ABSTRACT:
A method for producing a copper brazed hose coupling assembly from a plurality of members in which one of the members is electroplated with copper is provided. A stem member is press fitted to a collet member and subsequently brazed together in a furnace. The copper material being located adjacent the joint between the stem and collet members results in a high quality braze joint to be provided with a predetermined minimum amount of copper. The copper brazed hose coupling is particularly suited for use in a fluid operated system.
