Product Specification

-
This o-ring is supplied in AS568-269 black Buna-N (Nitrile) 70 Shore A with an inside diameter of 8.734 in (221.84 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 9.012 in (228.9 mm), catalogued under part number H70MD269. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Buna-N (Nitrile) is widely chosen for strong abrasion and tear resistance, reliable performance in both static and dynamic service. Expect good resistance to petroleum-based oils, water, and many alcohols. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Verify compatibility before use with automotive brake fluid or ozone and direct sunlight.

The compound is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across general industrial maintenance, automotive, and hydraulic and pneumatic systems.

Order part number H70MD269, sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
