O Rings

black o rings

O rings are one of the simplest and effective seals ever invented: a loop of elastomer, with an o-shaped cross-section.

O-rings are commonly made from viton, silicone, nitrile, and neoprene; and are available in metric and standard sizes. O-rings are specified by the inside diameter and the cross section diameter (thickness). The UK standards sizes are known as BS Sizes, and range from BS001 to BS932.

They are the most commonly used machine seals, and are also used for pump shafts and hydraulic cylinders.
