APG stocks the HQ4169, an AS568-169 black Buna-N (Nitrile) 70 Shore A Quad-Ring with an inside diameter of 7.487 in (190.17 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 7.693 in (195.4 mm). A quad-ring provides a dual sealing band on each contact face for improved reliability.
Buna-N (Nitrile) is specified for the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. This material stands up to petroleum-based oils, greases and lubricants, and water. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). The profile itself contributes a parting line located away from the sealing surface and two sealing bands per contact face rather than one.
Typical settings include automotive, construction equipment, and fluid power.
Stocked as HQ4169 and sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
