-017 BLACK BUNA 70D O-RING

The H70017 is an AS568-017 black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 0.676 in (17.17 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.816 in (20.73 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

This material stands up to hydraulic fluids, propane and butane, and water. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to polar solvents or ketones will shorten service life.

It sees regular use in automotive, fluid power, and hydraulic and pneumatic systems.

H70017 ships individually. Unit weight is approximately 0.1835 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
