A branch tee is a T‑shaped pipe fitting with three openings — one on each end of the run and one in the middle at a 90° angle. It allows fluid to flow straight through the main line while a portion is diverted into a branch connection. This makes it one of the most essential fittings for building distribution networks, instrument lines, and process piping systems.
At SS Flow Control, we manufacture branch tees in stainless steel 304, 316, and 316L, so they resist corrosion, withstand high temperatures, and maintain their strength in harsh environments — oil and gas, chemical processing, water treatment, food and beverage, and pharmaceutical industries. Stainless steel is the standard when reliability and long service life are critical.
Key facts
- T‑shaped fitting with one run and one 90° branch outlet
- Available as equal tee (all three openings same size) or reducing tee (branch smaller)
- Standard sizes 1/8" to 4" (DN6 to DN100), custom sizes on request
- Every branch tee is checked for thread fit and pressure rating before shipping
Branch Tee vs. Standard Tee — What's the Difference?
In practice, a branch tee and a standard tee often refer to the same fitting. However, the term "branch tee" is commonly used when the branch outlet is of a smaller diameter than the main run — what is technically called a reducing tee. An equal tee has all three openings the same size. At SS Flow Control, we manufacture both equal and reducing branch tees to match your exact flow distribution needs.
Tell us your main pipe size, branch size, working pressure, temperature, and the fluid running through the line, and our team will help you select the right branch tee — whether you need one piece for a repair or a bulk order for a new installation.
