Product Specification

-
This o-ring is supplied in AS568-262 black Buna-N (Nitrile) 50 Shore A with an inside diameter of 6.984 in (177.39 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 7.262 in (184.45 mm), catalogued under part number H50262. It creates a positive seal at flange, piston and rod interfaces without added hardware.

Buna-N (Nitrile) is widely chosen for low compression set under sustained load, strong abrasion and tear resistance. This material stands up to greases and lubricants, petroleum-based oils, and hydraulic fluids. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where strong acids or automotive brake fluid are present.

Common environments for this compound include general industrial maintenance, hydraulic and pneumatic systems, and construction equipment.

Order part number H50262, sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
