O-rings, named for their circular cross-section, are crucial sealants providing a protective barrier between components. They prevent leakage of liquids or gases, finding applications in static and dynamic systems. Manufacturing techniques include injection, extrusion, and compression molding, with material selection depending on the specific application. Common materials include nitrile rubber, silicone, EPDM rubber, and fluorocarbon (Viton). This guide explores the world of O-rings, focusing on Chinese manufacturers and suppliers.
