Nibco, Inc. 611RR 1-1/2 x 3/4 x 1-1/2 Reducing Tee

Copper Reducing Tee for Potable Water Systems

This NIBCO 611RR reducing tee connects three copper tubes in a potable water installation. The fitting uses sweat cup connections on all three ends for soldered joints. It reduces from 1 1/2 inch on the run to 3/4 inch on the branch. The wrot copper construction suits standard plumbing applications.

Sweat Cup Connections and Wrot Copper Build

All three ports feature cup-style sweat connections sized for 1 5/8 inch, 7/8 inch, and 1 5/8 inch outer diameter copper tube respectively. The wrot copper material provides a uniform grain structure for reliable solder adhesion. The reducing tee shape allows a direct transition without separate reducer couplings. Joint integrity depends on proper cleaning flux and solder technique.

Pressure and Temperature Performance in Service

The copper body handles typical domestic hot and cold water pressures and temperatures without degradation. Copper resists internal corrosion and scale buildup in potable systems. Thermal expansion matches the connected copper tube to maintain joint seal integrity during temperature cycles. No moving parts or seals exist to wear or leak over time.
