APG stocks the E2.5X45, a black EPDM (EPR) 70 Shore A O-Ring with an inside diameter of 45 mm (1.772 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 50 mm (1.97 in). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.
The material holds up against phosphate ester hydraulic fluids, brake fluid, and ozone, UV and weathering. That behavior comes from the compound itself: EPDM (EPR) is widely chosen for outstanding weather, ozone and sunlight resistance, very good flexibility at low temperature. Published continuous service range is -65°F (-53.9°C) to 300°F (148.9°C). Exposure to petroleum oils and fuels or aromatic hydrocarbons will shorten service life.
Maintenance and OEM teams specify it across brake and phosphate ester systems, HVAC and refrigeration, and water and steam systems.
Stocked as E2.5X45 and sold individually. Unit weight is approximately 0.955 g. Check the compound against your process media, pressure and temperature before committing to a design.
