<p>A method and apparatus for attachment of tubing to gas valves and similar gas extrusions (104) and tubing joints (100, 100A, 100B) are provided. A gas extrusion body portion (106) is provided with a bore (108) for receiving a small diameter, thin wall tube (102). A groove (110, 110A, 110B, 140, 150, 152, 154, 156) is formed around the exterior of the body portion. The tube (102) having an outside diameter less than an inside diameter of the bore (108) and a flanged eyelet (160), is inserted in the bore. Force is applied to the body portion (106) for deforming an area of the body portion near the groove together with the tube (102) to achieve a mechanical bond, providing a gas tight seal.</p> |
