Copper Reducing Adapter for Plumbing Systems
The Legend Valve 450-794 connects a 1-1/2 inch copper pipe to a 1-1/4 inch male NPT thread. It serves installers who need a reliable transition between different pipe diameters in residential or commercial water lines.
Lead-Free Copper Construction Meets Safety Standards
The adapter is made from copper and carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm. No thermal, noise or power specifications apply to this passive fitting.
Simple Installation With No Extra Components
The package contains only the adapter itself. No additional software, seals or tools are bundled, so the installer must supply compatible flux, solder and pipe preparation materials.

Questions about this item
How do I install the Legend Valve 450-794 copper reducing MNPT adapter, and what step is commonly missed?
Clean both the 1-1/2" copper tube end and the 1-1/4" male NPT threads thoroughly, apply flux to the tube and thread sealant to the NPT side, then solder the cup joint while the fitting is cool enough to avoid burning the sealant.
What maintenance or replacement will the Legend Valve 450-794 adapter need over time?
Inspect the soldered cup joint and the threaded connection annually for green corrosion or mineral buildup; replace the adapter if the copper shows pitting, the threads strip, or a leak appears at either joint.
What is the first limit that appears on the Legend Valve 450-794 adapter under sustained hot-water use?
The copper body handles typical residential hot-water temperatures, but the thread sealant on the 1-1/4" MNPT side may degrade first if the system regularly exceeds the sealant's rated temperature.
