-412 BLACK BUNA 50D O-RING

The H50412 is an AS568-412 black Buna-N (Nitrile) 50 Shore A O-Ring measuring an inside diameter of 2.85 in (72.39 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.4 in (86.36 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Buna-N (Nitrile) is specified for the most widely specified general-purpose sealing elastomer and low compression set under sustained load. The material holds up against greases and lubricants, many alcohols, and hydraulic fluids. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to polar solvents or automotive brake fluid will shorten service life.

Common environments for this compound include fluid power, construction equipment, and automotive.

Stocked as H50412 and sold individually. Nominal inside diameter is listed as 2 7/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
