Product Specification

-
H50164 is an AS568-164 black Buna-N (Nitrile) 50 Shore A O-Ring supplied with an inside diameter of 6.237 in (158.42 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 6.443 in (163.65 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Buna-N (Nitrile) is known for strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. This material stands up to greases and lubricants, propane and butane, and petroleum-based oils. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Applications involving strong acids or automotive brake fluid call for a different compound.

You will find this material specified across construction equipment, automotive, and hydraulic and pneumatic systems.

This item is sold individually under part number H50164. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
