    I have some tylene hoses semi-permanent in my garden to ease irrigation.
    To winter-proof them (ie prevent frost damage), the hoses and pipes need to be drained, but the lowest point is below the house.
    With this thing, I can use compressed air to empty all tubes, hoses, connectors, valves in one go.
    It fits 13mm or 1/2" tubing on one end (to fit to Gardena coupling, for example) and a car valve / tyre pump on the other end.

    Put the tube/hose in a cup of hot water first, to make it more flexible.

    Tested to 3 bar.
