This o-ring is supplied in AS568-322 black Buna-N (Nitrile) 70 Shore A with an inside diameter of 1.225 in (31.12 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.645 in (41.78 mm), catalogued under part number H70MD322. It compresses into its gland to block fluid or gas migration across a joint.
As a material, Buna-N (Nitrile) is specified for the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. It resists propane and butane, many alcohols, and greases and lubricants. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to ozone and direct sunlight or automotive brake fluid will shorten service life.
The compound is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across agricultural equipment, automotive, and fluid power.
This item is sold individually under part number H70MD322. Nominal inside diameter is listed as 1 1/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. Not finding the exact configuration you need?
