Copper 90-degree elbow for 4-inch tube

The Nibco 607 is a wrot copper fitting designed to join two 4-inch tubes at a right angle. It suits residential and commercial drainage installations that require a smooth 90-degree change of direction. The C x C connection accepts standard copper tube on both ends for soldered joints.

Replaces worn or mismatched copper bends

Use this elbow when an existing 90-degree fitting leaks, corrodes or no longer matches the pipe layout after a remodel. The jump is worth it when the system operates up to 293 psi at 100 degrees F and stays within the -20 to 400 degrees F range. It meets ASME/ANSI B 16.22 for dimensional consistency.

Slip both ends onto cleaned tube

Installation is straightforward for anyone familiar with copper soldering: clean, flux, fit and heat. What usually goes wrong is insufficient cleaning or uneven heating, which leaves voids in the solder and causes drips under pressure. Allow the joint to cool naturally before testing.

Questions about this item

What outside diameter must the copper tube have to fit the 4 in C x C elbow?

The fitting accepts tube with a 4-1/8 in outside diameter for a sweat joint on each end.

Which step is often missed when sweating the 90 degree elbow onto the tube?

Clean both the tube end and the fitting socket with emery cloth, apply flux, then heat the joint evenly until the solder flows into the cup.

What temperature and pressure limits should be checked when the system is inspected later?

The elbow is rated for 293 psi at 100 °F and a continuous range of –20 °F to 400 °F per ASME B16.22.
