Product Specification

-
H50154 is an AS568-154 black Buna-N (Nitrile) 50 Shore A O-Ring supplied with an inside diameter of 3.737 in (94.92 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.943 in (100.15 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Buna-N (Nitrile) delivers reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. This material stands up to hydraulic fluids, greases and lubricants, and propane and butane. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where polar solvents or ozone and direct sunlight are present.

Maintenance and OEM teams specify it across agricultural equipment, hydraulic and pneumatic systems, and fluid power.
