ABSTRACT:
An automotive heat exchanger manifold (56) is formed entirely integrally by starting with a cylindrical blank (10) and integrally forming its ends variously into lower end closures or upper end connectors. Specifically, the lower end of blank (10) is impact extruded into a reduced diameter pin (30) which is not only leak tight and seamless, but inserts into a lower resilient mount (16). The upper end of the blank (10) is cold headed into a line connector (54).
