LT Series 4-Passage Rotary Unions & Joints
The 4-passage LT Series rotary unions feature four independent flow passages and a compact, lightweight all-aluminum construction.
LT 4-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 LT Series rotary unions are designed to integrate directly with our standard electrical slip rings. See options.

*Use of liquid media with LT Series rotary unions should be considered at the customer's own risk. 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.
