Copper Reducer for Drain Systems

The Nibco 600R is a wrot copper reducer designed for drain components in plumbing installations. It connects a 3-inch tube to a 2-1/2-inch tube using a C x C fitting connection type. The fitting has an outside diameter of 3-1/8 inches by 2-5/8 inches and meets ASME/ANSI B 16.22 standards for material and dimensions.

Soldered Installation with Standard Tools

Installation requires soldering the copper-to-copper joints using appropriate flux and lead-free solder for potable water or drainage systems. The main risk is overheating the fitting, which can damage the material or create weak joints that leak under pressure. Proper tube preparation, cleaning, and flux application are essential to avoid voids or incomplete seals during the sweating process.

Suits Plumbers Reducing Drain Line Diameter

This reducer suits professional plumbers and maintenance crews transitioning between nominal 3-inch and 2-1/2-inch copper drain lines in commercial or residential systems rated up to 317 psi at 100 degrees Fahrenheit. It is not intended for press-fit or push-to-connect installations, nor for systems requiring threaded or flanged connections. Builders needing alternative joining methods or different material compatibility should evaluate other fitting types.

Questions about this item

How can I verify the reducer is leak-free after soldering?

Pressurise the line up to 317 psi at 100 °F and inspect the C x C joints for any moisture; the fitting is rated to hold that pressure across its full temperature range.

What comes in the package and what must I source separately?

The box contains only the wrot-copper reducer; you will need solder, flux, emery cloth and any required hangers or straps to complete the installation.

Which size should I select for a 3 in to 2-1/2 in nominal copper line?

Choose the 600R model with 3 in x 2-1/2 in tube size and 3-1/8 in x 2-5/8 in outside diameter; it meets ASME/ANSI B 16.22 for that exact transition.
