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, they 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 varying based on application needs. The most commonly used O-ring materials include nitrile rubber, silicone, EPDM rubber, and fluorocarbon (Viton).
Comprehensive Insights into O-Rings
O-rings are critical components in many industries, including automotive, aerospace, and medical. They are designed 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.
