Materials include: Viton®, Nitrile, EPDM, Silicone, Neoprene, Teflon® PTFE, Chemraz®, and Kalrez®. We maintain locations throughout the USA, Singapore and Taiwan. An O-ring, also known as a packing, or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface. The O-ring may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons.O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, and reliable and have simple mounting requirements. They can seal tens of megapascals (thousands of psi) of pressure.
  • O-rings come in a variety of sizes British Standard (BS) which are imperial sizes or metric sizes.
