Overview
The FE Series 90° Double Ferrule Male Elbow connects tubing to a female threaded port while changing the flow direction by 90 degrees. One end uses a double ferrule tube connection, while the other provides a female threaded connection.
Fractional and metric tube sizes are available with multiple female-thread configurations and sizes for instrumentation, process control, sampling, testing and other industrial fluid systems.
Key Features
- 90° tube-to-female-thread connection
- Double ferrule tube connection
- Multiple female-thread configurations
- Fractional and metric tube-size options
- Multiple tube O.D. and thread-size combinations
- 316 stainless steel as the standard material
- Special-alloy options for project requirements

Connection & Size Options
FE Series Female Elbows are available for fractional and metric tubing with NPT, ISO tapered and ISO parallel female-thread configurations. Tube O.D., female-thread type and thread size are selected according to the required connection. Available combinations vary by configuration.
Size & Configuration Information
Dimensions and ordering numbers vary by tube O.D. and female NPT size. 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, thread size and quantity when requesting a quotation.
Pressure & Temperature Considerations
Allowable working pressure depends on the complete tube-fitting system rather than the Female Elbow body alone. Relevant factors include tubing material, tube O.D., wall thickness, operating temperature and the female threaded connection.
The pressure capability of the lowest-rated component or connection in the assembled system should be considered when determining allowable working pressure.
For pressure- or temperature-sensitive applications, provide the tubing specification, material, thread size, operating pressure and operating temperature for review.
Typical Applications
90° Double Ferrule Female Elbows are commonly used for:
- Pressure and flow measurement lines
- Valve and manifold connections
- Sampling and test systems
- Process-control tubing
- Connections to male threaded components where tubing direction must change by 90°
Selection & Ordering Information
To specify the required Female Elbow, provide:
- Tube O.D. — fractional or metric
- Female-thread type and size
- Material
- Operating pressure and temperature
- Quantity
Existing part numbers, drawings, specifications or product references can also be used for product matching and quotation review.
