Legend Valve 3" x 1-1/4" No Lead Hex Bushing

This Legend Valve hex bushing reduces a 3-inch male NPT thread to a 1-1/4-inch female NPT thread. It is cast from no-lead bronze for potable water compliance. The component suits plumbing professionals and maintenance crews joining dissimilar pipe sizes in commercial or residential systems.

Suits installers needing lead-free bronze reduction

This fitting serves installers who require a no-lead bronze bushing for threaded NPT connections. It does not suit buyers who need a different thread standard, a non-reducing coupling, or a material other than cast bronze for chemical compatibility.

3" MNPT to 1-1/4" FNPT threaded reduction

The single specification that decides fit is the 3-inch male to 1-1/4-inch female NPT thread pairing. Verify that both mating components use matching NPT threads and that the no-lead bronze alloy meets the system pressure and fluid requirements.

Questions about this item

What thread sizes must match for the 3" x 1-1/4" hex bushing to seal correctly?

The bushing has a 3" male NPT end and a 1-1/4" female NPT end; both threads must engage cleanly with matching NPT fittings to prevent leaks.

Which wrench flats should be used when tightening the hex bushing into a joint?

Apply a wrench only to the cast bronze hex body — never to the pipe or fitting — and turn until the joint feels snug plus one-half turn to seat the taper without cracking the threads.

When should the no-lead bronze bushing be inspected or replaced in a potable water line?

Check for green patina, seepage or restricted flow during annual system checks; replace the bushing if corrosion appears or after any freeze event that stresses the joint.
