DetailsThe 4-passage, GP Series rotary unions for general-purpose use, features a unique shaft configuration with threaded NPT connections and an O-ring face seal gland for flush mounting the union to an interface. They 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 prevents corrosion in harsh environments and is ideal for applications transferring water or other corrosive media types.

Torque 1.9 ft-lbs [2.58 Nm] Product Disclaimer Values listed 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.
Value listed for the minimum torque required to rotate is based on zero pressure with oil/hydraulic media. Required torque to rotate may be greater when using other media types or dry running. For specific torque requirements, please contact DSTI to discuss your application.
