H2.4X20.8 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 20.8 mm (0.819 in), a cross section of 2.4 mm (0.094 in), and an outside diameter of 25.6 mm (1.01 in). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces. Source specification: Metric O-RING, JIS P21.
It resists hydraulic fluids, petroleum-based oils, and propane and butane. Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It is not the right choice where ozone and direct sunlight or ketones are present.
It sees regular use in construction equipment, fluid power, and agricultural equipment.
