Description
Stainless Steel Weld Reducing Tee
Stainless Steel Weld Reducing Tees are designed to create a 90° branch connection while reducing from the main run size to a smaller branch size within a compatible stainless steel piping system. The butt weld configuration provides a permanent welded connection with a smooth internal transition for dependable flow control.
Available in Schedule 10 and Schedule 40, these reducing tees are manufactured from stainless steel raw material conforming to ASTM A312 and are produced and tested to recognized ASTM, ASME, ANSI, and MSS standards.
Product Highlights
- Stainless steel butt weld reducing tee fitting

- Raw material conforms to ASTM A312
- Wall thicknesses conform to ANSI B16.9, ANSI B16.28, and MSS SP-43
- Precision-formed butt weld ends for accurate fit-up
- Suitable for permanent welded stainless steel piping systems
- Useful where a smaller branch size is required from a larger main run
- Designed for commercial, industrial, and process piping applications
Reducing Tee Design
A reducing tee creates a 90° branch from the main piping run while transitioning to a smaller branch connection size. This allows a larger main line to feed a smaller branch without requiring a separate reducer immediately after the tee.
The configuration helps simplify piping layouts where branch flow needs to be distributed through a smaller line size.
Butt Weld Construction
Precision-formed butt weld ends support accurate fit-up with compatible stainless steel pipe before welding. Proper installation creates a continuous welded connection between the reducing tee and adjoining piping.
Confirm the run size, branch size, wall thickness, material requirements, and welding procedure before fabrication or installation.

Frequently Asked Questions
What is a reducing tee?
A reducing tee is a three-opening fitting that creates a 90° branch connection with a branch size smaller than the main run size.
How is a reducing tee different from an equal tee?
An equal tee typically uses the same nominal size on the run and branch, while a reducing tee has a smaller branch connection.
What schedules are available?
The supplied product information lists Schedule 10 and Schedule 40 material options.
What connection type is used?
These fittings use butt weld connections for permanent installation in compatible stainless steel piping systems.
What material standard applies to the raw material?
The raw stainless steel material conforms to ASTM A312.
What manufacturing and testing standards apply?
The fittings are manufactured and tested in accordance with ASTM A403 and ASME SA403/SA403M.
What dimensional standards apply?
Applicable wall thicknesses and dimensions conform to ANSI B16.9, ANSI B16.28, and MSS SP-43.
Can a reducing tee eliminate the need for a separate reducer?
In many piping layouts, the smaller branch built into the reducing tee can eliminate the need to install a separate reducer immediately after an equal tee.
Where can I find fitting dimensions?
