Ordered as H70MD024, this is an AS568-024 black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 1.114 in (28.3 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.254 in (31.85 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
Buna-N (Nitrile) is widely chosen for strong abrasion and tear resistance, reliable performance in both static and dynamic service. It resists hydraulic fluids, water, and propane and butane. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving ozone and direct sunlight or ketones call for a different compound.
The compound is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across automotive, general industrial maintenance, and fluid power.
Reference part number H70MD024 when ordering; the item is sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
