**4170-366Y MINNESOTA RUBBER QUAD RING

HQ4170 is an AS568-170 black Buna-N (Nitrile) 70 Shore A quad profile Quad-Ring built to an inside diameter of 7.737 in (196.52 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 7.943 in (201.75 mm). In service, this quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

It resists many alcohols, water, and hydraulic fluids. Buna-N (Nitrile) offers strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with polar solvents or automotive brake fluid.

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

HQ4170 ships individually. Nominal inside diameter is listed as 7 3/4. As always, verify media compatibility and operating conditions against the requirements of your specific application.
