-907 BLACK BUNA 70D O-RING

H70MD907 is an AS568-907 black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 0.53 in (13.46 mm), a cross section of 0.082 in (2.08 mm), and an outside diameter of 0.694 in (17.63 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

This material stands up to water, greases and lubricants, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for the most widely specified general-purpose sealing elastomer and low compression set under sustained load. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving automotive brake fluid or ketones call for a different compound.

This o-ring is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across general industrial maintenance, agricultural equipment, and hydraulic and pneumatic systems.

H70MD907 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
