Part number E80PC330 is an AS568-330 black EPDM (EPR) 80 Shore A O-Ring measuring an inside diameter of 2.1 in (53.34 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.52 in (64.01 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.
This material stands up to phosphate ester hydraulic fluids, ozone, UV and weathering, and water and steam. That behavior comes from the compound itself: EPDM (EPR) offers excellent hot water and steam resistance, very good flexibility at low temperature. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service. Verify compatibility before use with mineral oil-based lubricants or petroleum oils and fuels.
Maintenance and OEM teams specify it across water and steam systems, potable water applications, and solar and roofing assemblies.
E80PC330 ships individually. Nominal inside diameter is listed as 2 1/8 inch. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
