Product Specification

-
APG stocks the E80PC388, an AS568-388 black EPDM (EPR) 80 Shore A O-Ring measuring an inside diameter of 18.953 in (481.41 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 19.373 in (492.07 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against water and steam, ketones, and dilute acids and alkalis. EPDM (EPR) delivers excellent hot water and steam resistance, outstanding weather, ozone and sunlight resistance. Published continuous service range is -65°F (-53.9°C) to 300°F (148.9°C). Exposure to mineral oil-based lubricants or aromatic hydrocarbons will shorten service life.

It sees regular use in HVAC and refrigeration, water and steam systems, and potable water applications.

Order part number E80PC388, sold individually. Nominal inside diameter is listed as 19 inch. Check the compound against your process media, pressure and temperature before committing to a design.
