The Single-Passage Rotary Union 2300 series, also known as the Single-Passage Rotary Joint, or swivel has been designed to handle higher pressures and low RPM’s. Talco, Inc. offers a unique single-passage rotary union design that incorporates the use of a backup "O" ring and filled Teflon Slipper Seals. This outstanding design results in a prolonged product life and unsurpassed efficiency and reliability over standard "O" ring designs. These Swivel Joints are designed for non-continuous rotation, and are used on Hose Reels and in Car Wash applications.

The recommended operation specifications for the 2300 Series of Single-Passage Rotary Union in American Units is for a Maximum Air Pressure of 200 PSI, a Maximum Vacuum of 28" Hg, Hydraulic Pressure of 5000 PSI, a Maximum Temperature of 400 Degrees Fahrenheit and a Maximum Speed of 400 RPM.

Metric Units would be a Maximum Air Pressure of 14 bar, Maximum Vacuum of 90 kPa, Maximum Hydraulic Pressure of 344 bar, Maximum Temperature of 200 Degrees Celsius and a Maximum Speed of 400 RPM. To prolong the life of the single-passage rotary union, it is recommended to avoid operating at both Maximum Pressure and Maximum Speed at the same time.

All Single-Passage Rotary Unions in the 2300 Series are available with options such as NPT or BSP Thread, Right- or Left-Hand Thread on Rotor and Brass Rotor and Housing. All Stainless Steel Construction, to provide outstanding corrosive deterrent, is available upon request.

Single-passage rotary union models are available in both American and Metric Units in varying sizes and all are CAD and RFQ Interface Enabled. Sizes can be custom made to meet your specifications and requirements.
