Tapered Cuff screws onto Basic Hoses (ones without a switch on the handle). It then fits valves slightly larger than 1.5" diameter such as Filtex metal inlets, some AstroVac, VacuMaid, and others. This cuff will not work with valves having two metal contact points inside the inlet insertion hole. Basic Hoses #302TC and 303TC ship with this cuff included.
