Abstract
A method of locking an established flared or compression fitting by the use of a form consisting of two identical halves shaped and dimensioned freely to accommodate the fitting and adjacent portions of the tubing ends. Supplies of the two components forming, when mixed, a volume of epoxy resin such that if contained within the form when assembled about a fitting, overfills the form. Approximately one half of the resin is poured into each of the two halves which are then assembled about the fitting with excess resin extruded at least through the ends of the form. When the resin is hardened it locks the fitting and the peripheral nut surfaces preventing the loosening of the fitting nuts.
