As a material, EPDM (EPR) is valued for outstanding weather, ozone and sunlight resistance, very good flexibility at low temperature. It resists ozone, UV and weathering, water and steam, and brake fluid. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C). Verify compatibility before use with petroleum oils and fuels or aromatic hydrocarbons.
Typical settings include brake and phosphate ester systems, HVAC and refrigeration, and solar and roofing assemblies.
This item is sold individually under part number E3X39.2. Check the compound against your process media, pressure and temperature before committing to a design.
