The G Series rotary unions have been expecially developed in order to manage the flow of high temperature liquids.
The special bellow, specifically designed in stainless steel for this very application, guarantees a long life for the unions, without problems even in case of very demanding applications.
The graphite micro-lapped seals, thanks to the flexibility of the bellow, perfectly match the case-hardened steel seal of the rotating shaft. The two sintered graphite bushings allow a perfect axial rotation without any problems.
NPT threads and other threads are available.
