Part number SH70358 is an AS568-358 black Buna-N (Nitrile) 70 Shore A square profile Quad-Ring supplied with an inside diameter of 5.6 in (142.24 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 6.02 in (152.91 mm). A quad-ring provides a dual sealing band on each contact face for improved reliability.
The compound resists hydraulic fluids, petroleum-based oils, and water. That behavior comes from the compound itself: Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to automotive brake fluid or ozone and direct sunlight will shorten service life.
Typical settings include agricultural equipment, general industrial maintenance, and hydraulic and pneumatic systems.
This item is sold individually under part number SH70358. Nominal inside diameter is listed as 5 5/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
