Q-364 BUNA 70 Q RING

The QH70364 is an AS568-364 black Buna-N (Nitrile) 70 Shore A Quad-Ring with an inside diameter of 6.725 in (170.82 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 7.145 in (181.48 mm). This quad-ring provides a dual sealing band on each contact face for improved reliability.

It resists many alcohols, propane and butane, and petroleum-based oils. Buna-N (Nitrile) offers strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to ketones or polar solvents will shorten service life. The profile itself contributes a parting line located away from the sealing surface and lower compressive load required to achieve a seal.

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

This item is sold individually under part number QH70364. Unit weight is approximately 15.225 g. Review your operating media and conditions against this specification before installation.
