Buna 70-003-Black-Pk100

SB-H70003-100 is an AS568-003 black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 0.056 in (1.42 mm), a cross section of 0.06 in (1.52 mm), and an outside diameter of 0.176 in (4.47 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware. The catalog record notes:0.1875IDX.0625"ODX.0625"CS.

Expect good resistance to greases and lubricants, petroleum-based oils, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for strong abrasion and tear resistance, reliable performance in both static and dynamic service. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in automotive brake fluid or strong acids.

Typical settings include hydraulic and pneumatic systems, fluid power, and general industrial maintenance.
