    I managed to break off the elbow connecting one of my batteries to the breather tube.

    Removing the broken part of the elbow was easy but I was not sure where to get a replacement part.

    Then I had a bright idea - why not use the same size (almost) elbow used in windscreen washer circuits.

    Now i know why not, I found a small puddle of blue goo on the bottom of the battery box and a small section of the blue elbow still attached to the breather pipe, which was also lying in the floor of the battery box.

    The problem is that the windscreen washer parts are not suitable for carrying acids.

    Car part shop - no luck locally.

    Internet - no luck there so far but I do not really know what words to use for a Google search.

    So where do I get a replacement elbow?

    Could you make/alter a metal fitting? Find something with a thread so you can screw rather than glue. Steel rather than copper or aluminium. Thats the direction I`d be thinking.

    no idea what you could use but i imagine it must be a brittle plastic...like the stuff biro pens are made of....nylon type plastic will melt as you found out:Sad:

    is there a car re-cycling yard near you?
    they may give you one off an old battery.

    Hi,

    A good alternative might be a silicone rubber 'noodle' tube, used to line the alloy noodles of the brakes used on mountain bikes. They are quite stiff, and I think silicone would not be affected by battery acid.

    They only cost a few pence.

    Good luck.

    Try asking at a battery stockist, even if they don't sell what you want the may have a suitable replacement on a scrap battery.

    To be honest i think most of the poly fitting you can get from anyone who sells aquariums would do. dosen't really react with poly products, although over a period of time can darken and become brittle.
    Its all i used when i worked in a lab( Not stuff to mess about with though)

    I always thought the pipe was to vent hydrogen not acid? :Eeek:

    That's true but it is obvious that a small amount of acidic vapour got carried to the elbow which is only a cm or so above the top of the electrolyte.

    I just dumped our Leisure Battery at local Tip. You may find one there. My new Leisure Battery doesnt seem to be vented, and I know from earlier today that the fuse gives a good spark when it blows. Does anyone know if vents can be fitted retro or should I change the battery. The Battery box is under the floor and has vent holes in it (the old battery was vented but not to outside, just into Battery box!)

    It is , but when the battery is being heavily or discharged the bubbles of gas carry little spots af acid with them.
