O-ring Kits

System 1 has replacement O-rings for all filter assemblies made of Buna (use with oil, gasoline, methanol and E85) or Viton (use with nitromethane and diesel fuel). Please use the handy cross-reference chart to identify the proper O-ring kit through either the part number of the filter assembly or the diameter of the housing. Click on the O-ring kit part number to link to the shopping cart.
