What Is a Pro-Flex CSST Tee?
A Pro-Flex CSST tee is a branch fitting used to divide a gas piping run into multiple directions. The fitting provides two run connections and a third branch or rise connection, allowing gas distribution to multiple portions of the piping system.
Equal-size tees maintain the same nominal tubing size through all three connections, while reducing tees provide a smaller or larger branch where required by the piping layout.
Pro-Flex also offers tee configurations with an NPT connection at the branch, providing a transition point between Pro-Flex CSST and compatible threaded gas piping components.

Understanding Run x Run x Rise
Pro-Flex identifies its tee configurations using a run x run x rise arrangement. The first two dimensions describe the two inline run connections, while the third dimension describes the branch or rise connection.
For example, a 3/4" x 3/4" x 1/2" tee has two 3/4" run connections and a 1/2" branch connection. This configuration allows the installer to continue the larger main run while feeding a smaller downstream branch.

Pro-Flex CSST System Compatibility
The manufacturer's product guide identifies these tee fittings within the Pro-Flex CSST fitting family. Pro-Flex states that its fittings are designed for use with both traditional Pro-Flex Yellow CSST and Flak Jacket arc-resistant CSST.
Always match each fitting connection to the correct tubing size and verify compatibility with the specific Pro-Flex tubing and system components being installed.
Installation & Sizing Considerations
- Select the tee according to the required run x run x rise configuration.
- Verify all Pro-Flex CSST connection sizes before ordering.
- For PFTF models, confirm the required NPT branch size.
- Size the main run and branch piping according to the connected gas loads.
- Use compatible Pro-Flex tubing, fittings, and installation components.
- Follow current Pro-Flex fitting assembly and installation instructions.
- Properly support the connected CSST and piping components.
- Protect CSST where required by the installation and applicable codes.
- Leak-test all completed gas piping connections according to applicable requirements.
- Installation should be completed by qualified gas-piping personnel.
Pro-Flex Fitting Installation
Pro-Flex describes its CSST fitting installation process as stripping the tubing jacket, positioning the retainer, slide ring and O-ring in the specified tubing valleys, and tightening the fitting according to manufacturer instructions.
Always use the current Pro-Flex installation instructions for complete preparation, assembly, tightening, protection, bonding, inspection, and testing requirements.

Frequently Asked Questions
What is a Pro-Flex CSST tee used for?
A Pro-Flex tee creates a branch connection within a CSST gas piping system, allowing one gas piping run to supply multiple downstream runs.
What does run x run x rise mean?
The first two dimensions identify the inline run connections, while the third dimension identifies the branch or rise connection.
What is the difference between PFTE and PFTF tees?
PFTE models use Pro-Flex connections for the tee configuration, while PFTF models incorporate an NPT connection at the branch.
What is the PFTE-BBB6 configuration?
PFTE-BBB6 is a 1/2" x 1/2" x 1/2" equal Pro-Flex tee.
What is the PFTE-BBC6 bullhead tee configuration?
PFTE-BBC6 is a 1/2" x 1/2" x 3/4" Pro-Flex bullhead tee.
Which model provides a 1" x 1" x 1/2" connection?
PFTE-DDB6 provides a 1" x 1" run with a 1/2" Pro-Flex branch.
Which model provides a 1" x 1" x 3/4" connection?
PFTE-DDC6 provides a 1" x 1" run with a 3/4" Pro-Flex branch.
Which tee provides a 3/4" NPT branch?
PFTF-CCC6 provides 3/4" PF x 3/4" PF x 3/4" NPT connections.
Can reducing tees be used to supply a smaller gas branch?
Reducing tee configurations provide different run and branch sizes. The complete gas piping system must still be sized according to the required gas load, pressure, piping length, and applicable installation requirements.
Who should install Pro-Flex CSST tees?
CSST gas piping fittings should be installed by qualified personnel according to current Pro-Flex installation instructions and applicable fuel-gas codes.
