Q-460 BUNA 70 Q RING

This quad-ring is supplied in AS568-460 black Buna-N (Nitrile) 70 Shore A built to an inside diameter of 15.475 in (393.07 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 16.025 in (407.04 mm), catalogued under part number QH70460. It seats in a standard o-ring gland while offering improved dynamic performance.

The compound resists greases and lubricants, water, and petroleum-based oils. Buna-N (Nitrile) is valued for low compression set under sustained load and an economical choice for high-volume maintenance programs. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Applications involving strong acids or automotive brake fluid call for a different compound. The profile itself contributes a parting line located away from the sealing surface and lower compressive load required to achieve a seal.

Maintenance and OEM teams specify it across automotive, construction equipment, and fluid power.

This item is sold individually under part number QH70460. Unit weight is approximately 63.65 g and nominal inside diameter is listed as 15 1/2 inch. Review your operating media and conditions against this specification before installation.
