Product Specification

-
This o-ring is supplied in AS568-468 black Buna-N (Nitrile) 50 Shore A measuring an inside diameter of 19.455 in (494.16 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 20.005 in (508.13 mm), catalogued under part number H50468. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Buna-N (Nitrile) is valued for low compression set under sustained load and an economical choice for high-volume maintenance programs. The material holds up against propane and butane, many alcohols, and petroleum-based oils. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ketones or ozone and direct sunlight.

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

This item is sold individually under part number H50468. 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.
