Rotary Unions GPS Series
GPS Series Rotary Unions & Joints
*Some applications using Chemical or water-based media may require alternative sealing materials. Applications above 220° F (105° C) require alternative seal materials. Please consult with DSTI for approval.

7,500 PSI [515 BAR]The GPS Series rotary unions are available in 2, 3, 4, 6, 8, 10 and 12 passage models. These general-purpose, corrosion-resistant rotary unions feature specialized sealing technology suitable for vacuum and bidirectional pressures and independent flow passages capable of transferring different media types simultaneously.
The stainless steel construction is suitable for hydraulic, pneumatic, coolant, water, and other corrosive media types. Carbon steel models are available for applications that do not require water or corrosive media transfer (see GP Series).
GPS models with 2, 3, 4, 6 or 8 flow passages come standard with NPT threaded shaft connections and O-ring face seal glands for flush mounting the union to an interface.
GPS models with 10 and 12 flow passages come standard with NPT threaded connections on the sides of the shaft and housing. Optional O-ring face seal glands are available 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 GPS Series rotary unions are designed to integrate directly with our standard electrical slip rings. See options.

*Some applications using Chemical or water-based media may require alternative sealing materials. Applications above 220° F (105° C) require alternative seal materials. Please consult with DSTI for approval. All values listed under Technical Specifications are dependent on a combination of all application parameters. Please note operational life is dependent upon both rotational speed and duty cycle. Contact DSTI if your application requires operating close to the maximum rotational speed with a continuous duty cycle. Applications with temperatures above 220° F (105° C) require alternative seal materials. The use of Water media with temperatures above 212° F (100° C) require alternative seal materials. Please consult with DSTI regarding your specific application requirements.
