Q-463 BUNA 70 Q RING

Ordered as QH70463, this is an AS568-463 black Buna-N (Nitrile) 70 Shore A Quad-Ring built to an inside diameter of 16.955 in (430.66 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 17.505 in (444.63 mm). The quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

As a material, Buna-N (Nitrile) delivers reliable performance in both static and dynamic service, strong abrasion and tear resistance. The compound resists petroleum-based oils, propane and butane, and water. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). The profile itself contributes resistance to the spiral twisting that defeats round-section rings and lower compressive load required to achieve a seal.

Typical settings include construction equipment, agricultural equipment, and general industrial maintenance.

This item is sold individually under part number QH70463. Nominal inside diameter is listed as 17 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
