Copper Adapter for 3/4 Inch Tube

This Nibco 604 adapter connects a 3/4 inch copper tube to a male NPT thread. It is made from wrought copper for mechanical plumbing systems. The fitting suits installers who need a reliable transition between tube and threaded pipe. It arrives new and ready for installation.

Suits copper tube installations needing male

Plumbers joining copper tube to threaded fittings will find this adapter appropriate. It is not for systems that require a female thread, a different tube diameter, or a press-fit connection. Buyers working with plastic, steel or larger copper sizes should select a different fitting.

Fits into copper plumbing assemblies

The adapter slides onto 3/4 inch copper tube for a soldered joint on one end while the other end provides a male NPT thread. It frees the installer from needing a separate coupling and thread adapter. The wrought copper construction integrates with standard copper pipe workflows.

Questions about this item

What copper tubing size must I have on hand to connect the 604 adapter?

The 604 adapter is made for 3/4-inch copper tube, so you need that exact tubing size and a compatible soldering setup to join it.

Will the 604 adapter thread directly into my existing iron or brass fittings?

Yes, the male NPT threads on the 604 adapter are designed to screw into standard female NPT ports on iron, brass or other threaded fittings you already have.

How can I confirm the 604 adapter is sealed properly after soldering and threading?

Pressurise the line and inspect every joint; a dry, leak-free connection at both the soldered copper end and the threaded NPT end shows the 604 is working as intended.
