Overview
The FC Series Double Ferrule Female Connector provides a straight connection between fractional or metric tubing and a male threaded component. The tube end uses a double ferrule tube connection for mechanical gripping and sealing, while the female threaded end connects to instruments, valves, manifolds and other fluid-system components.
Multiple tube sizes and female-thread configurations are available for instrumentation, process control, sampling, testing and other industrial fluid systems.
Key Features
- Double ferrule tube connection for mechanical gripping and sealing
- Straight tube-to-female-thread configuration
- Fractional and metric tube-size options
- Multiple female-thread configurations
- 316 stainless steel as the standard material
- Special-alloy options for project requirements
- Broad size combinations for instrumentation and industrial fluid systems

Connection & Size Options
FC Series Female Connectors are available for fractional and metric tubing with NPT, ISO tapered, ISO parallel and metric 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., female-thread type and thread 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 connection and quantity when requesting a quotation.
Pressure & Temperature Considerations
Allowable working pressure depends on the complete tube-fitting system rather than the Female Connector body alone. Relevant factors include tubing material, tube O.D., wall thickness, operating temperature and the selected threaded connection.
The pressure capability of the lowest-rated component or connection should be considered when determining the allowable system working pressure.
For pressure- or temperature-sensitive applications, provide the tubing specification, material, thread size, operating pressure and operating temperature for review.
Typical Applications
Double Ferrule Female Connectors are commonly used for:
- Pressure and flow measurement connections
- Valve and manifold connections
- Sampling and test systems
- Process-control tubing
- Hydraulic and industrial fluid systems
Selection & Ordering Information
To specify the required Female Connector, provide:
- Tube O.D. — fractional or metric
- Female-thread type
- Thread 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.
