Q-231 BUNA 70 Q RING

QH70231 is an AS568-231 black Buna-N (Nitrile) 70 Shore A Quad-Ring supplied with an inside diameter of 2.609 in (66.27 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.887 in (73.33 mm). In service, this quad-ring provides a dual sealing band on each contact face for improved reliability.

Expect good resistance to greases and lubricants, water, and petroleum-based oils. Buna-N (Nitrile) is specified for the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). The profile itself contributes a parting line located away from the sealing surface and lower compressive load required to achieve a seal.
