Overview
The TFR Series Female Run Tee is a three-port pipe fitting designed to provide a female threaded connection at the run position of a tee.
The fitting combines one female threaded run port with two male threaded ports, providing a compact three-way connection for threaded instrumentation and process piping systems.
NPT is the primary thread configuration. Selected ISO/BSP tapered-thread versions are also available.
Key Features
- Female threaded connection at the run position
- Two male threaded connections
- Three-port tee configuration
- NPT configurations from 1/16 to 1 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 NPT configurations in 316 stainless steel:
NPT Size | Working Pressure |
|---|---|
1/16 in. | 9,200 psi / 633 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. | 5,300 psi / 365 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 thread configurations include:
- NPT
- ISO/BSP Tapered
All three ports use the same thread family in the catalogue configurations shown. The exact thread standard and size should be specified when ordering.
Female Run Configuration
The term Female Run Tee identifies the position of the female connection within the tee.
The TFR configuration provides:
- One female threaded port at the run position
- Two male threaded ports
- A three-way flow path arranged in a tee configuration
Port orientation is important when selecting mixed male/female tees. A Female Run Tee should not be assumed interchangeable with a Female Branch Tee, Male Run Tee or Male Branch Tee.
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.
The gender, thread standard and size of each connection should be verified before ordering or installation.
Material
Standard Material: 316 Stainless Steel
TFR Series Female Run Tees are manufactured from 316 stainless steel forgings to ASTM A182.
Forged construction is suitable for the shaped tee body and provides a robust connection for instrumentation, process and industrial fluid applications.
Typical Applications
Female Run Tees are commonly used in:
- Pressure measurement systems
- Valve and manifold connections
- Process piping
- Hydraulic and utility systems
- Test and sampling systems
- Pumps and process equipment
- Industrial fluid distribution systems
Selection & Ordering Information
To specify the required Female Run Tee, provide:
- Thread type
- Thread size
- Required port configuration
- Material
- Required working pressure
- Operating temperature
- Fluid or process medium
- Quantity
Confirm that the required configuration is a Female Run Tee, particularly when replacing another mixed male/female tee configuration.
For non-NPT versions, 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.
