All of our Basic Central Vacuum Hoses fit into inlets with an inch and half diameter. They are all lightweight, crushproof, and have 27% more air flow than older vacuum hoses. All basic vacuum hoses work by plugging in the vacuum hose end into the inlet on the wall and the suction starts right away (there is no on/off switch on the vacuum hose handle). Our basic vacuum hoses come in many lengths, including: 25ft, 30ft, 35ft, and 50ft. Choose the basic vacuum hose you would like to purchase from the drop down menu below.
