Product Code:
  • GP-201-12-OF-R.A
General purpose, 12-flow passage, through-bore rotary union with 1/4"-18 NPT housing connections, shaft O-ring face seal glands for flush mounting the union to an interface and carbon steel (black oxide) construction

Availability: 0



The 12-passage, GP Series rotary unions for general-purpose use, feature shaft O-ring face seal glands for flush mounting the union to an interface (the threaded shaft connections are plugged) and NPT thread housing connections.

They feature specialized sealing technology suitable for vacuum and bidirectional pressures and independent flow passages capable of transferring different media types simultaneously.

The carbon steel (black oxide) construction is suitable for air/gas and hydraulic service, in addition to water/glycol and coolant when rust inhibitors are present.
