Product Identity

The Legend Valve 450-756 adapter connects a 1-1/4 inch copper pipe to a male NPT thread. It suits plumbers and DIYers joining dissimilar fitting types in water supply lines.

Interface Constraints

The copper-to-thread transition handles pressure and temperature within standard plumbing limits. California Proposition 65 warnings apply because the material contains listed chemicals. The transparent finish allows visual inspection of the joint.

Upgrade Context

This fitting replaces a direct solder joint when a threaded connection is needed for maintenance or appliance hookup. It is not suited for systems requiring a larger bore or a different thread standard.

Questions about this item

Which size should I choose for a 1-1/4 inch copper pipe?

The adapter fits 1-1/4 inch inside diameter copper and provides a 1-3/8 inch outside diameter male NPT thread.

What does the 1-3/8 inch OD mean when installed?

It is the outside diameter of the male NPT end that threads into a matching female fitting.

How does the C x MNPT connection limit the joint?

The copper sweat end requires soldering to pipe, while the MNPT end seals with thread tape or compound.
