An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
The compound resists dilute acids and alkalis, water and steam, and ozone, UV and weathering. That behavior comes from the compound itself: EPDM (EPR) is widely chosen for excellent hot water and steam resistance, outstanding weather, ozone and sunlight resistance. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service.
It sees regular use in water and steam systems, HVAC and refrigeration, and solar and roofing assemblies.
