Ethylene-propylene (EPM/EPDM)

Ethylene-propylene (EPM/EPDM)
These compounds have excellent resistance to weathering, ozone, hot and cold water, and steam.

They display resistance to aliphatic phosphate-ester hydraulic fluids, acids, alkalis, salt solutions, alcohols, glycols and silicone oils.

Typical operating temperatures
-45°C to +120°C continuous, or +150°C intermittent. EPM grades are available for use with hot water up to +180°C.   

Fluid sealing duties
Often used with steam raising plant. They must not be used with mineral oils or di-ester based lubricants.

O-rings in our EP62 range are WRAS approved for cold and hot potable water applications up to 85°C.

Standard grades
Supplied in hardnesses 50-90 IRHD.

O-ring stocked grade
EP18/H/75.
