Adapter for copper pipe reduction

This Legend Valve 450-732 adapter connects 3/4 inch copper tubing to a 1 inch female NPT thread. It is designed for residential or commercial plumbing installations where a reducing transition is required. The fitting is supplied new and carries California Proposition 65 warnings for cancer and reproductive harm.

Verify tubing and thread compatibility

Confirm that the existing copper pipe has a 3/4 inch inside diameter and that the mating component provides a 1 inch female NPT connection. The adapter's outside dimensions are 7/8 inch by 1 inch, so ensure adequate clearance for tightening. Check local codes for any restrictions on materials carrying Proposition 65 listings.

Integrates into copper piping systems

The adapter joins directly to copper pipe on one end and accepts standard NPT threaded fittings on the other, allowing a straightforward reduction in line size. Its transparent finish lets installers visually inspect the joint during assembly. No additional threading tools are needed beyond those used for typical copper sweat or press connections.

Questions about this item

What fittings come with the Legend Valve 450-732 adapter and what else is needed?

The adapter is a single copper reducing FNPT fitting with 3/4" x 1" ID and 7/8" x 1" OD. Pipe, thread sealant and any additional valves are purchased separately.

Which size variant of the Legend Valve 450-732 should I select for my plumbing job?

Only the 3/4" x 1" (ID) 7/8" x 1" (OD) copper reducing C x FNPT adapter is offered under this model number. Choose it when you need to step from 3/4" copper to 1" female threads.

What does the Proposition 65 notice mean for daily use of the Legend Valve 450-732?

The product contains a chemical listed by California as a cancer and reproductive-harm risk. Normal plumbing installation with standard protective practices keeps exposure well below levels of concern.
