Gaskets

BUNA-N Tri-Clamp Gaskets Buna-N Tri-Clamp gaskets are the preferred choice of material when using a closed loop, closed column, or open blast extraction when butane or propane are used as the extraction solvent. Buna-N Gaskets offer a lower temperature rating and have better physical properties than Viton gaskets; the best part is that they cost less than Viton and provide the same chemical resistance to butane and propane. Note: BUNA-N is not recommended for use with certain alcohols   Key Features: Lower temperature range Lower costs Better compressibility and springiness Excellent resistance to butane and propane Better tear resistance Better abrasion resistance.

Silicone Tri-Clamp/ Tri Clover Gaskets Silicone Tri-Clamp Gaskets are intended to be used when using alcohol as an extraction solvent instead of butane or propane. Silicone has an excellent chemical resistance to alcohols and is the preferred gasket material when using Jacketed Reactors or Tri-Clamp Buchner funnels for post-processing winterization because they have very low extractable characteristics. Silicone gaskets also offer a very good temperature range and will retain their original shape even when compressed for a long duration. ***Note: Silicone is not recommended for use with butane or propane solvents. Key Features: Excellent resistance to Alcohols Excellent Temperature Range Excellent Rebound and Memory Very Low extractable characteristics Sizes Available: 1.5" 2" 3" 4" 6" 10" Easy On - Flanged 12" Easy On - Flanged Specifications: Material Silicone Color White Connection Type Tri-Clamp Conformance USP Class VI, FDA and 3A Compliance Thermal Properties: -Low Temperature Range -58°F -Minimum Continous Use (Static) -40°F -Brittle Point -58°F -High Temperature Range +446°F -Maximum for Continous Use (Static) +446°F Durometer or Hardness Range 65 Shore A Abrasion Resistance Excellent Tear Resistance Excellent Compression Resistance Excellent Chemical Compatibility: Butane D - Poor Propane (liquified) D - Poor Alcohols: -Amyl D - Poor -Benzyl N/A -Butyl B - Good -Diacetone D - Poor -Ethyl B - Good -Hexyl B - Good -Isobutyl A - Excellent -Isopropyl A - Excellent -Methyl A - Excellent -Octyl B - Good -Propyl A - Excellent   Disclaimer: Best Value Vacs Recommends no more than a -40F Operating Temperature and is not responsible for the user running their system with incompatible chemicals.

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. Key Features: Excellent resistance to almost all chemicals Excellent Temperature Range Excellent Cleanability due to PTFE (Teflon) Envelope No Chemical Leaching Sizes Available: 1.5" 2" 3" 4" 6" 8" 10" 12"   Chemical Compatibility: Material PTFE(Teflon)/Viton Filler(FKM) Color White/Black Connection Type Tri-Clamp Conformance U.S.P.

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.
