-135 BLACK BUNA 50D O-RING

H50135 is an AS568-135 black Buna-N (Nitrile) 50 Shore A O-Ring measuring an inside diameter of 1.925 in (48.9 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.131 in (54.13 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists petroleum-based oils, propane and butane, and water. Buna-N (Nitrile) is valued for low compression set under sustained load and the most widely specified general-purpose sealing elastomer. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to ketones or strong acids will shorten service life.

Typical settings include fluid power, agricultural equipment, and general industrial maintenance.

Stocked as H50135 and sold individually. Nominal inside diameter is listed as 1 15/16 inch. Review your operating media and conditions against this specification before installation.
