Q-462 BUNA 70 Q RING

The QH70462 is an AS568-462 black Buna-N (Nitrile) 70 Shore A Quad-Ring measuring an inside diameter of 16.455 in (417.96 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 17.005 in (431.93 mm). This quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

As a material, Buna-N (Nitrile) offers low compression set under sustained load, strong abrasion and tear resistance. The material holds up against many alcohols, water, and petroleum-based oils. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in ketones or automotive brake fluid. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and lower compressive load required to achieve a seal.

Common environments for this compound include fluid power, hydraulic and pneumatic systems, and general industrial maintenance.

Reference part number QH70462 when ordering; the item is sold individually. Unit weight is approximately 61.778 g and nominal inside diameter is listed as 16 1/2 inch. Review your operating media and conditions against this specification before installation.
