The 10-passage, GP Series rotary unions feature specialized sealing technology suitable for vacuum and bidirectional pressures and ten independent flow passages capable of transferring different media types simultaneously.

The carbon steel (black oxide) construction is suitable for air/gas, coolant, and hydraulic service. Stainless steel models are available to prevent corrosion for use with applications requiring water or corrosive media transfer (see GPS Series).

GP 10-passage models come standard with NPT or BSPP thread connections on the sides of the shaft and housing. Optional O-ring face seal glands are available for both NPT and BSPP thread connection models (must be specified when ordering).

Need to combine fluid with electrical power, signal and/or data transfer? No problem. The GP Series rotary unions are designed to integrate directly with our standard electrical slip rings.
