APG stocks the E5.7X114.3, a black EPDM (EPR) 70 Shore A O-Ring built to an inside diameter of 114.3 mm (4.5 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 125.7 mm (4.95 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
EPDM (EPR) is specified here for outstanding weather, ozone and sunlight resistance, very good flexibility at low temperature. Expect good resistance to ketones, dilute acids and alkalis, and water and steam. Continuous operating temperature is published at -65°F (-53.9°C) to 300°F (148.9°C). Verify compatibility before use with aromatic hydrocarbons or petroleum oils and fuels.
Maintenance and OEM teams specify it across brake and phosphate ester systems, water and steam systems, and outdoor equipment.
E5.7X114.3 ships individually. Check the compound against your process media, pressure and temperature before committing to a design.
