    Need Brass Nut for pipe fitting

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi all, I have a copper tube from the boiler to the flow meter on my FAEMA Due that has a split nut on the boiler end. I had tightened it too much...

    I cant see the fitting on Coffeeparts. I am happy to cut the copper and re-flare the tube and just use a new brass nut.

    I will try Pedro on Monday but anyone have any ideas for a nut?

    Cheers

    Have you tried the plumbing section of Bunnings? They seem to have heaps of that kinds of stuff. Not sure if they'll have the size you need though.

    I have from Coffeeparts ordered a 3/8th BSP suitable nut that looks ok. I havent tried Bunnings...not sure if they run as small as 3/8th.

    Cheers

    Hey ozscott,
    You can try ebay, as there are some nuts and other plumbing type equipment.
    Alternatively, I see you are in Brisbane, you can try Anzor, they are in Acacia Ridge (just google Anzor, they have an online product listing).

    Hi good people. The pipe was a bit old and brittle to reflare and split...who would have thought after 35 odd years! I dont think i can purchase the whole pipe and fittings already made up ??...so does anyone know a good place in or around Brisbane where i can get a new pipe bent up? (I have the fitting for the flow metre end from the old pipe that can be cut off and braised onto the new pipe and i have a new nut for the boiler end. Pic of the good pipe from the left group attached.

    Cheers

    Any refrigeration mechanic would totally at home with this work, and a lot plumbers with oxy gear in their trucks.

    Or buy yourself a mapp gas torch and some 20% silver solder and do the job yourself. Ideally with brass you should a SS flux. Rothenberger make a good tool,

    1/4 inch copper can be bent by hand using any available object as a former provided the copper is well annealed before bending. To anneal the tube heat to a cherry red and allow to cool naturally.

    Best of luck

    It's always a good idea to anneal pipe prior to flaring.

    Looking at the image, I'd be tempted to aneal the entire pipe, trim the end and flare again, with a little careful reshaping it may be OK.
