  • Meets ASME/ANSI B16.22 standard for quality assurance
  • Sweat connections on all three ends ensure leak-free joints

Copper Reducing Tee 1-1/2" x 1" x 1-1/2

The NIBCO 611RR is a wrot copper fitting with C x C x C connections. It joins tubes of 1-1/2 in, 1 in and 1-1/2 in nominal size. The fitting is rated for 408 psi at 100 degrees F. It suits plumbing and heating installations that require a branch reduction.

Installers needing a sweat copper tee

This component fits copper tubing systems built to ASME/ANSI B 16.22. It handles temperatures from -20 to 400 degrees F. It does not suit systems using threaded, press or push-fit connections. Builders who need a straight coupling or a different outlet arrangement should select another fitting.

Pressure rating 408 psi at 100 degrees F

The maximum working pressure is 408 psi at 100 degrees F. This single figure determines whether the tee meets the design pressure of the system. Verify the system pressure before installation.

Questions about this item

How is the 1-1/2" x 1" x 1-1/2" copper reducing tee installed and what step is often missed?

Clean each tube end and the fitting sockets, apply flux, insert tubes fully into the C x C x C connections, then solder all three joints evenly; the step often missed is heating each joint uniformly so solder flows completely around the socket.

What maintenance or replacement will the reducing tee need later?

The wrot copper body resists corrosion, so no routine maintenance is required; replacement only becomes necessary if a joint leaks after thermal cycling or if system pressure exceeds the 408 psi rating at 100 Degrees F.

What limit appears first under sustained high-temperature use?

The temperature ceiling of 400 Degrees F is reached before the 408 psi pressure rating becomes a factor, so prolonged exposure above 400 Degrees F will degrade the fitting first.
