ABSTRACT:
A braided hose which has a frost-free socket joint made by placing a ring of brazing material above the joint and heating the joint below the ring. This way, the brazing material flows into the joint so that its external and exposed edge of the joint is completely filled. If the capillary action of the molten solder is incomplete, any voids in the joint are exposed to the interior of the hose and not to the atmosphere. The socket is very shallow, in the order of one-half to one convolution of the hose.
