NIBCO Sweat Fitting Adapter: 3 in CTS x 3 in Pipe, Cup x FNPT, Wrot Copper (MPN 603 3)

A NIBCO sweat fitting adapter connects copper tubing to threaded pipe in plumbing and HVAC systems. The 3 in CTS cup end solders onto copper tube, while the FNPT end mates with male threaded fittings, enabling transitions in water supply, hydronic heating, and industrial piping.

The NIBCO 603 3 is a wrot copper sweat fitting adapter with a 3 in CTS cup x 3 in FNPT connection. It is designed for soldered installation on copper tube and threaded pipe connections. The wrot copper construction provides corrosion resistance and durability in potable water and HVAC applications.
