Scarf Cut & Vulcanised O Rings are an excellent alternative when standard O-rings cannot be used. Scarf cut and joined O-rings are made from extruded O-ring cord, then vulcanised to form an O-ring size (ID) required. This process to join the ring has strict quality control procedures to ensure the join is at least 90% of the strength of the O-ring cord. Abbey Seals supplies a variety of sizes from 1.78mm – 25.4mm. Some limitations apply from a size perspective when smaller IDs are required and these can be checked from the spec sheet.
