ABSTRACT:
A bellows has a first portion that is formed with a hollow protrusion and can be actuated and a second portion formed with an annular wall defining an opening. The hollow protrusion fits within the opening. Actuation of the first portion causes a fluid to flow through the hollow protrusion and opening, and the fluid tends to force the protrusion against the annular wall. In another embodiment, the first and second portions are sealed along planer front end rear walls. A nut is provided having teeth for clamping the device to an air tube. The device can be used in hot tubs, saunas, on vending machines, and has many medical uses.
