M Barnwell Services stock an extensive variety of EPDM O Rings available in many sizes (Imperial and Metric) and shore hardness. With over 50 million O Rings and Back-Up Rings in stock, we supply to over 5000 customers worldwide.

EPDM Seals generally have a high resistance to hot water, steam, ageing, and chemicals, and are suitable for a wide range of temperature applications. This makes them ideal for industries such as Water, Pump and Gas, AutomotiveMarine and Aerospace and Defence.

EPDM can generally be used between –45°C and +130°C (peroxide-cured –50°C to +150°C).
