Copper 90-degree drop elbow, C by FTG, 1-1/4 inch tube size

Nibco, Inc.

Nibco, Inc. 9072 1-1/4" C x FTG Copper 90 Degree Drop Elbow

SKU CH-JZ20-QZ4FE

Connects 1-1/4" copper tube to a fitting at a 90-degree drop angle for DWV systems rated to 5 psi and 400°F

  • ASTM B75 copper alloy ensures corrosion resistance
  • 90-degree drop elbow redirects flow in tight spaces
  • C x FTG connection fits copper tube and fitting hub
  • Rated for -20 to 400 °F operating temperatures
  • Meets ASME B16.29 standard for DWV systems

Copper DWV Elbow for Drain-Waste-Vent Systems

This Nibco 9072 fitting is a wrought-copper 90-degree drop elbow sized for 1-1/4 inch nominal tube with an outside diameter of 1-3/8 inch. It connects a copper tube end to a fitting end in drain, waste and vent piping. The alloy meets ASTM B75 C12200 and ASME B16.29 standards for plumbing installations.

Pressure and Temperature Behaviour Under

The elbow is rated for a maximum pressure of 5 psi, reflecting its intended gravity-flow drainage role rather than pressurised supply lines. It withstands a temperature range from -20 to 400 degrees F, so it remains stable through seasonal extremes and hot-water discharge without softening or cracking.

Replaces Worn or Undersized Copper DWV Elbows

Use this fitting when an existing copper DWV elbow leaks, corrodes or no longer matches the 1-1/4 inch tube size required by the current layout. The jump is worth it when the system demands a C x FTG connection and code-compliant wrought-copper construction for reliable gravity drainage.

Questions about this item

Does the wrot copper construction and 5 psi pressure rating handle continuous hot-water circulation without leaking?

The fitting is rated for temperatures from -20 °F to 400 °F at a maximum pressure of 5 psi, so it will hold under normal DWV hot-water circulation.

What pipe and tools do I need to sweat this C x FTG elbow into a 1-1/4" copper DWV line?

You need 1-1/4" nominal copper tube (1-3/8" OD), lead-free solder, flux, and a propane or MAPP torch to make the soldered joints.

Will this ASTM B75 C12200 elbow join cleanly to older copper DWV pipe already in the house?

Yes, the alloy and dimensions follow ASTM B75 and ASME B16.29, matching standard copper DWV tubing used for decades.
