Part number E4X32 is a black EPDM (EPR) 70 Shore A O-Ring built to an inside diameter of 32 mm (1.26 in), a cross section of 4 mm (0.157 in), and an outside diameter of 40 mm (1.57 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
EPDM (EPR) is specified here for strong performance in outdoor and exposed installations, outstanding weather, ozone and sunlight resistance. The material holds up against ketones, brake fluid, and ozone, UV and weathering. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C). Applications involving petroleum oils and fuels or mineral oil-based lubricants call for a different compound.
You will find this material specified across solar and roofing assemblies, HVAC and refrigeration, and potable water applications.
Stocked as E4X32 and sold individually. Unit weight is approximately 1.79 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
