3 inch No Lead Hex Bushing

Plumbers reducing large diameter pipe

This bushing suits installers joining 3 inch and 1-1/2 inch NPT threaded components in water supply systems. It is not intended for applications requiring a different thread standard, a smaller or larger reduction step, or a fitting rated for gas service unless separately approved.

3 inch MNPT to 1-1/2 inch FNPT reduction

The defining specification is the thread size transition from 3 inch male NPT to 1-1/2 inch female NPT. Verify that both mating parts match these exact thread dimensions and standards before installation.

Questions about this item

Will the 3 inch male NPT threads on this Legend Valve 310-504NL bushing mate cleanly with my existing 1-1/2 inch female NPT pipe?

Yes, the bushing is threaded 3 inch MNPT on one end and 1-1/2 inch FNPT on the other so it connects directly between those two pipe sizes.

How can I verify the no-lead cast bronze body is seated correctly after installation?

Tighten the hex flats with a wrench until the joint feels firm and then pressure-test the line; a leak-free seal confirms proper seating.

Does the box include thread sealant or tape for the NPT connections?

The package contains only the hex bushing; pipe thread sealant or Teflon tape must be purchased separately.
