O-Rings

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. Static applications of o-rings may include fluid or gas sealing applications in which: (1) the o-ring is compressed resulting in zero clearance, (2) the o-ring material is vulcanised solid such that it is impermeable to the fluid or gas, and (3) the o-ring material is resistant to degradation by the fluid or gas. o-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, reliable and have simple mounting requirements.
