*4361-366Y MINNESOTA RUBBER QUAD RING

HQ4361 is an AS568-361 black Buna-N (Nitrile) 70 Shore A Quad-Ring with an inside diameter of 5.975 in (151.77 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 6.395 in (162.43 mm). In service, this quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

As a material, Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. The compound resists many alcohols, greases and lubricants, and hydraulic fluids. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving ozone and direct sunlight or polar solvents call for a different compound. The profile itself contributes a parting line located away from the sealing surface and two sealing bands per contact face rather than one.

It sees regular use in general industrial maintenance, agricultural equipment, and fluid power.
