Product Specification

-
This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A built to an inside diameter of 212 mm (8.346 in), a cross section of 5 mm (0.197 in), and an outside diameter of 222 mm (8.74 in), catalogued under part number H5X212. It creates a positive seal at flange, piston and rod interfaces without added hardware.

Buna-N (Nitrile) is widely chosen for the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. Expect good resistance to hydraulic fluids, many alcohols, and propane and butane. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It should not be specified for service in ozone and direct sunlight or strong acids.

Typical settings include automotive, general industrial maintenance, and hydraulic and pneumatic systems.

H5X212 ships individually. Unit weight is approximately 17.152 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
