    Hi all
    I have my Fathers very old Paraffin Blowlamp, which I’ve restored but the only thing I’m stuck with is the rubber washer which goes onto the output put that screws into the body.
    The MM size is 17mm outer and 12mm inner, but I’m struggling to get an imperial washer for it.
    Would you know where I might get one and what imperial size?
    Always grateful for any help
    Cheers
    Glen

    I bought sheets of varying thicknesses of viton from the the 'Bay and cut my own using hollow punches. Alternatively you could contact The Fettlebox.

    For threaded joints like that you might try just sealing the threads with copper slip. I have found that works on Primus type stoves where the burner and meth cup is normally sealed with a compression fibre washer. I have done this several times now by cleaning off the old washer residue and just filling the threads with slip and so far never had a leak. Saves a deal of head scratching over washer sizes and very easy to do. ::Neil::

    Surprised the hell out of me as well. I got seriously frustrated trying to fit a washer on a three leg stove and the new burner washers kept disintegrating on me so I tried with just the copper slip and it worked with a perfect seal. Not used a washer on a burner since and not had any problems. ::Neil::
