摘要

The flange (1) comprises an injectable seal (11b,12b,13b), and is divided in an axial plane of the tube ends (5a,6a,7a). A two component spray part is produced. The injectable seal is made of a hard and a soft plastic component. The flange and the seal are produced in a two-step spray process. The flange comprises two parts, a lower part (1a) and an upper section (1b), with a half shell-like retainer (2a,3a,4a,2b,3b,4b) for the tube ends. An independent claim is also included for a heat exchanger comprising tube ends with two connection pipes, which are received by a flange.
