Ordered as E3X24.2, this is a black EPDM (EPR) 70 Shore A O-Ring measuring an inside diameter of 24.2 mm (0.953 in), a cross section of 3 mm (0.118 in), and an outside diameter of 30.2 mm (1.19 in). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
Expect good resistance to phosphate ester hydraulic fluids, ketones, and ozone, UV and weathering. That behavior comes from the compound itself: EPDM (EPR) offers very good flexibility at low temperature, outstanding weather, ozone and sunlight resistance. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C).
You will find this material specified across solar and roofing assemblies, brake and phosphate ester systems, and HVAC and refrigeration.
