Copper reducing tee for potable water

The NIBCO 9102850 is a sweat fitting tee designed for potable water systems. It connects three copper tubes using cup connections on all sides. The branch reduces from two 2-inch runs to a 1-1/4-inch outlet. Wrot copper construction provides corrosion resistance for plumbing installations.

Sweat joint constraints and flow impact

Each cup connection requires soldering to the corresponding copper tube outer diameter. The 2-1/8-inch run ends and 1-3/8-inch branch end dictate the tube sizes used. Reducing the branch diameter increases velocity and pressure drop at that outlet. Installers must account for fitting length and solder depth when cutting tube.

Reducing branch size determines fit

The 1-1/4-inch nominal branch size is the single specification that decides if this tee matches the piping plan. A different branch size requires a different fitting. Verify the nominal copper tube size for the branch line before purchasing. This tee serves only that specific reduction.

Questions about this item

Should I choose the 2" x 2" x 1-1/4" reducing tee or a straight tee for my project?

Choose this reducing tee when you need to branch from a 2-inch main line down to a 1-1/4-inch line; a straight tee keeps all three outlets at the same size.

How does the 2-inch and 1-1/4-inch copper tube sizing affect flow in a real installation?

The 2-inch run handles high-volume supply while the 1-1/4-inch branch feeds smaller fixtures without needing a separate reducer fitting.

What does the sweat cup connection mean for joining this wrot copper tee?

Each cup slides over the matching copper tube and is soldered, creating a permanent, leak-resistant joint for potable water systems.
