3.5MM CS X 15MM ID BLACK EPDM 70D

APG stocks the E3.5X15, a black EPDM (EPR) 70 Shore A O-Ring built to an inside diameter of 15 mm (0.591 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 22 mm (0.87 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to ozone, UV and weathering, ketones, and phosphate ester hydraulic fluids. That behavior comes from the compound itself: EPDM (EPR) is valued for excellent hot water and steam resistance, strong performance in outdoor and exposed installations. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C). Verify compatibility before use with petroleum oils and fuels or aromatic hydrocarbons.

You will find this material specified across potable water applications, solar and roofing assemblies, and outdoor equipment.
