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.
Stocked as E2.5X16 and sold individually. Unit weight is approximately 0.355 g. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
