**4132-366Y MINNESOTA RUBBER QUAD RING

The HQ4132 is an AS568-132 black Buna-N (Nitrile) 70 Shore A Quad-Ring with an inside diameter of 1.737 in (44.12 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.943 in (49.35 mm). This quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

As a material, Buna-N (Nitrile) is widely chosen for the most widely specified general-purpose sealing elastomer and low compression set under sustained load. The compound resists propane and butane, water, and many alcohols. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Verify compatibility before use with strong acids or polar solvents. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and two sealing bands per contact face rather than one.

Common environments for this compound include automotive, construction equipment, and general industrial maintenance.

Stocked as HQ4132 and sold individually. Nominal inside diameter is listed as 1 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
