The SH70131 is an AS568-131 black Buna-N (Nitrile) 70 Shore A square profile Quad-Ring with an inside diameter of 1.674 in (42.52 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.88 in (47.75 mm). This quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.
This material stands up to propane and butane, greases and lubricants, and hydraulic fluids. Buna-N (Nitrile) is specified for reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to ozone and direct sunlight or ketones will shorten service life.
Typical settings include construction equipment, hydraulic and pneumatic systems, and automotive.
SH70131 ships individually. Unit weight is approximately 1.0788 g and nominal inside diameter is listed as 1 11/16 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
