Part number E1.5X3.5 is a black EPDM (EPR) 70 Shore A O-Ring built to an inside diameter of 3.5 mm (0.138 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 6.5 mm (0.26 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces. Source specification: Metric O-RING, JIS S4.
EPDM (EPR) is specified here for good electrical insulating characteristics, excellent hot water and steam resistance. It resists phosphate ester hydraulic fluids, ketones, and water and steam. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service. Exposure to mineral oil-based lubricants or aromatic hydrocarbons will shorten service life.
It sees regular use in solar and roofing assemblies, water and steam systems, and brake and phosphate ester systems.
