Product identity

The Legend Valve 350-644 is a black hex bushing built to join a 3-1/2 inch female NPT opening with a 3 inch male NPT thread. It serves plumbers and maintenance crews who need a durable, code-compliant transition in steel piping systems.

Fit and alternatives

This fitting suits installers working with the exact 3-1/2 by 3 inch NPT size change in black steel. Jobs that require a different diameter step, a stainless or brass body, or a coupling rather than a bushing will need another part.

Deciding specification

The defining detail is the 3-1/2 inch FNPT to 3 inch MNPT thread combination. Confirm that both the pipe and the mating component match these sizes and thread standards before ordering.

Questions about this item

Will the 350-644 hex bushing thread onto my existing NPT pipes without leaks?

The bushing has FNPT internal threads and MNPT external threads, matching standard NPT pipe sizes for a direct fit.

How can I verify the 350-644 bushing is seated correctly after installation?

Tighten the hex head with a wrench until the joint feels firm and no threads are visible; then pressure-test the line for leaks.

Does the 350-644 package include any sealant or gaskets, or must I buy them separately?

Only the black hex bushing is supplied; thread sealant tape or pipe dope must be purchased separately.
