APG stocks the E3X114, a black EPDM (EPR) 70 Shore A O-Ring built to an inside diameter of 114 mm (4.488 in), a cross section of 3 mm (0.118 in), and an outside diameter of 120 mm (4.72 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
The material holds up against brake fluid, phosphate ester hydraulic fluids, and water and steam. That behavior comes from the compound itself: EPDM (EPR) offers strong performance in outdoor and exposed installations, 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). Verify compatibility before use with mineral oil-based lubricants or petroleum oils and fuels.
It sees regular use in solar and roofing assemblies, brake and phosphate ester systems, and HVAC and refrigeration.
E3X114 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
