Potable Water Copper Tee

The NIBCO 611BH is a sweat fitting tee made from wrot copper for potable water systems. It connects three copper tubes using cup-style joints on every outlet. Plumbers and DIY installers use it to branch a 1-1/4 inch line from a 1 inch main run.

Branch Size Upgrade

This tee replaces a straight coupling or a reducing tee when the branch must be larger than the run. The jump is worth it when the design calls for increased flow capacity on the third leg without reducing the two 1 inch through ports. The bullhead configuration handles that specific layout in a single fitting.

Three Port Capacity

The fitting accepts 1 inch copper tube on side A and side B with a 1-1/8 inch outer diameter on each. Side C takes 1-1/4 inch tube with a 1-3/8 inch outer diameter. It comfortably handles the flow demands of that branch size while the sweat joints provide a permanent seal. It runs out when the system requires a different tube size or a threaded connection.

Questions about this item

What tube outer diameters do the three cup connections of the 611BH bullhead tee accept?

The two 1 in branches take 1 1/8 in OD copper tube and the 1 1/4 in branch takes 1 3/8 in OD copper tube.

How is the Nibco 611BH tee installed and what step is often missed?

Clean each tube end and the cup sockets, apply flux, insert tubes fully, then sweat all three joints with lead-free solder; the step often missed is heating each cup evenly so solder flows completely around the joint.

What maintenance or replacement will the 611BH copper tee need later?

Wrot copper resists corrosion in potable water, so no routine maintenance is required; replacement is only necessary if a joint leaks or the system is re-piped.
