2.5MM CS X 128MM ID BLACK EPDM 70D

Part number E2.5X128 is a black EPDM (EPR) 70 Shore A O-Ring supplied with an inside diameter of 128 mm (5.039 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 133 mm (5.24 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

EPDM (EPR) is specified here for excellent hot water and steam resistance, strong performance in outdoor and exposed installations. It resists dilute acids and alkalis, phosphate ester hydraulic fluids, and brake fluid. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C). It should not be specified for service in mineral oil-based lubricants or aromatic hydrocarbons.

Common environments for this compound include potable water applications, brake and phosphate ester systems, and water and steam systems.

E2.5X128 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
