Copper reducing tee fitting with three sweat connections in T shape

Nibco, Inc.

Nibco, Inc. C611 reducing tee trap

SKU CH-KH21-TSHMM MPN C611

Reducing tee joins 1 x 3/4 x 1 inch copper lines with sweat connections rated to 494 psi at 100 degrees F and service from -20 to 400 degrees F per ASME B16.22

  • TypeDrain Components
  • Reducing tee joins 1 in., 3/4 in., and 1 in. copper lines
  • Wrought copper construction resists corrosion across -20 °F to 400 °F range
  • Rated 494 psi at 100 °F for reliable high-pressure service
  • C x C x C sweat connections simplify installation on copper tubing
  • Meets ASME/ANSI B16.22 standard for quality assurance

Copper Reducing Tee 1 x 3/4 x 1

This copper reducing tee connects three tube ends in a C x C x C configuration with 1 in., 3/4 in., and 1 in. tube sizes. It is designed for plumbing systems that require a branch line from a main run. The wrought copper construction suits residential and commercial water supply installations.

Direct solder-joint replacement

The fitting replaces threaded or compression tees where a permanent, leak-free solder joint is preferred. It is worth the switch when the system operates up to 494 psi at 100 °F and the installer can make clean copper-to-copper connections. No adapter is needed because all three ports share the same C x C x C connection type.

Sustained pressure and temperature performance

The tee withstands continuous pressures up to 494 psi at 100 °F and remains rated across a temperature range of -20 °F to 400 °F. ASME/ANSI B16.22 compliance confirms the fitting meets dimensional and material requirements for long-term service. Performance holds steady under prolonged thermal cycling without degradation.

Questions about this item

What copper tube sizes does the C611 reducing tee connect?

The C611 connects 1 inch, 3/4 inch, and 1 inch copper tubes with C x C x C solder joints and outside diameters of 1-1/8 in., 7/8 in., and 1-1/8 in.

How is the wrot copper tee installed, and what step is often missed?

Clean each tube end and fitting socket, apply flux, assemble the three joints, then solder all connections evenly; the step often missed is heating each joint uniformly so solder flows completely around the cup.

When should the reducing tee be inspected or replaced?

Inspect for leaks, corrosion, or joint fatigue during system checks; replace if pressure exceeds 494 psi at 100 °F or if operating temperatures fall outside the -20 °F to 400 °F range.
