Nibco, Inc. 611RR Copper Reducing Tee 2 x 1-1/2 x 1-1/2 in

2-inch Reducing Tee for Copper Plumbing

This Nibco 611RR fitting connects a 2-inch copper tube to two 1-1/2-inch branches in potable water systems. It is a wrot copper sweat fitting designed for permanent soldered joints. The reducing tee suits plumbers and DIYers extending or branching existing 2-inch supply lines. Each port uses a cup connection sized for standard copper tube outer diameters.

Verify tube sizes and solder readiness before

Confirm the main line measures 2-1/8 inches outside diameter and both branch lines measure 1-5/8 inches outside diameter. Ensure all copper tubes are clean, deburred and dry before applying flux and solder. The fitting is restricted from sale in certain states, so check local plumbing codes for compliance. No threading or mechanical joints are used with this sweat connection type.

Integrates into copper supply networks by reducing

The tee joins three copper tubes in a single soldered assembly, reducing the main 2-inch line into two 1-1/2-inch branches. It requires a propane or MAPP torch, lead-free solder and flux to complete the joints. Once installed, it provides a permanent, leak-resistant transition without additional adapters or reducers. The wrot copper construction matches the thermal expansion of the surrounding tubing.
