STA ESVS 30 belongs to the Welding bulkhead couplings family in DICSA’s DIN 2353 Pipe fittings without nut and ring technical documentation.
The catalog identifies this as a fitting body supplied without the nut and ring. Its tube-side designation and stud or mating thread describe separate interfaces; the complete assembly requires the corresponding connection parts.
The catalog groups this component under Welding nipples. The model table specifies ØD1, Serie, Working, L, L1, ØT. These designations should be read together with the dimensional drawing when matching the component to the adjoining tube, fitting or mounting arrangement.
