Bronze Straight Union Trap

The Nibco 7333LF-114 is a bronze straight union trap designed for potable water systems. It connects a 1 1/4 inch copper tube on one side to a 1 1/4 inch FNPT thread on the other. The fitting meets ASME B16.18, NSF/ANSI 61, and NSF/ANSI 372 standards. It is rated for a maximum operating pressure of 351 psi at 200 degrees F.

Suits copper potable water lines

This union suits installers joining copper tubing to threaded pipe in potable water applications. The lead-free bronze construction complies with NSF/ANSI 372 requirements. It is not intended for gas, oil, or high-temperature steam service. Builders needing a different tube size or connection type should select an alternative fitting.

Simple sweat and thread assembly

Installation requires sweating the cup end to the copper tube and threading the FNPT end to the mating pipe. Use compatible flux and solder for the sweat joint and appropriate thread sealant on the FNPT side. Overheating during soldering can damage the bronze body or seat. Ensure the pipe is properly deburred and cleaned to prevent leaks at the joint.

Questions about this item

What pipe size and thread type must the existing plumbing have to connect to the 1 1/4 in FNPT end?

The fitting's Side B requires a 1 1/4 in male NPT thread to mate with its female NPT connection.

Can the 1 1/4 in copper tube side join older copper piping of the same nominal size?

Yes, the cup end accepts 1 1/4 in copper tube with a 1 3/8 in outer diameter for a standard sweat joint.

How can I verify the joint is sound at the rated 351 psi and 200 Degrees F limits?

Pressurise the system to its working pressure and inspect the sweat and threaded joints for leaks while at operating temperature.
