    I've had a regulator just like this laying around for some time now.

    Although mine has a female fitting to the gas bottle.
    What I'm wondering, is there a way to fit a solenoid and needle valve onto the fitting at the bottom as there isn't any threading to it.
    You basically just slide a tube on it.

    Thanks.

    Just fit it inline, use a short stretch of hose and attach it that way.

    Or if the needle valve is the screw on sort just remove the hose tail. Best to fit solenoids inline though, as Garuf said, they are less prone to leaks in my experience when fitted inline than they are fitted directly on.

    What About any back pressure?
    Just worried about when the solenoid kicks in over night, the pressure of gas stopping would push (pop?) the tubing off the regulator... or am I being a worrying little old so an' so?

    The pressure between the needle valve and the solenoid is well under 1 bar, so nowhere near enough to pop the tubing.

    What about between regulator and solenoid?

    So it'll go:

    Regulator__small length of tubing___solenoid(screw type connection)____small length of tubing_____needle valve____tubing to bubble counter etc...

    Have I got it or just given you a head ache?

    You got the order wrong there. It should be regulator___needle valve___solenoid, hence your concerns. Even if you put your needle valve inline rather than directly on the regulator it will still only have about 1-1.7 bars of pressure on it and CO2 tubing tends to go on very tightly.
