LT Series 24-Passage Rotary Unions & Joints
The 24-passage LT Series rotary unions are designed for air, gas and vacuum use and are ideal for a number of automation and robotic applications. These lightweight, compact rotary unions feature an all-aluminum construction and 24 independent flow passages capable of transferring different types of media simultaneously.
LT 24-passage models come standard with threaded connections on the sides of the shaft and housing. Models are also available with optional shaft O-ring face seal glands for flush mounting the union to an interface (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.

*Minimum torque required to rotate based on zero pressure with Oil/Hydraulic media (or Air/Gas media for SPS Series). 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.
- 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)

*The use of liquid media is not recommended for this product. Please select from one of our other product lines or consult DSTI if your application requires use of liquid media. 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. The use of Water media with temperatures above 212° F (100° C) require alternative seal materials. Please consult with DSTI regarding your specific application requirements.
