black/white NBR/EPDM/silicone pipe flange rubber gasket/joint rubber ring
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.
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. They can seal tens of megapascals (thousands of psi) of pressure.
Function of the rubber o ring
O-Rings are used in sanitary pipeline systems for the Auto, Machinery, Food, Dairy, Beverage, Pharmaceutical and Bio-Tech industries.
