Description
Stainless Press Reducing Tee (P x FPT)
Merit Stainless Press Reducing Tees (P x FPT) are designed to create a 90-degree branch connection while transitioning from a stainless steel press piping run to a female threaded branch connection. The fitting combines press connectivity with a reducing FPT outlet in a single compact tee.
Merit Stainless Steel Press Fittings are designed for use with Schedule 5 or Schedule 10 Type 304/304L or 316/316L stainless steel pipe conforming to ASTM A-312. The stated working pressure range is from full vacuum to 300 PSI (20.7 bar) on Schedule 5 and Schedule 10 stainless steel pipe.

P x FPT Reducing Tee Design
A P x FPT reducing tee provides press connections through the main run while adding a female threaded branch connection at 90 degrees.
This configuration allows a compatible male-threaded valve, instrument, adapter, nipple, or other component to connect directly to the branch without adding a separate press-to-thread adapter.
The reducing arrangement also allows the threaded branch to use a different nominal size from the main press piping run.
Why Choose a P x FPT Reducing Tee?
Press-to-Thread Transition
- Press connections maintain the stainless piping run
- Female threaded branch accepts compatible male threads
- Creates a 90-degree threaded takeoff
- Can eliminate a separate threaded adapter
- Useful for valves, instruments, and equipment connections
Reducing Branch Configuration
- Allows different main-run and branch sizes
- Combines tee, reducer, and threaded transition functions
- Can reduce the number of separate fittings required
- Useful in compact mechanical assemblies
- Simplifies mixed press-and-thread piping layouts

Installation & Selection Guidance
- Confirm all required run and branch sizes before ordering.
- Verify the press run size and female threaded branch size for the selected tee.
- Use only compatible Schedule 5 or Schedule 10 stainless steel pipe on the press connections.
- Confirm pipe is Type 304/304L or 316/316L stainless steel as required.
- Verify that the stainless steel pipe conforms to ASTM A-312.
- Confirm the female threaded branch is compatible with the mating male-threaded component.
- Inspect and properly prepare press-connected pipe ends before installation.
- Insert the pipe to the required depth before pressing.
- Use compatible press tooling and jaws approved for the Merit Stainless Press system.
- Use an appropriate thread sealant on the FPT branch for the system media, pressure, and temperature.
- Apply thread sealant according to the sealant manufacturer's instructions.
- Avoid excessive torque on the threaded branch connection.
- Confirm tee orientation and branch direction before completing the press connections.
- Confirm system media compatibility using the Merit chemical compatibility chart.
- Verify that the full-vacuum-to-300-PSI working range is suitable for the intended system.
- Review applicable approvals and submittal requirements before specifying the fitting.

Frequently Asked Questions
What does P x FPT mean?
P refers to the press connection, while FPT refers to a female pipe thread connection. This tee uses press connections through the run and a female threaded branch.
What is this reducing tee used for?
It is used to create a reduced female-threaded branch from a compatible stainless steel press piping run.
Can a male-threaded valve connect directly to the branch?
Yes, provided the male thread size and thread form are compatible with the female threaded branch and the component is suitable for the system.
How is this different from an all-press reducing tee?
An all-press reducing tee uses press connections at all three openings. This fitting provides a female threaded branch instead of a press branch connection.
What pipe is this fitting designed for?
Merit identifies the Stainless Press system for Schedule 5 or Schedule 10 Type 304/304L or 316/316L stainless steel pipe conforming to ASTM A-312.
What is the working pressure range?
The stated working pressure range is from full vacuum to 300 PSI (20.7 bar) on compatible Schedule 5 and Schedule 10 stainless steel pipe.
Does the press portion require welding?
No fitting weld is required for the press connections. The fitting is mechanically pressed onto compatible stainless steel pipe using the appropriate tooling.
What pipe schedules are compatible?
The supplied information identifies Schedule 5 and Schedule 10 stainless steel pipe.
Where can I verify the exact run and FPT branch sizes?
Use the Merit Stainless Press Dimensional Catalog in the Product Documents section above.
Where can I check chemical compatibility?
Use the Merit Stainless Press Chemical Compatibility Chart in the Product Documents section above.
Where can I find compatible press tooling?
