Copper Reducing Tee for Potable Water

The Nibco 611R is a sweat fitting tee designed for potable water systems. It connects three copper tubes using cup connections on all sides. The run measures 2-1/2 inches on both ends while the branch reduces to 3/4 inch. This wrot copper fitting suits residential and commercial plumbing installations.

Wrot Copper Construction and Cup Connections

Wrot copper provides corrosion resistance and a smooth interior for reliable flow. Each cup end accepts the corresponding tube outer diameter for soldered joints. The reducing branch allows a smaller line to tee off a larger main without additional adapters. Sweat connections create permanent, leak-resistant seals when properly soldered.

Limits of Sweat Fitting Standards

Sweat fittings require clean tube ends, flux, and adequate heat for a sound joint. The installer must verify local code acceptance for potable water use. The reducing geometry fixes the branch size at 3/4 inch, so systems needing a different branch diameter cannot use this tee. Pressure rating depends on the solder joint quality and tube wall thickness.

Questions about this item

What copper tube sizes does the 611R reducing tee join on its three cup connections?

The tee connects two 2 1/2 in copper tube ends and one 3/4 in copper tube end, all with cup-style sweat connections.

What outside diameters must the installer's copper tubes match for this tee?

The two run ports require 2 5/8 in tube OD and the branch port requires 7/8 in tube OD for proper sweat fit.

What preparation step is critical before sweating this wrot copper tee to avoid a leaky joint?

Clean both the tube ends and the fitting cups until bright, apply flux evenly, then heat the fitting body — not the tube — so solder flows by capillary action.
