Copper Reducing Coupling 2-1/2" x 1-1/2
This copper reducing coupling joins a 2-1/2 inch pipe to a 1-1/2 inch pipe using sweat connections on both ends. It is designed for plumbing professionals and DIY installers working on residential or light commercial water supply lines. The fitting meets standard copper tube sizing for reliable solder joints.
Replaces mismatched pipe diameters
Use this coupling when transitioning between two different copper pipe sizes without threading or compression fittings. The jump is worth it when a clean, permanent soldered joint is preferred over mechanical adapters. It eliminates the need for multiple bushings or improvised reducers in a single connection.
Fits standard copper tubing systems
The coupling slides over the outside diameter of Type K, L or M copper tube and is secured by soldering. No special tools beyond a torch and flux are required. It frees up space compared to threaded reducer assemblies and maintains full flow capacity through the reduced section.

Questions about this item
What pipe diameters does the 2-1/2" x 1-1/2" copper reducing coupling connect?
It joins a 2-1/2 inch inside-diameter copper tube to a 1-1/2 inch inside-diameter copper tube, with outside diameters of 2-5/8 inch and 1-5/8 inch respectively.
How is this C x C coupling installed and what common step is missed?
Clean both tube ends, apply flux, slide the coupling on, then heat the joint evenly with a torch until solder flows completely around each socket; the step often missed is heating both sockets long enough for full capillary action.
When should the coupling be inspected or replaced after installation?
Inspect for green corrosion or leaks after the system is pressurised and again during routine plumbing checks; replace if any pitting, cracking or persistent seepage appears at the solder joints.
