Qualatex Dual Action Pump features a tapered nozzle for easy inflation of 5", 6", 260Q, 321Q, and 350Q latex balloons. Comes with an improved non-roll structure for better performance. Dual Action pumps air during both the pull and push stroke, making the inflation faster. Though the nozzle is built for 260Q balloons, it also works great for 160Q's, 350Q's, bee bodies, geo blossoms and donuts, regular round balloons, rocket balloons, and a host of other balloons.
