  • TypeDrain Components
  • MaterialHAWA
  • Reduces pipe diameter from 1-1/4 to 1 inch for tight transitions
  • Wrot copper construction resists corrosion across -20 to 400 degree range
  • Rated 439 psi at 100 degrees for reliable high-pressure service
  • Meets ASME B16.22 standard ensuring code-compliant installations
  • 90-degree close-rough design simplifies routing in confined spaces

Reducing Elbow for Copper Piping

The Nibco 607R is a wrot copper 90-degree reducing elbow designed for C x C tube fitting connections. It joins a 1-1/4 inch nominal tube to a 1 inch nominal tube in drain, waste, and vent systems. The close rough design suits tight routing where a standard radius elbow will not fit.

Replaces Standard Radius Fittings

Use this elbow when space constraints prevent the installation of a long-radius fitting or when transitioning directly between the two listed tube sizes. The jump is worth it only if the system operates within the 439 psi pressure rating at 100 degrees F and the temperature range of -20 to 400 degrees F. It does not suit applications requiring a larger reduction step or a different fitting angle.

Solder Installation and Clearance Checks

Installation requires standard copper soldering tools and flux for the C x C connections. Ensure the 1-3/8 inch and 1-1/8 inch outside diameters clear surrounding structure before assembly. The most common issue is insufficient pipe insertion depth or overheating the joint, which can weaken the fitting or cause leaks under pressure. Verify compliance with ASME/ANSI B16.22 for the intended service.

Questions about this item

What copper tube sizes does the 1-1/4" x 1" reducing elbow connect?

It joins 1-1/4 inch and 1 inch copper tube, with outside diameters of 1-3/8 inch and 1-1/8 inch respectively.

How is the C x C close rough elbow installed, and what step is often missed?

Clean both tube ends, apply flux, insert fully into each cup, then solder the joint; the step often missed is ensuring full insertion before heating.

What pressure and temperature limits should I plan for over the fitting's service life?

Rated for 439 psi at 100 degrees F and a temperature range of -20 to 400 degrees F per ASME/ANSI B16.22.
