An ultrasonic surgical instrument assembly including an irrigation sleeve assembly defining a lumen and an ultrasonic tip at least partially disposed within the lumen of the irrigation sleeve. The irrigation sleeve assembly may comprise a hub and an irrigation sleeve coupled to the hub. The irrigation sleeve may comprise an inner sheath and an outer sheath, both extending distally from the hub. The outer sheath may surround at least a portion of the inner sheath to define an irrigation passageway between the outer sheath and the inner sheath configured to deliver irrigation fluid to the surgical site. The distal end of the inner sheath may extend beyond the distal end of the outer sheath. Each of the inner and the outer sheath may be coupled to the hub by an annular sealing member configured to create fluid-tight seal between the hub and the respective inner and outer sheath.
