O Rings Supplier - China

price: contact company for price

O-Rings are circular rubber sealing elements widely used in hydraulic and pneumatic systems.

With strong sealing performance, they support both static and dynamic applications and can be used alone or within composite sealing structures.

When paired with suitable materials, O-Rings handle extreme pressures, broad temperature ranges, and diverse operating conditions across many industries.

O-rings, also known as O-rings seals, are rubber rings with a circular cross-section.

O-rings seals are the most widely used sealing components in hydraulic and pneumatic sealing systems.

O-rings have excellent sealing properties and can be used for both static sealing and reciprocating motion sealing; they can be used alone or as a basic component of many composite sealing assemblies.

Their application range is very broad, and if the material is selected appropriately, they can meet the requirements of various motion conditions, with operating pressures ranging from 1.333×10⁵ Pa vacuum to 400 MPa high pressure; the temperature range can be from -60°C to 200°C.

We offer O-ring rubber seals in a variety of sizes and materials, and can also customize them according to your needs.
