Copper Reducing Tee for Plumbing Systems

The Nibco 611RR is a wrot copper reducing tee designed for residential and commercial plumbing installations. It connects three copper tubes in a C x C x C sweat configuration with a 1 in x 1/2 in x 1 in nominal tube size. The fitting meets ASME/ANSI B16.22 standards for pressure fittings.

Upgrading From Repairs or Mismatched Fittings

This tee replaces worn couplings, damaged tees or improvised reducer combinations when a branch line drops from a 1 inch main to a 1/2 inch fixture supply. The jump is worth it when a single factory-made fitting eliminates multiple joints, reducing potential leak paths and installation time on copper potable water or hydronic heating systems.

Pressure and Temperature Limits of the Standard

The ASME/ANSI B16.22 standard governs the pressure rating of 494 psi at 100 degrees Fahrenheit for this fitting size. The wrot copper construction handles a continuous operating range from -20 degrees to 400 degrees Fahrenheit. Installers must ensure system pressure and temperature stay within these limits and that solder joints are made with lead-free alloys approved for the application.

Questions about this item

What copper tube sizes does the 1 x 1/2 x 1 in reducing tee accept?

The tee fits nominal 1 in, 1/2 in, and 1 in copper tubes with outside diameters of 1-1/8 in, 5/8 in, and 1-1/8 in respectively.

How is the C x C x C connection made and what step is often missed?

Each end is soldered to the tube; the joint must be cleaned, fluxed, heated evenly, and filled with solder — skipping thorough cleaning causes leaks.

When should the reducing tee be inspected or replaced?

Inspect joints periodically for corrosion or leaks; the fitting is rated to 494 psi at 100 Degrees F and a temperature range of -20 Degrees to 400 Degrees F per ASME/ANSI B 16.22.
