Reducin' Tee Dimensions
A reducing tee branches a smaller line right off a larger run in just one fitting. I tell you what, it's the normal way to take a service connection, instrument line, or lateral off a header without havin' to fab up a reinforced branch.
Sizin' convention.
Reducin' tees are called out run × run × branch, commonly shortened down to run × branch. A 6 × 4 tee has a 6" run and a 4" branch. Dem tables carry outside diameter, inside diameter, and wall thickness for both the run and the branch, plus the R and B center-to-end dimensions.
Why not a weldolet.
A reducing tee is a wrought fitting to ASME B16.9 with a set rating and a full-penetration circumferential weld at both ends. Now, a branch fitting is a mighty fine answer when dat branch is a whole lot smaller than the header, but when dem sizes are closer, the tee is a much simpler part to specify, inspect, and stand behind.
How To Read Dese Dimensions
ASME B16.9 tabulates the reducin' tee by run and branch, and the combinations it covers are the ones listed down below. A run and branch pairin' outside dem tables is a special rather than a stock item, so y'all send us the two sizes and we'll tell you which it is right quick.
- O.D.
- Outside diameterOutside diameter at the weldin' end, matchin' up perfect with the pipe it welds to.
- I.D.
- Inside diameterBore right through the fitting, set by dat wall thickness.
- T
- Wall thicknessNominal wall at the weldin' end, matched to the pipe schedule.
- R
- Center to end, runFrom the intersection of the centerlines to the welding face on either end of the run.
- B
- Center to end, branchFrom the intersection of the centerlines to the welding face on the smaller branch outlet.

Questions Folks Ask Us
How do you specify a reducing tee?
Run size, run size, then branch size, usually written run × branch when you're out in the field. A 6 × 4 reducing tee has a 6" run with a 4" branch outlet. Just give us the schedule and material grade for each end when y'all holler for a quote.
How small a branch can a reducing tee have?
Now dem standard reducing tees cover a wide but finite set of run and branch combinations, and the tables up above list the ones made to the standard. Once dat branch gets mighty small compared to the run, a branch outlet fitting is usually the more practical answer, I tell you what.
What are the R and B dimensions?
They're the center-to-end dimensions for the run and the branch, measured right from where the centerlines meet out to each weldin' face. Both are listed by size and schedule in the tables up above.
