1" FTG x MNPT Copper Adapter

This NIBCO 6042 adapter connects a 1-inch tube fitting to a 1-inch male NPT thread. It is made from wrot copper alloy C12200 for potable-water and medical-gas systems. The fitting meets ASTM B75, ASME B16.22 and MSS SP-104 standards. It carries NSF/ANSI 61 Annex G certification for lead-free compliance.

Pressure & Temperature Headroom

Rated for 395 psi at 200 °F, the adapter handles typical residential and commercial pressures with margin. The service range extends from -20 °F to 400 °F, covering chilled-water lines and high-temperature hydronic loops. Installers needing higher pressure ratings or cryogenic service below -20 °F must select a different class of fitting.

Build Integration

The 1-1/8-inch outside diameter slips into standard 1-inch copper tube before soldering, while the MNPT end threads into valves, pumps or equipment. No flare tools or press jaws are required beyond a torch and flux. The NSF/ANSI 61 and NFPA 99 listings allow direct use in healthcare gas and vacuum piping without additional approvals.

Questions about this item

Will the 1 in FTG end connect to the 1 in copper pipe I already have installed?

Yes, the 1 in FTG end is made to fit 1 in nominal copper tube. The wrot copper body meets ASTM B75 Alloy C12200 and ASME B16.22 dimensions for standard copper piping.

How can I verify the joint is sound after soldering the adapter in place?

Pressurise the system up to the 395 psi rating at 200 °F and check for leaks. The adapter is third-party certified to NSF/ANSI 61 Annex G and MSS SP-104 for potable water and medical gas service.

Does the package include any flux, solder or thread sealant for the MNPT connection?

The box contains only the copper adapter. Flux, lead-free solder and pipe-thread sealant must be purchased separately to complete the installation.
