Abstract
A fitting (1) designed for example as a non-return valve (2) has an outer housing (3) having an inner lip seal (7) interacting with a closing element (5), and also an outer annular seal (8). Both the outer housing (3) and the seals (7, 8) are designed as injection moldings. The production of the outer housing with the seals takes place in an injection molding process in which, first of all, the outer housing and, in a second operation, the seals are injection molded appropriate, more than two operations, in particular in the case of more than two injection molding material components, can also be provided. By means of the injection molded seals, the latter are durably and closely bonded to the outer housing (3) resulting in simplifications regarding production technology and design (FIG. 1).
