APG stocks the E70032, an AS568-032 black EPDM (EPR) 70 Shore A O-Ring measuring an inside diameter of 1.864 in (47.35 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.004 in (50.9 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Expect good resistance to ketones, dilute acids and alkalis, and brake fluid. That behavior comes from the compound itself: EPDM (EPR) is widely chosen for good electrical insulating characteristics, excellent hot water and steam resistance. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service. Verify compatibility before use with petroleum oils and fuels or aromatic hydrocarbons.
It sees regular use in HVAC and refrigeration, solar and roofing assemblies, and water and steam systems.
Order part number E70032, sold individually. Unit weight is approximately 0.465 g. Review your operating media and conditions against this specification before installation.
