Copper reducing tee for non-potable systems

This cast-bronze reducing tee connects two 1-1/4 inch copper tubes on the run and a 3/4 inch FNPT branch, rated for 351 psi at 200 degrees F. It suits installers working on non-potable water lines who need a sweat-to-threaded transition in a single fitting.

Replaces separate couplings and adapters

Using one tee instead of a straight coupling plus a threaded adapter cuts joint count and potential leak paths. The jump is worth it when space is tight or when the system pressure approaches the 351 psi limit and fewer solder joints are preferred.

Sweat the run ends, thread the branch

Clean the 1-3/8 inch tube ends, apply flux and solder the two cup connections; then tape and tighten the 3/4 inch FNPT branch. The usual problem is overheating the bronze near the threads, which can distort the female thread and cause seepage.

Questions about this item

What copper tube size do the two sweat ends of this 712R tee accept?

Both sweat ends are sized for 1 1/4 inch copper tube, which has a 1 3/8 inch outer diameter.

How is the FNPT branch sealed during installation, and what mistake should be avoided?

Apply thread sealant or tape to the 3/4 inch FNPT threads and tighten without over-torquing, which can crack the cast bronze body.

Will the cast bronze body of this reducing tee need replacement under normal non-potable water service?

Cast bronze resists corrosion in non-potable water, so the body typically lasts the life of the system; only seals or connected components may need service later.
