Top 10 Rubber Ring Suppliers in China 2026

Introduction to Rubber Rings

Rubber rings, also known as O - rings, are circular seals made of rubber or elastomeric materials. They are one of the most widely used sealing components in various industries. Their simple yet effective design allows them to create a reliable seal between two mating surfaces, preventing the leakage of fluids (liquids or gases) and protecting the internal components of machinery and equipment from contaminants.

Rubber rings come in a wide range of sizes, materials, and hardness levels to meet different application requirements. Common materials include nitrile rubber (NBR), fluorocarbon rubber (FKM), silicone rubber (VMQ), and ethylene - propylene - diene monomer (EPDM). Each material has its own unique properties, such as resistance to heat, chemicals, oil, and ozone. For example, NBR is known for its excellent oil resistance, making it suitable for automotive and hydraulic applications; FKM offers high - temperature and chemical resistance, which is ideal for aerospace and chemical processing industries.
