Frequently Asked Questions

What is a NIBCO sweat fitting adapter used for?

A NIBCO sweat fitting adapter connects copper tubing to threaded pipe in plumbing and HVAC systems. The 3/8 in CTS cup end solders onto copper tube, while the 3/8 in MNPT end threads into female pipe fittings, enabling reliable transitions in potable water and hydronic heating lines.

What are the specifications of the NIBCO 604-3/8 sweat fitting adapter?

The NIBCO 604-3/8 is a wrot copper adapter with a 3/8 in CTS cup x 3/8 in MNPT connection. It features a cup x male NPT configuration, designed for sweat (solder) installation. The wrot copper construction ensures corrosion resistance and durability in plumbing applications.
