Nibco B107600 – Frequently Asked Questions
1) Can the Nibco 711 cast bronze tee be used on potable water lines?
No. The 711 tee is cast from ASTM B584 alloy C84400, and use in U.S. drinking water applications is prohibited after January 3, 2014. Keep it on non-potable work: heating and HVAC piping, fire protection, industrial, and irrigation lines. If the branch you are tying into serves drinking water, you need a lead-free rated fitting instead.
2) What do the three numbers in a Nibco 711 tee size like 2 x 1 x 1-1/2 mean?
They are the run, run, and branch openings, in that order: the first two numbers are the two ends of the straight run through the fitting and the third is the branch takeoff. So 2 x 1 x 1-1/2 gives you a 2 inch inlet, a 1 inch outlet on the run, and a 1-1/2 inch branch. All three are solder cups, so every leg takes copper tube of that nominal size.
3) Does the Nibco 711 tee need to be soldered, or can it be press or threaded?
Solder only. All three openings are C (copper cup) connections sized to slip over copper tube, and the joint is made with solder or brazing filler. There is no thread and no press bead on this fitting. Follow Nibco's copper fittings installation instructions for cleaning, fluxing, and heating the cups.
4) Which Nibco 711 tee do I order to take a 1/2 inch branch off a 1-1/4 inch copper main?
Two options depending on what the run does past the tee. If the run stays full size downstream at 1 inch, order B100950 (1-1/4 x 1/2 x 1). If the run drops to 1/2 inch as well, order B101050 (1-1/4 x 1/2 x 1/2). Both are solder cup on all three openings.
5) Is the Nibco 711 tee cast bronze or wrought copper, and why does that matter?
Cast bronze, made to ASTM B584 alloy C84400. Cast bodies are used for the reducing and odd-combination sizes that are impractical to form from wrought copper tube, which is why the 711 shows up in mixed combinations like 3 x 2-1/2 x 1-1/2. The fitting is also dezincification resistant, which matters on heating and industrial water where a plain brass part can dealloy over time. Material and workmanship follow ASME B16.18.
6) Can I get a Nibco 711 tee with a branch larger than the run?
Yes, the 711 is made in bull-head style combinations where the branch is bigger than the run: 2 x 2 x 3, 2-1/2 x 2-1/2 x 3, and 3 x 3 x 4 all take a branch one size up from the run. That saves building the takeoff out of a coupling and a reducer when you are picking up a larger riser off a smaller main.
7) What size range of Nibco 711 reducing tees is available?
Run sizes run from 1-1/4 inch up to 3 inch, with branch and second-run openings from 1/2 inch to 4 inch. The smallest combination is 1-1/4 x 1/2 x 1/2 and the largest is 3 x 3 x 4. In between you get combinations like 1-1/2 x 1/2 x 1-1/4, 2 x 3/4 x 3/4, 2-1/2 x 1-1/2 x 2, and 3 x 2 x 1-1/2, so most reducing branch takeoffs on a 1-1/4 through 3 inch main can be made with a single fitting.
8) Is a cast bronze 711 tee acceptable in a fire sprinkler copper line?
Fire protection is one of the listed system uses for the 711 tee, along with commercial and residential plumbing, heating, HVAC, industrial, and irrigation. The fitting is built to ASME B16.18 for material and workmanship. For pressure and temperature engineering data on a specific size, work from Nibco's technical data sheets for the 711.
9) Does anything come with the Nibco 711 tee, or do I need to buy solder and flux separately?
The 711 ships as the bare cast bronze fitting. Solder or brazing alloy, flux, emery cloth or a tube brush, and the fitting brush for the cups are all separate. Nothing threads or presses on, so budget for the sweat consumables on every joint, three per tee.
