-913 BLACK BUNA 70D O-RING

Ordered as H70MD913, this is an AS568-913 black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 0.986 in (25.04 mm), a cross section of 0.116 in (2.95 mm), and an outside diameter of 1.218 in (30.94 mm). The o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The compound resists greases and lubricants, water, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, strong abrasion and tear resistance. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where automotive brake fluid or ketones are present.

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