O-rings are made of many materials. If these materials are classified according to oil resistance, they can be divided into polar rubber (that is, oil-resistant rubber) and non-polar rubber (that is, non-oil-resistant rubber).

With the continuous development and progress of the manufacturing industry, O-rings and gaskets are widely used in industry and life.

With the needs of production and life, people have put forward higher requirements for sealing products.

O-ring seals have requirements for the installation environment during installation. At the same time, it does not mean that the installation is complete.

It is suitable for use in petroleum-based hydraulic oil, glycol-based hydraulic oil, diester-based lubricating oil, gasoline, water, silicone grease, silicone oil and other media.

O-ring is a kind of non-metallic gasket, which belongs to static seal, a common rubber ring with a circular cross-section. Similarly, O-rings are the most widely used seals in hydraulic and pneumatic systems.
