568-151 BUNA 70 SQUARE CUT RINGS

APG stocks the SH70151, an AS568-151 black Buna-N (Nitrile) 70 Shore A square profile Quad-Ring built to an inside diameter of 2.987 in (75.87 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.193 in (81.1 mm). A quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

This material stands up to hydraulic fluids, water, and many alcohols. Buna-N (Nitrile) is widely chosen for the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C).

Common environments for this compound include hydraulic and pneumatic systems, agricultural equipment, and construction equipment.

Order part number SH70151, sold individually. Unit weight is approximately 1.9341 g. Check the compound against your process media, pressure and temperature before committing to a design.
