Ordered as H5.7X69.2, this is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 69.2 mm (2.724 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 80.6 mm (3.17 in). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The compound resists many alcohols, propane and butane, and petroleum-based oils. Buna-N (Nitrile) is valued for an economical choice for high-volume maintenance programs 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 polar solvents call for a different compound.

Typical settings include fluid power, automotive, and agricultural equipment.
