Top 10 EPDM O Ring Suppliers in China

Introduction to EPDM O Rings

EPDM (Ethylene Propylene Diene Monomer) O - rings are a type of elastomeric sealing device. They are made from EPDM rubber, which is known for its excellent resistance to weathering, ozone, and oxidation. EPDM O - rings can withstand a wide range of temperatures, typically from - 40°C to 120°C, and are highly resistant to many chemicals, including polar solvents, water, and steam. These properties make them suitable for a variety of applications, such as automotive, plumbing, electrical, and industrial equipment, where they are used to prevent the leakage of fluids or gases.
