-457 BLACK EPDM 80D O-RING

Ordered as E80PC457, this is an AS568-457 black EPDM (EPR) 80 Shore A O-Ring measuring an inside diameter of 13.975 in (354.97 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 14.525 in (368.94 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

EPDM (EPR) delivers good electrical insulating characteristics and very good flexibility at low temperature. The material holds up against dilute acids and alkalis, ozone, UV and weathering, and phosphate ester hydraulic fluids. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service. Applications involving aromatic hydrocarbons or mineral oil-based lubricants call for a different compound.

Typical settings include water and steam systems, solar and roofing assemblies, and HVAC and refrigeration.

Reference part number E80PC457 when ordering; the item is sold individually. Nominal inside diameter is listed as 14 inch. Check the compound against your process media, pressure and temperature before committing to a design.
