Ordered as E2X19, this is a black EPDM (EPR) 70 Shore A O-Ring with an inside diameter of 19 mm (0.748 in), a cross section of 2 mm (0.079 in), and an outside diameter of 23 mm (0.91 in). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
Expect good resistance to water and steam, dilute acids and alkalis, and ozone, UV and weathering. That behavior comes from the compound itself: EPDM (EPR) is known for good electrical insulating characteristics and very good flexibility at low temperature. Published continuous service range is -65°F (-53.9°C) to 300°F (148.9°C). It should not be specified for service in petroleum oils and fuels or mineral oil-based lubricants.
Maintenance and OEM teams specify it across potable water applications, water and steam systems, and solar and roofing assemblies.
E2X19 ships individually. Unit weight is approximately 0.269 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
