4MM CS X 18MM ID BLACK EPDM 70D

APG stocks the E4x18, a black EPDM (EPR) 70 Shore A O-Ring with an inside diameter of 18 mm (0.709 in), a cross section of 4 mm (0.157 in), and an outside diameter of 26 mm (1.02 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, EPDM (EPR) is valued for very good flexibility at low temperature, outstanding weather, ozone and sunlight resistance. The material holds up against ozone, UV and weathering, water and steam, and ketones. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C).

You will find this material specified across potable water applications, outdoor equipment, and HVAC and refrigeration.

Stocked as E4x18 and sold individually. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
