2.5MM CS X 16MM ID BLACK EPDM 70D

E2.5X16 is a black EPDM (EPR) 70 Shore A O-Ring built to an inside diameter of 16 mm (0.63 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 21 mm (0.83 in). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

EPDM (EPR) is specified here for outstanding weather, ozone and sunlight resistance, excellent hot water and steam resistance. Expect good resistance to ketones, ozone, UV and weathering, and phosphate ester hydraulic fluids. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C).

Maintenance and OEM teams specify it across potable water applications, solar and roofing assemblies, and outdoor equipment.
