Nibco Reducing Tee Copper Fitting

This Nibco 611RR reducing tee connects three copper tubes using sweat cup joints. The fitting is made from wrot copper and is rated for potable water systems. It provides a 1-1/4 inch branch with two 1 inch outlets in a single tee body. The component is supplied new and ready for installation.

Suits Plumbers Joining Unequal Copper Lines

Installers who need to step down from a 1-1/4 inch main line to two 1 inch branches will find this tee matches the required tube sizes. It is not intended for press-fit, compression or threaded connections. Builders working with different tube diameters or alternative joining methods should select a different fitting type.

Handles Potable Water Distribution Duties

The copper construction resists corrosion in standard potable water service. Sweat joints form permanent, leak-free seals when correctly soldered. The tee cannot be disassembled once installed and does not suit systems requiring frequent reconfiguration or repair access.

Questions about this item

What copper tube sizes must I already have to solder this reducing tee?

The tee accepts 1-1/4 in copper tube on the run and 1 in copper tube on both the branch and the opposite run end.

Will this fitting join directly to the 1 in copper lines already in my system?

Yes, both 1 in outlets are cup connections sized for 1-1/8 in tube outer diameter, matching standard 1 in copper pipe.

How can I confirm the joints are sound after sweating the tee?

Pressurise the line and inspect each soldered cup for leaks; a dry joint indicates a proper seal.
