Filter Parts & Gasket


Which Gasket Should I Use?

Buna

Also known as Nitrile or Buna-N, is probably the most common gasket material and it is the standard material for petroleum oils.  Buna can stand temperatures to 90°C / 200°F . Buna resists aging very well.  Not recommended for bio-diesel in concentrations over B20 (20% bio-diesel).  Heating oil applications will require gaskets that carry an agency listing: UL, ETL, Intertek, ULC or CUL.  All General Filters Buna-N Gaskets carry an ETL agency listing.

Vellumoid

Vellumoid is a treated cellulose fiber impregnated with protein glue and glycerin binder. It is used for specialty chemicals. Temperature up to 120°C / 250°F.  Not recommended for petroleum oils.

FKM BioGasket

Also known as FKM, Type 1 Fluroelastomer or Viton™ (DuPont Performance Elastomers L.L.C.). The BioGasket™ provides excellent  resistance to petroleum oils, inorganic acids, organic acids, fuel hydrocarbons, animal and vegetable oils, mineral oils and solvents.  BioGasket™ also has excellent heat resistance, making service temperatures nearing 150°C / 300°F possible.  The General Filters BioGasket™ is ETL Listed for all fuel oils and
