2.5MM CS X 18MM ID BLACK EPDM 70D

Ordered as E2.5X18, this is a black EPDM (EPR) 70 Shore A O-Ring supplied with an inside diameter of 18 mm (0.709 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 23 mm (0.91 in). The o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists water and steam, ketones, and ozone, UV and weathering. That behavior comes from the compound itself: EPDM (EPR) delivers very good flexibility at low temperature, strong performance in outdoor and exposed installations. Published continuous service range is -65°F (-53.9°C) to 300°F (148.9°C). Verify compatibility before use with mineral oil-based lubricants or aromatic hydrocarbons.

You will find this material specified across HVAC and refrigeration, water and steam systems, and solar and roofing assemblies.

E2.5X18 ships individually. Unit weight is approximately 0.401 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
