Abstract

The connector (11) is for securing to a flat radiator (20) and has a cylindrical tube coupling end (11) parallel to one radiator surface and consists of low-carbon steel to permit pressure welding to the radiator. A prepared short length of steel bar is upset and pressed to form a cylindrical part-cavity. A following pressing forms a shorter, e.g. cubic piece, with the cavity dimension maintained and surrounded by an upward projecting socket collar. The piece is subsequently deformed to deepen the cavity, lengthen the collar to form the end, and to increase the width of the square section lower part to the desired spanner width. One face of the lower part is recessed by machining to break through into the cavity, at the same time producing a projecting annular rim suitable for pressure welding.
