Product Name: Rubber O Rings for industrial pumps seals


O-ring is a mechanical gasket in the shape of a torus.It’s 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.

O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, and reliable and have simple mounting requirements.They can seal tens of megapascals of pressure.

O-ring selection is based on chemical compatibility, application temperature, sealing pressure, lubrication requirements, durometer, size and cost.
