This o-ring is supplied in black EPDM (EPR) 70 Shore A measuring an inside diameter of 219.3 mm (8.634 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 230.7 mm (9.08 in), catalogued under part number E5.7X219.3. It remains the most cost-effective sealing element available for pressurized assemblies. This item is further identified as Metric O-RING, JIS G220.
The compound resists phosphate ester hydraulic fluids, ozone, UV and weathering, and water and steam. That behavior comes from the compound itself: EPDM (EPR) is widely chosen for excellent hot water and steam resistance, good electrical insulating characteristics. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service. It is not the right choice where petroleum oils and fuels or mineral oil-based lubricants are present.
Typical settings include brake and phosphate ester systems, outdoor equipment, and potable water applications.
E5.7X219.3 ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
