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.
Order part number E3.5X15, sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
