyl A - Excellent Disclaimer: BVV Recommends no more than a -40F Operating Temperature and is not responsible for the user running their system with incompatible chemicals.
