GP Series 10-Passage Rotary Unions & Joints
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. See options.

*Minimum torque required to rotate based on zero pressure.
- 1Standard Threaded Side Connections (Plugged if O-ring Face Seal Gland Option is Specified)
- 2Optional, Non-threaded O-ring Face Seal Glands for Flush Mounting (Must Be Specified When Ordered)
- 3Threaded, Interface Mounting Holes
*Suitable Water/Glycol or Coolant media must have rust inhibitors present. Oil/Hydraulic media must be petroleum-based. 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. Please consult with DSTI regarding your specific application requirements.
