Ordered as HQ4047, this is an AS568-047 black Buna-N (Nitrile) 70 Shore A Quad-Ring built to an inside diameter of 4.489 in (114.02 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 4.629 in (117.58 mm). The quad-ring provides a dual sealing band on each contact face for improved reliability.
Expect good resistance to greases and lubricants, propane and butane, and petroleum-based oils. Buna-N (Nitrile) offers strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). The profile itself contributes two sealing bands per contact face rather than one and lower compressive load required to achieve a seal.
Typical settings include automotive, agricultural equipment, and general industrial maintenance.
Order part number HQ4047, sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
