Abstract
A tubular metal nipple for joining with the end of a copper tube by means of solder to readily produce a reliable joint in refrigeration plumbing system. The nipple has a inner copper sleeve concentrically spaced from the inside wall of a steel outer casing with an impervious intervening layer of brazing material filling the space and bonding the sleeve to the outer casing. The distal end of the sleeve is tapered or flared outwardly to produce an annular solder well when a tube end is inserted into the nipple.
