Q-325 BUNA 70 Q RING

QH70325 is an AS568-325 black Buna-N (Nitrile) 70 Shore A Quad-Ring supplied with an inside diameter of 1.475 in (37.47 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.895 in (48.13 mm). In service, this quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Buna-N (Nitrile) offers reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. It resists water, petroleum-based oils, and propane and butane. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. 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 fluid power, general industrial maintenance, and hydraulic and pneumatic systems.

This item is sold individually under part number QH70325. Unit weight is approximately 3.922 g. Review your operating media and conditions against this specification before installation.
