Q-384 BUNA 70 Q RING

Ordered as QH70384, this is an AS568-384 black Buna-N (Nitrile) 70 Shore A quad profile Quad-Ring built to an inside diameter of 14.975 in (380.37 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 15.395 in (391.03 mm). The quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

Buna-N (Nitrile) is specified here for economical choice for high-volume maintenance programs, strong abrasion and tear resistance. The compound resists water, hydraulic fluids, and greases and lubricants. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to ozone and direct sunlight or polar solvents will shorten service life.

You will find this material specified across hydraulic and pneumatic systems, automotive, and construction equipment.

Reference part number QH70384 when ordering; the item is sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
