In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
It resists water and steam, ketones, and phosphate ester hydraulic fluids. EPDM (EPR) is specified for good electrical insulating characteristics, excellent hot water and steam resistance. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C). It should not be specified for service in mineral oil-based lubricants or aromatic hydrocarbons.
You will find this material specified across HVAC and refrigeration, water and steam systems, and outdoor equipment.
E70104 ships individually. Unit weight is approximately 0.108 g and nominal inside diameter is listed as 1/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
