Overview
The UT Series Double Ferrule Union Tee provides a three-way connection between tubes of the same outside diameter. Double ferrule tube connections on all three ends allow an equal-size branch to be added to a tube run without requiring threaded intermediate connections.
Fractional and metric tube sizes are available for instrumentation, process control, sampling, testing and other industrial fluid systems.
Key Features
- Three double ferrule tube connections
- Equal-size tee configuration
- Fractional and metric tube-size options
- No pipe-thread connections required
- 316 stainless steel as the standard material
- Special-alloy options for project requirements
- Suitable for branching instrumentation and industrial tubing lines

Tube Size Options
UT Series Union Tees are available for fractional and metric tubing. Each standard UT configuration connects three tubes of the same outside diameter in an equal tee arrangement.
Select the required tube O.D. in fractional or metric sizing.
Size & Configuration Information
Dimensions and ordering numbers vary by tube O.D. Configuration-specific dimensional information can be provided for quotation and technical review.
Materials
316 stainless steel is the standard material for this series.
For corrosive or special-service requirements, Monel 400, Inconel 625, Super Duplex 2507 and other special alloys are available for applicable project configurations.
Specify the required material grade together with the tube size and quantity when requesting a quotation.
Pressure & Temperature Considerations
Allowable working pressure depends on the complete tube-fitting system rather than the Union Tee body alone. Relevant factors include tubing material, tube O.D., wall thickness and operating temperature.
The pressure capability of the lowest-rated component in the assembled system should be considered when determining allowable working pressure.
For pressure- or temperature-sensitive applications, provide the tubing specification, material, operating pressure and operating temperature for review.
Typical Applications
Double Ferrule Union Tees are commonly used for:
- Instrument and analyzer tubing
- Process-control lines
- Measurement and monitoring systems
- Hydraulic and industrial fluid systems
- Equal-size branch connections in tubing assemblies
Selection & Ordering Information
To specify the required Union Tee, provide:
- Tube O.D. — fractional or metric
- Material
- Operating pressure and temperature
- Quantity
Existing part numbers, drawings, specifications or product references can also be used for product matching and quotation review.
