568-394 BUNA 70 SQUARE CUT RINGS

Ordered as SH70394, this is an AS568-394 black Buna-N (Nitrile) 70 Shore A square profile Quad-Ring built to an inside diameter of 24.94 in (633.48 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 25.36 in (644.14 mm). The quad-ring provides a dual sealing band on each contact face for improved reliability.

As a material, Buna-N (Nitrile) is specified for an economical choice for high-volume maintenance programs and low compression set under sustained load. It resists petroleum-based oils, propane and butane, and water. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to ozone and direct sunlight or strong acids will shorten service life.

Common environments for this compound include hydraulic and pneumatic systems, construction equipment, and general industrial maintenance.

SH70394 ships individually. Nominal inside diameter is listed as 25 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
