1.6MM CS X 12.1MM ID BLACK BUNA 70D

APG stocks the H1.6X12.1, a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 12.1 mm (0.476 in), a cross section of 1.6 mm (0.063 in), and an outside diameter of 15.3 mm (0.6 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Buna-N (Nitrile) is known for strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. This material stands up to petroleum-based oils, many alcohols, and greases and lubricants. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving automotive brake fluid or polar solvents call for a different compound.

You will find this material specified across general industrial maintenance, agricultural equipment, and fluid power.
