-217 BLACK EPDM 70D O-RING

APG stocks the E70217, an AS568-217 black EPDM (EPR) 70 Shore A O-Ring measuring an inside diameter of 1.171 in (29.74 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.449 in (36.8 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to ozone, UV and weathering, phosphate ester hydraulic fluids, and dilute acids and alkalis. That behavior comes from the compound itself: EPDM (EPR) is widely chosen for strong performance in outdoor and exposed installations, excellent hot water and steam resistance. Continuous operating temperature is published at -65°F (-53.9°C) to 300°F (148.9°C). It should not be specified for service in mineral oil-based lubricants or petroleum oils and fuels.

Maintenance and OEM teams specify it across solar and roofing assemblies, potable water applications, and water and steam systems.

Order part number E70217, sold individually. Unit weight is approximately 0.0012 g and nominal inside diameter is listed as 1 3/16 inch. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
