Chief Steamer 3 hole nozzle. Use this 3 hole nozzle to evenly disperse steam and not blast it when you do not want to. This 3 hole nozzle will prevent the “line pattern effect” that can happen when hot and high pressured steam is directed at a sensitive surface such as leather, vinyl, fabrics or carpeting. This nozzle allows the steam to “bounce” off the walls of the round brush and not hit the surface directly.
