Bathware Adapter for Copper Pipe Connections

This Legend Valve 450-792 adapter joins a 1-1/4" copper pipe to a 1-1/2" male NPT thread. It is intended for plumbing installations where a reducing copper-to-threaded transition is required. The fitting is new and supplied in a transparent finish.

Check Pipe Diameter and Thread Standard Before

Verify that your existing copper line measures 1-1/4" ID and that the mating component uses a 1-1/2" male NPT thread. Confirm the application permits a reducing C x MNPT configuration and that local codes accept this fitting type. The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Thermal and Noise Behaviour in Normal Use

As a passive brass fitting, the adapter generates no heat, noise or power draw during operation. It simply conveys water between the soldered copper end and the threaded connection. No active cooling or electrical supply is involved, so thermal and acoustic performance are not applicable.

Questions about this item

What is included with the Legend Valve 450-792 adapter and is any extra sealant required?

The box contains the copper reducing male NPT adapter only; thread sealant or tape must be purchased separately for installation.

Which size variant of the 450-792 should I choose for a 1-1/4 inch copper pipe connecting to a 1-1/2 inch male thread?

Select the single listed size 1-1/4" x 1-1/2" C x M; it matches a 1-1/4 inch copper tube to a 1-1/2 inch male NPT fitting.

How does the 1-1/4" x 1-1/2" C x M sizing translate when the adapter is soldered into a working plumbing system?

The sweat end accepts 1-1/4 inch copper tube (1-3/8 inch OD) and the threaded end provides a 1-1/2 inch male NPT connection for the mating fitting.
