Legend Valve 450-448 4 x 2-1/2 Red Coupling Ftg x C

4 x 2-1/2 Reducing Copper Coupling

This copper reducing coupling connects a 4-inch fitting end to a 2-1/2-inch copper pipe end for plumbing installations. The transparent finish shows the bare metal surface for visual inspection of joint quality. It is suited for residential or commercial water supply systems requiring a step-down transition.

Fitting-by-copper design for solder joints

The Ftg x C configuration means one end slides into a fitting hub while the other accepts a copper tube directly, so only one solder joint is needed per connection. Copper construction resists corrosion and handles typical hot and cold water temperatures. The reducing shape saves space compared with separate reducer and coupling combinations.

Verify tube and fitting diameters before ordering

Confirm that your existing system uses 4-inch and 2-1/2-inch nominal copper sizes matching the fitting and tube ends respectively. Ensure local codes permit copper reducing couplings for the intended application and that you have appropriate flux and lead-free solder.
