Overview
The UE Series 90° Double Ferrule Union Elbow provides a 90-degree connection between two tubes of the same outside diameter. Double ferrule tube connections at both ends allow the tubing direction to be changed without requiring an intermediate threaded connection.
Fractional and metric tube sizes are available for instrumentation, process control, sampling, testing and other industrial fluid systems.
Key Features
- Double ferrule tube connections at both ends
- 90° equal-size tube-to-tube configuration
- Fractional and metric tube-size options
- No pipe-thread connection required
- 316 stainless steel as the standard material
- Special-alloy options for project requirements
- Suitable for directional changes in instrumentation and industrial tubing systems

Tube Size Options
UE Series Union Elbows are available for fractional and metric tubing. Each standard UE configuration connects two tubes of the same outside diameter while changing the tubing direction by 90 degrees.
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 Elbow 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
90° Double Ferrule Union Elbows are commonly used for:
- Process-control lines
- Sampling and test systems
- Measurement and monitoring systems
- Hydraulic and industrial fluid systems
- 90° directional changes in tube runs
Selection & Ordering Information
To specify the required Union Elbow, 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..
