E3X30 is a black EPDM (EPR) 70 Shore A O-Ring built to an inside diameter of 30 mm (1.181 in), a cross section of 3 mm (0.118 in), and an outside diameter of 36 mm (1.42 in). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
EPDM (EPR) is specified here for very good flexibility at low temperature, excellent hot water and steam resistance. Expect good resistance to ketones, dilute acids and alkalis, and phosphate ester hydraulic fluids. Published continuous service range is -65°F (-53.9°C) to 300°F (148.9°C). Verify compatibility before use with aromatic hydrocarbons or mineral oil-based lubricants.
Maintenance and OEM teams specify it across water and steam systems, solar and roofing assemblies, and HVAC and refrigeration.
This item is sold individually under part number E3X30. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
