Product Name: O Type rubber parts for mechanical seal


O-Ring Seals help to protect and seal against fluids/liquids and gas loss.  O-rings are designed for both static and dynamic applications. The seal assembly consists of an Elastomer O-Rings and a gland. An O-Ring is a circular cross-section ring molded from rubber. A properly designed O-ring groove allows the O-ring to be squeezed diametrically out-of-round even before the pressure is applied. The distortion of the O-ring’s resilient elastic compound fills the leakage path, thus, creating a seal.

Each O-Ring can be custom made to fit into your engineered gland, and when an O-Ring is applied to a properly designed gland, it will seal against a variety of high temperatures, cryogenic conditions, and chemicals.
