*4133-366Y MINNESOTA RUBBER QUAD RING

Ordered as HQ4133, this is an AS568-133 black Buna-N (Nitrile) 70 Shore A quad profile Quad-Ring built to an inside diameter of 1.799 in (45.69 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.005 in (50.93 mm). The quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

This material stands up to water, petroleum-based oils, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ketones or ozone and direct sunlight are present.

Common environments for this compound include automotive, general industrial maintenance, and fluid power.

This item is sold individually under part number HQ4133. Nominal inside diameter is listed as 1.8125 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
