1/2" Drop Adapter Trap

The Nibco 7035LF-12 is a cast DZR brass drop adapter trap designed for potable water systems. It connects a 1/2 inch copper sweat fitting on one side to a 1/2 inch FNPT threaded connection on the other. The fitting meets ASME B16.18, NSF/ANSI 61, and NSF/ANSI 372 standards for safe drinking water applications.

Sustained Pressure and Temperature Performance

This adapter is rated for a maximum operating pressure of 577 psi and a maximum operating temperature of 200 degrees F. The bronze construction using material grade C87850 maintains structural integrity under continuous high-pressure conditions without deformation. Compliance with ISO 9001 manufacturing standards ensures consistent material quality across production batches.

Installation Compatibility Checks

Verify that your existing piping uses 1/2 inch copper tube with a 5/8 inch outer diameter for the sweat connection side. Confirm the mating component has a 1/2 inch FNPT thread profile for the adapter side. Ensure the system operating parameters do not exceed the stated pressure and temperature limits for this fitting.

Questions about this item

How much heat can the 1/2" C x FNPT drop adapter handle during continuous hot-water circulation?

The bronze body is rated for a maximum operating temperature of 200 degrees F, so it will not degrade under normal domestic hot-water loop conditions.

What pipe and tube sizes must already be in place for this 7035LF-12 adapter to connect without extra reducers?

You need a 1/2 in copper tube with a 5/8 in outer diameter on the sweat side and a 1/2 in FNPT threaded port on the mating fitting.

Will this C87850 bronze adapter meet the same lead-free and potable-water standards as older brass traps still in the system?

Yes, it complies with NSF/ANSI 372 and NSF/ANSI 61 for lead-free potable water use, matching current code requirements for the existing installation.
