Silicone O-rings are circular seals made from high-quality silicone rubber, known for their flexibility and durability. They can withstand extreme temperatures, typically ranging from -60°C to 230°C (-76°F to 446°F), making them suitable for various applications. These O-rings exhibit excellent chemical resistance, including oils and solvents, and are commonly used in automotive, aerospace, food processing, and pharmaceutical industries.

EPDM (Ethylene Propylene Diene Monomer) O-rings are versatile sealing components known for their excellent resistance to heat, ozone, and weathering. These synthetic rubber O-rings are ideal for outdoor applications and environments exposed to UV light. They can withstand temperatures ranging from -50°C to 150°C (-58°F to 302°F), making them suitable for various industrial, automotive, and HVAC applications. EPDM O-rings also offer good resistance to water, steam, and many chemicals, although they may not perform well with oils or petroleum products.
