Overview
The TFC Series Female Cross is a four-port pipe fitting designed to create a compact four-way junction in threaded fluid systems.
All four ports are female threaded and arranged in a cross configuration, providing two opposing connections along each axis. This allows four male-threaded components or pipe connections to be connected through a single fitting body.
NPT is the primary thread configuration. Selected ISO/BSP tapered-thread versions are also available for different piping and equipment requirements.
Key Features
- Four female threaded ports
- Compact four-way cross configuration
- Female NPT sizes from 1/16 to 1 1/2 in.
- Selected ISO/BSP tapered configurations available
- NPT threads based on ASME B1.20.1
- 316 stainless steel as the standard material
- Shaped body manufactured from forging
- Suitable for instrumentation, process and industrial fluid systems

NPT Sizes & Working Pressure
For equal-size Female NPT configurations in 316 stainless steel:
NPT Size | Working Pressure |
|---|---|
1/16 in. | 6,700 psi / 460 bar |
1/8 in. | 6,200 psi / 427 bar |
1/4 in. | 7,200 psi / 496 bar |
3/8 in. | 5,600 psi / 385 bar |
1/2 in. | 5,600 psi / 385 bar |
3/4 in. | 5,100 psi / 351 bar |
1 in. | 6,400 psi / 440 bar |
1 1/4 in. | 3,100 psi / 213 bar |
1 1/2 in. | 5,100 psi / 351 bar |
Working-pressure ratings shown above apply to the listed 316 stainless steel configurations. The allowable working pressure of a complete system is limited by its lowest-rated component and applicable operating conditions.
Thread Configurations
Available configurations include:
- Female NPT × Female NPT × Female NPT × Female NPT
- Female ISO/BSP Tapered × Female ISO/BSP Tapered × Female ISO/BSP Tapered × Female ISO/BSP Tapered
All four ports use the same thread family in the catalogue configurations shown.
Four-Port Configuration
The Female Cross provides four female threaded connections arranged at 90° to adjacent ports.
The four-port configuration provides:
- Two opposing female ports along one axis
- Two opposing female ports along the perpendicular axis
- A single compact junction for four male-threaded connections
This configuration differs from a Female Tee, which provides three ports rather than four.
Thread & Sealing Considerations
NPT is a tapered pipe thread. Sealing is developed through thread engagement together with a thread-sealing method appropriate for the fluid, temperature and operating conditions.
ISO/BSP tapered threads also use tapered-thread engagement but should not be assumed interchangeable with NPT. Thread form, pitch and dimensional standard must match the mating connection.
Thread standard and size should be verified for all four ports before ordering or installation.
Material
Standard Material: 316 Stainless Steel
TFC Series Female Crosses are manufactured from 316 stainless steel forgings to ASTM A182.
Forged construction is suitable for the shaped cross body and provides a robust body configuration for instrumentation, process and industrial fluid applications.
Typical Applications
Female Crosses are commonly used in:
- Instrumentation piping
- Multi-directional pressure lines
- Valve and manifold connections
- Process piping
- Hydraulic and utility systems
- Gauge and instrument connections
- Industrial fluid distribution systems
Selection & Ordering Information
To specify the required Female Cross, provide:
- Thread type
- Thread size
- Material
- Required working pressure
- Operating temperature
- Fluid or process medium
- Quantity
For non-NPT configurations, specify the exact thread standard rather than nominal size alone.
Existing part numbers, drawings, BOMs or product references can also be provided for product matching and quotation review.
