The E2.5X112 is a black EPDM (EPR) 70 Shore A O-Ring measuring an inside diameter of 112 mm (4.409 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 117 mm (4.61 in). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.
EPDM (EPR) is valued for outstanding weather, ozone and sunlight resistance, very good flexibility at low temperature. It resists brake fluid, water and steam, and dilute acids and alkalis. Published continuous service range is -65°F (-53.9°C) to 300°F (148.9°C).
Common environments for this compound include solar and roofing assemblies, water and steam systems, and HVAC and refrigeration.
Stocked as E2.5X112 and sold individually. Unit weight is approximately 2.225 g. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
