What this fitting does

The Legend Valve 310-507NL is a no-lead hex bushing that reduces a 4-inch male NPT connection to a 3-inch female NPT connection. It is cast from bronze and intended for potable-water plumbing where lead-free components are required.

The size reduction you must match

This single bushing steps down exactly from a 4-inch MNPT thread to a 3-inch FNPT thread; any other pipe or fitting diameter will not seal correctly. Verify both thread sizes before ordering because no adapter is included.

Proposition 65 notice included

The manufacturer ships the part with California Proposition 65 warnings stating the product contains chemicals known to cause cancer and birth defects or other reproductive harm. No additional accessories, sealants or software are bundled with the fitting.

Questions about this item

How does the 4 inch by 3 inch sizing work when I install this bushing in a pipe run?

The bushing reduces a 4 inch male pipe thread down to a 3 inch female pipe thread so you can join two different pipe sizes directly.

What thread standard do the MNPT and FNPT connections follow?

Both ends use National Pipe Taper threads that seal by thread interference when tightened with sealant or tape.

What tool fits the external hex on this no-lead bronze bushing?

The external hex flats accept a standard pipe wrench or adjustable spanner for installation.
