H70MD395 is an AS568-395 black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 25.94 in (658.88 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 26.36 in (669.54 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
As a material, Buna-N (Nitrile) offers low compression set under sustained load, strong abrasion and tear resistance. The material holds up against propane and butane, water, and greases and lubricants. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids 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 automotive, fluid power, and agricultural equipment.
Stocked as H70MD395 and sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
