This o-ring is supplied in AS568-027 black Buna-N (Nitrile) 70 Shore A supplied with an inside diameter of 1.301 in (33.05 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.441 in (36.6 mm), catalogued under part number H70MD027. It creates a positive seal at flange, piston and rod interfaces without added hardware.
This material stands up to petroleum-based oils, hydraulic fluids, and many alcohols. Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to strong acids or polar solvents 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, general industrial maintenance, and hydraulic and pneumatic systems.
Order part number H70MD027, sold individually. Nominal inside diameter is listed as 1 5/16 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
