Q-215 BUNA 70 Q RING

Ordered as QH70215, this is an AS568-215 black Buna-N (Nitrile) 70 Shore A Quad-Ring supplied with an inside diameter of 1.046 in (26.57 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.324 in (33.63 mm). The quad-ring provides a dual sealing band on each contact face for improved reliability.

Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. This material stands up to hydraulic fluids, water, and many alcohols. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It should not be specified for service in polar solvents or strong acids. The profile itself contributes lower compressive load required to achieve a seal and two sealing bands per contact face rather than one.

Common environments for this compound include automotive, fluid power, and hydraulic and pneumatic systems.

QH70215 ships individually. Unit weight is approximately 1.1173 g and nominal inside diameter is listed as 1 1/16 inch. Review your operating media and conditions against this specification before installation.
