O-Rings and O-Ring cord
O-rings are one of the simplest and effective seals ever invented.
An o-ring is 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.
O-rings are the most commonly used machine seals, and are also used for pump shafts and hydraulic cylinders.
