APG stocks the SH70035, an AS568-035 black Buna-N (Nitrile) 70 Shore A square profile Quad-Ring built to an inside diameter of 2.239 in (56.87 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.379 in (60.43 mm). A quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Buna-N (Nitrile) delivers the most widely specified general-purpose sealing elastomer and an economical choice for high-volume maintenance programs. The material holds up against greases and lubricants, propane and butane, and petroleum-based oils. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to ozone and direct sunlight or automotive brake fluid will shorten service life.

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

SH70035 ships individually. Unit weight is approximately 0.56 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
