Ordered as E2X28, this is a black EPDM (EPR) 70 Shore A O-Ring supplied with an inside diameter of 28 mm (1.102 in), a cross section of 2 mm (0.079 in), and an outside diameter of 32 mm (1.26 in). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
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 valued for excellent hot water and steam resistance, strong performance in outdoor and exposed installations.

Typical settings include solar and roofing assemblies, HVAC and refrigeration, and potable water applications.
Reference part number E2X28 when ordering; the item is sold individually. Unit weight is approximately 0.3949 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
