Copper Reducing Tee for Large-Diameter Systems

The Legend Valve 450-336 is a copper reducing tee built for plumbing installations that join two 4-inch lines to a 1-1/2-inch branch. It serves contractors and maintenance crews who need a reliable C x C x C sweat fitting for water distribution or hydronic loops.

Step Up from Smaller Branch Tees

Standard tees with equal outlets cannot reduce flow to a smaller service line without extra couplings. This single-piece fitting eliminates those joints, cutting potential leak paths and solder time when the design calls for a 1-1/2-inch take-off from a 4-inch main.

Handles High-Volume Mains with a Reduced Outlet

The 4-inch by 4-inch run accommodates high-capacity supply lines while the 1-1/2-inch branch feeds smaller zones or equipment. It is not suited for systems that require a larger branch size or a different connection method such as threaded or press-fit ends.

Questions about this item

What pipe diameters does the 4 x 4 x 1-1/2 reducing tee connect?

The tee joins two 4-inch copper pipes on the run and one 1-1/2-inch copper pipe on the branch, all with sweat (C x C x C) sockets.

Which soldering step is most often missed when installing this copper tee?

Clean every socket and pipe end with emery cloth, apply flux to both surfaces, then heat the fitting evenly until solder flows completely around each joint.

When should this copper reducing tee be inspected or replaced?

Inspect joints for green corrosion or drips during routine plumbing checks; replace the tee if pinhole leaks develop or if the system is re-piped.
