Description
O ring seal 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.
Hydraulic o rings 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: the O-ring is compressed resulting in zero clearance, the O-ring material is vulcanized solid such that it is impermeable to the fluid or gas, and the O-ring material is resistant to degradation by the fluid or gas.
