Hose is leaking at the fitting because of a crack in the steel tube, adjacent to the braze on a split flange shoulder.
Cause: Because of the crack is adjacent to the braze and not in the braze, this is a stress failure that could be brought on by a hose that is trying to shorten under pressure, but has insufficient length to do so. Aeroquip has cured dozens of these problems by lengthening the hose assembly or changing the routing to relieve the forces on the fitting.
