    why not use a reinfoorcing ring on your coupling

    I could do this, although I haven’t found one yet that will fit inside the throat of the bottle as well as over the lamp rod. To be honest I haven’t tried too hard to find one as it hold fine the way it is at the moment. As I increase pressure I will probably need to do this
