Q-106 BUNA 70 Q RING

Part number QH70106 is an AS568-106 black Buna-N (Nitrile) 70 Shore A Quad-Ring with an inside diameter of 0.174 in (4.42 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.38 in (9.65 mm). A quad-ring provides a dual sealing band on each contact face for improved reliability.

Buna-N (Nitrile) is specified here for strong abrasion and tear resistance, reliable performance in both static and dynamic service. Expect good resistance to greases and lubricants, many alcohols, and hydraulic fluids. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It should not be specified for service in automotive brake fluid or strong acids. The profile itself contributes a parting line located away from the sealing surface and two sealing bands per contact face rather than one.

You will find this material specified across automotive, construction equipment, and general industrial maintenance.
