Ethylene-propylene (EPM/EPDM) These compounds have excellent resistance to weathering, ozone, hot and cold water and steam.
Chemical properties 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 service 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.
Our EP62 range is WRAS approved for potable water applications.
James Walker standard grades Supplied in hardnesses 50-90 IRHD.
