Abstract
A method of sealing a metal retainer to a metal valve body that includes the steps of applying a soldering paste in a predetermined amount to the threads of a threaded retainer and threading the retainer into the threads of a threaded opening in the valve. The retainer is heated to a temperature sufficient to liquefy and disperse the soldering paste into spaces between the threads of the retainer and the threads of the opening in the valve to thereby achieve an adhesive seal.
