Part number E70344 is an AS568-344 black EPDM (EPR) 70 Shore A O-Ring with an inside diameter of 3.85 in (97.79 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.27 in (108.46 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.
As a material, EPDM (EPR) offers excellent hot water and steam resistance, outstanding weather, ozone and sunlight resistance. The material holds up against water and steam, ketones, and phosphate ester hydraulic fluids. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service. Exposure to aromatic hydrocarbons or petroleum oils and fuels will shorten service life.
You will find this material specified across outdoor equipment, HVAC and refrigeration, and solar and roofing assemblies.
