The rotary unions of the N series are divided into two categories:
• FOR STEAM: the standard supply foresees that the rotating part and the closing flange are in stainless steel.
• FOR DIATHERMIC OIL: the standard supply foresees that the constructive material is entirely in cast iron.
The spherical seal and the bearings are made of impregnated graphite; the threads are cylindrical GAS for the fixed part (body) and conical GAS for the rotating part (rotor).
