CASE 580K SN JJH… brake lines

CaseCI ยท 2012-10-10 06:46

Hi all, trying to fix brakes...not much luck finding a substitute for D136431 hoses. Local hydraulic dealers do not work with those fittings. Does somebody knows which fittings will fit? I guess is NPT 1/4" but not sure at all. Rule is in mm.

    That would be an "inverted flare" fitting. I believe that it would be 1/4". Measure the outside diameter of the tube to be sure. 1/4"=6.35mm It is not a national pipe thread (they have a tapered thread and is measured from the inside diameter of the pipe).

    Last resort. You can always weld the old fittings to a new, standard fitting to attach the hose to.

    Welding old and new fittings together has worked for me several times before with hydraulics. Should work with brake lines to. I would use steel or stainless steel instead of brass welding rods and an acetylene torch if possible. Mig welding also works but you may end up with a pin hole or two and need to add weld to the leaking spots. Clean and sand off all dirt before you start welding. Good luck and let us know how it turns out. Deon
