Adapter Dimensions and Threads
The Legend Valve 450-790 is a copper reducing adapter that connects a 1-1/4 inch sweat inlet to a 3/4 inch male NPT outlet. It suits plumbers and DIY installers joining different pipe sizes in water-supply lines.
Flow Capacity and Pressure Limits
The 1-1/4 inch to 3/4 inch reduction handles typical residential flow rates while the copper body withstands standard plumbing pressures. The step-down restricts volume compared to a full-bore fitting, so high-demand fixtures may see reduced pressure.
California Proposition 65 Notice
This product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. Installers should follow safe-handling practices and local codes when working with the adapter.

Questions about this item
Will this 1-1/4" x 3/4" copper reducing MNPT adapter connect to my existing copper pipe and male threaded fitting?
Yes, the adapter is a reducing C x MNPT type with 1-1/4" x 3/4" inside diameter and 1-3/8" x 3/4" outside diameter, made to join copper pipe to a male threaded connection.
How can I verify the adapter is seated correctly after soldering to the copper pipe and threading the male end?
Inspect the soldered cup joint for a full, even fillet around the circumference and pressure-test the assembly; no leaks at the sweat or threaded joint confirm it is working as intended.
Does the box include thread sealant or tape for the male NPT end, or must I buy those separately?
The package contains only the copper reducing adapter; pipe-thread sealant or Teflon tape for the male NPT connection must be purchased separately.
