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.
This item is sold individually under part number E80PC315. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
