**4362-366Y MINNESOTA RUBBER QUAD RING

Part number HQ4362 is an AS568-362 black Buna-N (Nitrile) 70 Shore A Quad-Ring supplied with an inside diameter of 6.225 in (158.12 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 6.645 in (168.78 mm). A quad-ring provides a dual sealing band on each contact face for improved reliability.

Buna-N (Nitrile) is specified here for economical choice for high-volume maintenance programs, strong abrasion and tear resistance. Expect good resistance to propane and butane, greases and lubricants, and many alcohols. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ozone and direct sunlight or automotive brake fluid are present. The profile itself contributes lower compressive load required to achieve a seal and resistance to the spiral twisting that defeats round-section rings.

It sees regular use in automotive, hydraulic and pneumatic systems, and agricultural equipment.
