*4441-366Y MINNESOTA RUBBER QUAD RING

The HQ4441 is an AS568-441 black Buna-N (Nitrile) 70 Shore A quad profile Quad-Ring supplied with an inside diameter of 6.975 in (177.17 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 7.525 in (191.14 mm). This quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

Buna-N (Nitrile) is valued for the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. The material holds up against hydraulic fluids, water, and propane and butane. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to ketones or polar solvents will shorten service life.

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

Stocked as HQ4441 and sold individually. Nominal inside diameter is listed as 7 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
