APG stocks the E3X65, a black EPDM (EPR) 70 Shore A O-Ring built to an inside diameter of 65 mm (2.559 in), a cross section of 3 mm (0.118 in), and an outside diameter of 71 mm (2.8 in). An o-ring compresses into its gland to block fluid or gas migration across a joint.
The compound resists phosphate ester hydraulic fluids, dilute acids and alkalis, and ozone, UV and weathering. That behavior comes from the compound itself: EPDM (EPR) is specified for good electrical insulating characteristics, strong performance in outdoor and exposed installations. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C). Exposure to aromatic hydrocarbons or petroleum oils and fuels will shorten service life.
You will find this material specified across potable water applications, HVAC and refrigeration, and outdoor equipment.
This item is sold individually under part number E3X65. Unit weight is approximately 0.0018 g. 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.
