Top 10 O-Ring Manufacturers and Suppliers in China (2024)
O-rings have got their name because of their circular cross-section. They act as essential sealants by providing a protective layer between components, preventing leakage of liquids or gases. Due to their versatility, O-rings can be used for both static and dynamic applications. Various manufacturing techniques like injection, extrusion, and compression molding are employed to produce O-rings, with materials chosen based on specific applications. The most commonly used materials include nitrile rubber, silicone, EPDM rubber, and fluorocarbon (Viton).
Comprehensive Insights into O-Rings
O-rings are critical components in various industries, including automotive, aerospace, and medical. Their primary function is to create a seal between two surfaces, preventing the escape of fluids or gases. The effectiveness of an O-ring depends on its material, size, and the conditions under which it operates.
