-125 BLACK EPDM 70D O-RING

Part number E70125 is an AS568-125 black EPDM (EPR) 70 Shore A O-Ring with an inside diameter of 1.299 in (32.99 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.505 in (38.23 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

It resists phosphate ester hydraulic fluids, dilute acids and alkalis, and ketones. That behavior comes from the compound itself: EPDM (EPR) delivers excellent hot water and steam resistance, outstanding weather, ozone and sunlight resistance. Published continuous service range is -65°F (-53.9°C) to 300°F (148.9°C). Exposure to petroleum oils and fuels or mineral oil-based lubricants will shorten service life.

Maintenance and OEM teams specify it across solar and roofing assemblies, HVAC and refrigeration, and water and steam systems.

Stocked as E70125 and sold individually. Unit weight is approximately 0.0007 g and nominal inside diameter is listed as 1 5/16 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
