Rubber O Rings is a circular elastomer with a disc shaped cross section. Rubber O Rings are designed to be put inside a groove and then compressed during assembly by two or more parts, creating a seal. Our Rubber O Rings can be used for static and dynamic applications. We specially provide moulded Rubber O Rings in standard or non-standard inside diameters, cross sectional thickness and shore hardness. We can also manufacture O Rings in other materials such as polyurethane and PTFE. We also offer machining specifications of cross-sectional thicknesses for different O-Rings.
