Product Specification

-
H70MD166 is an AS568-166 black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 6.737 in (171.12 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 6.943 in (176.35 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Buna-N (Nitrile) delivers strong abrasion and tear resistance, reliable performance in both static and dynamic service. This material stands up to greases and lubricants, many alcohols, and water. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service.

The compound is metal detectable for HACCP and foreign-body control programs. Typical settings include general industrial maintenance, hydraulic and pneumatic systems, and fluid power.
