ABSTRACT:
A method and tool for installing a baffle in a tubular member, such as a heat exchanger manifold. The method and tool are adapted to use a baffle having a closed base that acts to obstruct the flow of a fluid within the tubular member, and further having a sidewall extending axially from the perimeter of the base so as to form a recess in the baffle. The tool is generally composed of a sleeve having an elastically and radially deformable end, such as a number of cantilevered members adapted to be elastically bent radially outward. Radially outward deformation of the sleeve enables the sleeve to securely grip the baffle, maintain the orientation of the baffle during its insertion into the tubular member, and then plastically deform the sidewalls of the baffle in order to secure the baffle to the wall of the tubular member.
