SKU CH-CV7Z-CJ7JF

Connects three copper tubes at different diameters, rated for 582 psi at 100 °F and temperatures from -20 °F to 400 °F

  • Reduces pipe diameter from 3/4 to 1/2 in for flexible plumbing layouts
  • Wrot copper construction resists corrosion and handles 582 psi at 100°F
  • Operates reliably from -20°F to 400°F across heating and cooling systems
  • ASME/ANSI B16.22 compliant for code-approved installations
  • Sweat-style C x C x C connections create permanent, leak-free joints

Copper Reducing Tee 3/4 x 1/2 x 1/2 in

This Nibco 611 reducing tee is a wrot copper fitting with C x C x C connections for joining 3/4 inch and 1/2 inch tubes. It is built to ASME/ANSI B 16.22 standards and rated for a maximum pressure of 582 psi at 100 degrees F. The temperature range spans -20 to 400 degrees F, making it suitable for hot and cold water systems.

Suitable for copper tube reductions.

Plumbers reducing a 3/4 inch line to two 1/2 inch branches will find the correct socket sizes here. Installers needing a straight coupling, a different reduction ratio, or a fitting for iron pipe should select another product. The sweat connection style also means it is not compatible with press or push-fit systems without adapters.

582 psi pressure rating at 100 degrees F

This single figure defines the safe working limit for the fitting in typical residential and light commercial service. Systems operating above this pressure or beyond the 400 degree F upper temperature bound require a higher-rated component. Always verify that design conditions stay within the published range before installation.

Questions about this item

What copper tubing sizes must I have on hand to connect this 3/4 x 1/2 x 1/2 in reducing tee?

You need 3/4 in tubing for the run and 1/2 in tubing for both outlets; the fitting is designed for C x C x C solder joints on those exact diameters.

Will this tee handle the pressure and temperature of my existing 582 psi @ 100 °F copper system?

Yes, it is rated for 582 psi at 100 °F and a temperature range of -20 to 400 °F, matching typical residential copper installations.

How can I verify the joint is sound after soldering this Nibco 611 tee?

Pressurise the line to its working pressure and inspect each soldered cup for leaks; a dry, bubble-free joint confirms the fitting meets ASME B16.22 requirements.
