SKU CH-Y4NW-PAKS2

A wrot copper reducing elbow joins 3/4 in and 1/2 in tubes at 90 degrees with a 582 psi rating at 100 degrees F

  • Reduces pipe size while changing direction 90°
  • Wrot copper construction handles 582 psi at 100°F
  • Operates from -20°F to 400°F continuous service
  • C x C sweat connection fits 3/4 in and 1/2 in tube
  • Meets ASME/ANSI B 16.22 dimensional standards

Product Identity

The Nibco 607R is a wrot copper reducing elbow designed for plumbing systems that need a 90-degree directional change between 3/4-inch and 1/2-inch copper tubing. It serves installers who require a permanent, soldered C x C joint in residential or commercial water lines.

Sustained Pressure Behaviour

The fitting carries a maximum pressure rating of 582 psi at 100 degrees Fahrenheit and operates across a temperature range from -20 to 400 degrees Fahrenheit. These limits define its safe envelope for continuous hot-water circulation or high-pressure supply rather than brief test spikes.

Standard Constraint

It conforms to ASME/ANSI B 16.22, which governs dimensions and tolerances for wrot copper pressure fittings. The standard fixes the outside diameters at 7/8 inch and 5/8 inch, so the elbow cannot be used with tubing or press systems that fall outside those dimensions.

Questions about this item

How much heat can the copper elbow handle in continuous service?

The fitting is rated from -20 °F up to 400 °F, so it will withstand typical hot-water and heating-system temperatures all day.

What pipe sizes and tools are needed to install this 3/4 in x 1/2 in C x C elbow?

You need 7/8 in OD copper tube on one side, 5/8 in OD on the other, plus a torch, flux and lead-free solder for sweat connections.

Will the 582 psi pressure rating hold on an older 1/2 in copper branch line?

Yes, the ASME B16.22 rating of 582 psi at 100 °F applies to the reducing elbow itself, matching standard copper tube pressures.
