The GP Series rotary unions are available in 2, 3, 4, 6, 8, 10 and 12 passage models. These general-purpose, multiple-passage rotary unions 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, 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 models with 2, 3, 4, 6 or 8 flow passages come standard with NPT thread shaft connections and O-ring face seal glands for flush mounting the union to an interface. GP models with BSPP thread connections are not available with O-ring face seal glands.

GP models with 10 and 12 flow passages 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 connections on the 10 and 12 flow passage 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. See options.
