-231 BLACK EPDM 80D O-RING

The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

That behavior comes from the compound itself: EPDM (EPR) delivers excellent hot water and steam resistance, good electrical insulating characteristics. Published continuous service range is -65°F (-53.9°C) to 300°F (148.9°C).

Maintenance and OEM teams specify it across outdoor equipment, HVAC and refrigeration, and solar and roofing assemblies.
