O-Rings

O-Rings are a common type of rubber seal with a circular cross-section. Through compressive deformation, they fill assembly gaps to seal liquids, gases, and lubricating media, making them one of the most widely used static sealing products in industrial equipment.

We offer O-Rings in a variety of materials, including NBR (nitrile) rubber O-Rings, Silicone O-Rings (VMQ), FKM (fluororubber) O-Rings, EPDM O-Rings, HNBR (hydrogenated nitrile) O-Rings, and PU (polyurethane) O-Rings, allowing the right material to be selected according to different operating temperatures, contact media, pressure ratings, and installation structures.

O-Rings made from different materials each offer their own performance advantages: NBR O-Rings have good oil resistance and are suitable for general industrial sealing, hydraulic systems and pneumatic equipment; Silicone O-Rings are heat-resistant and meet hygiene requirements, making them suitable for food, medical and bathroom equipment; FKM O-Rings resist oil and acid/alkali attack, making them suitable for chemical environments and automotive fuel system sealing; EPDM O-Rings resist water and steam, making them suitable for outdoor engineering and automotive cooling systems; HNBR O-Rings resist high pressure and wear, making them suitable for construction machinery equipment; PU O-Rings resist wear and high pressure, making them suitable for hydraulic cylinders and heavy-duty equipment.

O-Rings are widely used in hydraulic equipment, pneumatic systems, machinery manufacturing, the automotive industry, chemical equipment, food machinery, and medical equipment, among other industries. We support standard-size supply as well as non-standard custom processing, and can match rubber sealing rings to the appropriate specifications according to customer equipment parameters.
