Q-034 BUNA 70 Q RING

The QH70034 is an AS568-034 black Buna-N (Nitrile) 70 Shore A Quad-Ring measuring an inside diameter of 2.114 in (53.7 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.254 in (57.25 mm). This quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Buna-N (Nitrile) is specified here for strong abrasion and tear resistance, reliable performance in both static and dynamic service. This material stands up to water, hydraulic fluids, and petroleum-based oils. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). The profile itself contributes a parting line located away from the sealing surface and lower compressive load required to achieve a seal.

Typical settings include hydraulic and pneumatic systems, construction equipment, and general industrial maintenance.

Order part number QH70034, sold individually. Unit weight is approximately 0.601 g and nominal inside diameter is listed as 2 1/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
