Bronze Elbow for Potable Water

This Nibco 7073-LF elbow joins 1 1/2 inch copper tube to a 1 1/2 inch FNPT thread using a 90 degree sweat connection. The C87850 bronze body meets ASME B16.18, NSF/ANSI 61 and NSF/ANSI 372 for potable water service. Rated to 327 psi and 200 degrees F, it is suited for residential and light commercial plumbing.

Replaces Threaded or Flanged Elbows

The cup-by-FNPT design removes the need for a separate male adapter when transitioning from copper to threaded pipe. The jump is worth it when a single fitting reduces leak paths and installation time on supply lines, risers or fixture branches. ISO 9001 manufacture supports consistent dimensional quality.

Suits Installers Using 1 1/2 Inch Copper

Plumbers running 1 1/2 inch copper who need a female threaded outlet at a right angle will find this fitting matches the tube OD and pressure class. It is not for systems requiring press, push-fit or compression ends, nor for applications outside the listed pressure and temperature ratings. Builders needing a different connection type should select an alternative configuration.

Questions about this item

What copper tube outer diameter does the 1 1/2 in cup end of the Nibco 7073-LF accept?

The cup end fits a copper tube with a 1 5/8 in outer diameter, matching the 1 1/2 in copper tube size specified for sweat soldering.

How is the FNPT threaded end of this bronze elbow sealed during installation, and what common step is missed?

Apply PTFE tape or pipe dope to the male threads before tightening into the 1 1/2 in FNPT port; the step often missed is cleaning both thread surfaces first to prevent leaks.

Which standards cover the bronze alloy C87850 used in this elbow for potable water safety?

The C87850 bronze meets NSF/ANSI 61 and NSF/ANSI 372 for drinking water health effects and lead-free compliance, and the fitting conforms to ASME B16.18.
