Part number H2X112 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 112 mm (4.409 in), a cross section of 2 mm (0.079 in), and an outside diameter of 116 mm (4.57 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
Expect good resistance to hydraulic fluids, petroleum-based oils, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen 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). It should not be specified for service in polar solvents or ketones.
It sees regular use in general industrial maintenance, agricultural equipment, and construction equipment.
H2X112 ships individually. Unit weight is approximately 1.3681 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
