A system for brazing together a fitting and tube while in a vertical position. A portion of the interior of the brazing alloy reservoir in the fitting is contaminated with a film of material such as aluminum before the brazing alloy ring is inserted in the reservoir. At the site, the tube is inserted in the fitting to which heat is then applied. Since the contaminant prevents the melted brazing alloy from adhering to a portion of the reservoir interior, the alloy is forced upwardly and downwardly into the annular gaps between the tube and fitting, into which it continues to be drawn by capillary action. |
