Process for forming a connector for tube and pipe fittings

Abstract

Connector that includes a first element having a threaded portion and a rounded end, a second element having an end structured to slidably contact the rounded second end of the first element, and a third element having a conical bore. The second element extends through the conical bore for movement within the conical bore, and a threaded end structured and arranged to mate with the threaded portion of the first element. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

1 . A process of forming a connector comprising: 
 placing a tube in a forming die;    punching the end of the tube in the forming die to form a spherical flare;    positioning the spherical flare against a spherical element;    forming a conical bore in a coupling nut;    placing the coupling nut over the spherical flare and the spherical element;    pivoting the tube within the conical bore; and    tightening a connection between the spherical element and the spherical flare.    
   
   
       2 . The process in accordance with  claim 1 , wherein the spherical flare is a double angle flare.  
   
   
       3 . The process in accordance with  claim 1 , wherein a second tube is slidably extendable into and through the spherical element and slidably extendible into and out of the tube, and the process further comprises telescopically changing a length of the connected tube and second tube.  
   
   
       4 . A process for assembling a connector comprising: 
 forming a rounded end on a first element;    forming a conical bore in a connector nut;    sliding a second element through the conical bore;    forming a flared end on the second element to slidably contact the rounded end;    coupling the connector nut to the first element.
