Ordered as SH70392, this is an AS568-392 black Buna-N (Nitrile) 70 Shore A square profile Quad-Ring with an inside diameter of 22.94 in (582.68 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 23.36 in (593.34 mm). The quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.
As a material, Buna-N (Nitrile) is specified for the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. The material holds up against greases and lubricants, hydraulic fluids, and petroleum-based oils. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving strong acids or ozone and direct sunlight call for a different compound.
Maintenance and OEM teams specify it across construction equipment, automotive, and hydraulic and pneumatic systems.
Order part number SH70392, sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
