-315 BLACK EPDM 80D O-RING

The E80PC315 is an AS568-315 black EPDM (EPR) 80 Shore A O-Ring with an inside diameter of 0.787 in (19.99 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.207 in (30.66 mm). This o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against brake fluid, ketones, and phosphate ester hydraulic fluids. That behavior comes from the compound itself: EPDM (EPR) delivers 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).

Maintenance and OEM teams specify it across brake and phosphate ester systems, solar and roofing assemblies, and outdoor equipment.
