As a material, EPDM (EPR) is valued for very good flexibility at low temperature, strong performance in outdoor and exposed installations. The material holds up against water and steam, ketones, and brake fluid. Published continuous service range is -65°F (-53.9°C) to 300°F (148.9°C). Verify compatibility before use with petroleum oils and fuels or mineral oil-based lubricants.
