4459-366Y MINNESOTA RUBBER QUAD RING

APG stocks the HQ4459, an AS568-459 black Buna-N (Nitrile) 70 Shore A Quad-Ring supplied with an inside diameter of 14.975 in (380.37 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 15.525 in (394.34 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Expect good resistance to greases and lubricants, petroleum-based oils, and hydraulic fluids. Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer and an economical choice for high-volume maintenance programs. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Verify compatibility before use with automotive brake fluid or ketones. The profile itself contributes lower compressive load required to achieve a seal and a parting line located away from the sealing surface.

Typical settings include general industrial maintenance, hydraulic and pneumatic systems, and construction equipment.

Stocked as HQ4459 and sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
