ABSTRACT:
A method of forming a spray nozzle along a fluid conduit includes forming a hole into a length of tubing and then providing a countersink for the hole. A portion of the tubing is then depressed inwardly along an imaginary line along the tubing outer surface that is parallel to the central tube axis and that passes over the hole. An apparatus for carrying out the method is also disclosed.
