**4271-366Y MINNESOTA RUBBER QUAD RING

Ordered as HQ4271, this is an AS568-271 black Buna-N (Nitrile) 70 Shore A Quad-Ring built to an inside diameter of 9.234 in (234.54 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 9.512 in (241.6 mm). The quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Buna-N (Nitrile) offers low compression set under sustained load, strong abrasion and tear resistance. It resists petroleum-based oils, propane and butane, and many alcohols. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ozone and direct sunlight or polar solvents are present. The profile itself contributes a parting line located away from the sealing surface and resistance to the spiral twisting that defeats round-section rings.

Typical settings include automotive, fluid power, and agricultural equipment.

This item is sold individually under part number HQ4271. As always, verify media compatibility and operating conditions against the requirements of your specific application.
