1.6MM CS X 19.1MM ID BLACK BUNA 70D

APG stocks the H1.6X19.1, a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 19.1 mm (0.752 in), a cross section of 1.6 mm (0.063 in), and an outside diameter of 22.3 mm (0.88 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against hydraulic fluids, greases and lubricants, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for reliable performance in both static and dynamic service, low compression set under sustained load. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving strong acids or polar solvents call for a different compound.

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

This item is sold individually under part number H1.6X19.1. As always, verify media compatibility and operating conditions against the requirements of your specific application.
