The OR-SEAL gasket, usually called O-Ring, is a sealing, toroidal-shaped element with circular section. OR gasket is used as dynamic or static seal and it is usually placed in a hollow, machine-tooled seat with rectangular section.
O-Rings are widely used in all industrial sectors since elastomer materials allow the contact with a large number of fluids. Dimensional characteristics of O-Rings are defined by internal diameter and section.
