DS 14-12 belongs to the Straight reducing coupling (pipe-pipe) family in DICSA’s DIN 2353 Pipe fittings technical documentation.
The DIN 2353 catalog identifies the tube-side size and series separately from any stud thread. Straight, elbow and tee arrangements describe the connection layout; the dimensional drawing identifies the adjoining interfaces and installation space.
The catalog groups this component under Straight couplings. The model table specifies ØD1, ØD2, Serie, Working (bar), L, L1, HEX 1, HEX 2, HEX 3. These designations should be read together with the dimensional drawing when matching the component to the adjoining tube, fitting or mounting arrangement.
