Product identity

Legend Valve 450-734 is a 1" x 3/4" copper reducing adapter with a female NPT thread. It connects a larger copper pipe to a smaller threaded fitting in plumbing systems. The transparent finish shows the copper construction. This new component suits installers who need a reliable transition between different pipe diameters.

Suitable installers

Plumbers joining 1 inch copper tube to a 3/4 inch female threaded port will find this adapter fits the task. The reducing C x FNPT design handles the specific diameter change without extra fittings. Buyers who need a straight coupling, a different thread type, or a larger size range should look at other fittings.

Critical specification

The 1" x 3/4" (ID) and 1-1/8" x 3/4" (OD) dimensions determine whether this adapter matches the pipe and port you are joining. Verify both inner and outer diameters against your existing copper tube and threaded fitting before purchase. California Proposition 65 warnings apply to this product.

Questions about this item

Will the 1" x 3/4" copper adapter fit the existing copper pipe and female-threaded valve I am keeping?

The adapter reduces a 1" copper tube to a 3/4" female NPT thread, so it connects directly to your existing copper line and threaded valve without extra fittings.

How can I confirm the joint is watertight once the adapter is soldered and threaded in place?

Pressurise the system and inspect the soldered cup and threaded connection for leaks; a dry joint and no drips under pressure show it is working as intended.

Does the package include thread sealant or solder, or must I buy them separately?

The box contains only the copper reducing adapter; flux, solder and thread sealant are not included and must be purchased separately.
