Abstract
A header cap and the mating surface of a water header are placed in abutting relationship with a seal for forming a layered, contiguous connection. A pressure device is attached in operative association with the header cap for operatively applying a pressure to the header cap. A spring which is received by the pressure device is compressed for applying a constant and unidirectional pressure to the pressure device which, in turn, transmits the constant and unidirectional pressure to the header cap. The connection is finally heated for brazing the header cap and water header together and for forming a seal.
