4367-366Y MINNESOTA RUBBER QUAD RING

APG stocks the HQ4367, an AS568-367 black Buna-N (Nitrile) 70 Shore A Quad-Ring built to an inside diameter of 7.475 in (189.87 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 7.895 in (200.53 mm). A quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

The compound resists water, many alcohols, and hydraulic fluids. Buna-N (Nitrile) is specified for reliable performance in both static and dynamic service, low compression set under sustained load. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. The profile itself contributes a parting line located away from the sealing surface and lower compressive load required to achieve a seal.

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