The hose attaches directly to the wand, to do this heat the end of the hose up in a cup of hot water or use a heat gun. Once the hose becomes soft you can slide it up over the base of the wand as far as you can. When the hose cools it will grip on. For wands with a valve you will also need a clamp which can be placed on the hose in front of the clamp bump on the bottom of the wand.
