EPDM (Ethylene Propylene Diene Monomer) O-rings are a type of sealing ring made from a synthetic rubber material. They are known for their excellent resistance to heat, ozone, and weathering, making them suitable for use in outdoor and high temperature applications. EPDM O-rings also have good chemical resistance and can withstand a wide range of fluids and chemicals. They are commonly used in automotive, industrial, and plumbing applications. Due to their durability and versatility, EPDM O-rings are a popular choice for many types of sealing applications.
