SE Series 2-Passage Rotary Unions & Joints
DSTI 2-passage SE Series rotary unions are designed for applications with high pressure requirements and tight spatial constraints and feature two independent flow passages.
SE 2-passage models come standard with threaded connections on the sides of the shaft and housing. Models are also available with optional shaft O-ring glands for face/flush mounting (which must be specified when ordering).
Need to combine fluid with electrical power, signal and/or data transfer? No problem. The SE 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.
- 1Side Threaded Connections (Standard)
- 2Optional Face/Flush Mounting Connections (Not Threaded)
- 3Threaded 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.
