90-Degree Drop Ear Elbow

The Nibco 70735RLF-3412 is a sweat fitting elbow designed for potable water systems. It connects a 3/4 inch copper tube on one side to a 1/2 inch FNPT thread on the other. The fitting is made from low-lead cast bronze grade C87850. It meets ASME B 16.18, NSF/ANSI 61 and NSF/ANSI 372 standards.

Replaces Standard Copper Elbows

This drop ear elbow replaces a standard copper elbow when a secure mounting point is required. The integrated ear allows the fitting to be fastened to a stud or blocking. The jump is worth it when installing supply lines for fixtures such as shower arms or tub spouts where movement must be prevented.

Sustained Pressure And Temperature

The bronze construction handles a maximum operating pressure of 466 psi and a maximum operating temperature of 200 degrees F. These ratings support continuous hot and cold water service without degradation. The material resists dezincification and meets low-lead requirements for safe drinking water delivery.

Questions about this item

What size copper tube does the 70735RLF-3412 elbow accept on the sweat side?

The sweat connection is sized for 3/4 in copper tube with a 7/8 in outer diameter.

How is the drop-ear elbow secured during installation, and what step is often missed?

The drop ears provide mounting holes for screws or nails; the step often missed is fastening the ears to framing before soldering the copper joint.

When should the bronze elbow be inspected or replaced in a potable-water system?

Inspect for leaks or corrosion at each system check; replace if the joint shows green patina, pitting, or any seepage at the threaded or sweat connections.
