Abstract
An apparatus and method for cleaning the tubes of a heat exchanger of a type having at least one header that defines a manifold chamber having a plurality of tubes extending therefrom, the tubes and the header defining tube openings to provide open communication between the tubes and the manifold chamber, the tube openings defining a peripheral seating surface, there being bores in the header, respective ones of which are in register with respective ones of the tube openings, the apparatus comprising a tubular member having a first end and a second end, the tubular member being dimensioned such that the first end can be received through at least one of the bores, a force transmitting lever assembly connected to the tubular member and operatively connected to the header whereby the tubular member can be urged toward the seating surface of a tube opening in register with a bore through which the tubular member is received, there being a seal formed between the tubular member and the seating surface.
