*4315-366Y MINNESOTA RUBBER QUAD RING

Part number HQ4315 is an AS568-315 black Buna-N (Nitrile) 70 Shore A quad profile Quad-Ring built to an inside diameter of 0.787 in (19.99 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.207 in (30.66 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

This material stands up to many alcohols, greases and lubricants, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for reliable performance in both static and dynamic service, strong abrasion and tear resistance. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to ketones or ozone and direct sunlight will shorten service life.

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