GP Series 8-Passage Rotary Unions & Joints
DSTI 8-passage GP Series rotary unions feature specialized seals suitable for vacuum and bidirectional pressures up to 7,500 PSI [515 BAR] and eight independent flow passages.
GP 8-passage models consist of a specialized shaft configuration for easier installation allowing the choice of mounting the shaft connections using the female tapped passages or O-ring glands for face/flush mounting.
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.
*Stainless steel (housing/shaft) material option is recommended for all liquid media applications. 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.
