Part number HQ4334 is an AS568-334 black Buna-N (Nitrile) 70 Shore A Quad-Ring built to an inside diameter of 2.6 in (66.04 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.02 in (76.71 mm). A quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

This material stands up to petroleum-based oils, greases and lubricants, and water. Buna-N (Nitrile) delivers strong abrasion and tear resistance, reliable performance in both static and dynamic service. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ketones or automotive brake fluid. The profile itself contributes a parting line located away from the sealing surface and lower compressive load required to achieve a seal.
