ABSTRACT:
A fitting for a two flat tube serpentine heat exchanger having high burst pressure comprises a header plate with two slots for receiving the flat tubing and a cover plate with a port, a nipple protruding from the port, and a recess surrounding the port and extending over the slots to provide communication between the port and the slots. The plates are formed by extrusion with the appropriate apertures, cut to the desired thickness and the recess is milled out, or the plates and apertures are stamped from sheet stock. The plates are welded together at their common periphery or brazed together at their margins outboard of the recess.
