E3X37 is a black EPDM (EPR) 70 Shore A O-Ring supplied with an inside diameter of 37 mm (1.457 in), a cross section of 3 mm (0.118 in), and an outside diameter of 43 mm (1.69 in). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.
EPDM (EPR) offers outstanding weather, ozone and sunlight resistance, excellent hot water and steam resistance. This material stands up to brake fluid, phosphate ester hydraulic fluids, and ozone, UV and weathering. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C). It is not the right choice where aromatic hydrocarbons or mineral oil-based lubricants are present.
Typical settings include solar and roofing assemblies, water and steam systems, and brake and phosphate ester systems.
Stocked as E3X37 and sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
