Sweat Fitting Tee for Potable Water

The Nibco 712LF-1 is a cast bronze adapter tee designed for potable water systems. It connects two 1 inch copper tubes via sweat cup connections and a 1 inch FNPT threaded branch. Rated for 395 psi maximum operating pressure and 200 degrees Fahrenheit maximum temperature.

Replaces Standard Tees When Threaded Branch Is

This fitting upgrades a straight copper run by adding a female threaded outlet without extra adapters. The jump is worth it when transitioning from sweat copper to threaded pipe or equipment at a tee junction, reducing potential leak points and installation time.

Verify Copper Tube Size and Thread Compatibility

Confirm the existing copper tubing measures 1 1/8 inch outer diameter for proper sweat fit on both run ends. Ensure the mating male pipe threads match 1 inch NPT standards and that system pressure and temperature stay within the 395 psi and 200 degree limits.

Questions about this item

What copper tube size and connection types does this tee require for sweat fitting?

The tee uses 1 in copper tube size with 1 1/8 in outer diameter on both sweat cup ends and a 1 in FNPT threaded branch for the third connection.

How do I install this low-lead cast bronze tee without damaging the threads or joints?

Clean and flux the 1 1/8 in copper tube ends, sweat solder the cup connections first, then thread the 1 in FNPT branch using appropriate sealant to avoid cross-threading the bronze.

When should I inspect or replace this tee given its pressure and temperature ratings?

Inspect joints annually for leaks or corrosion, especially after sustained use near the 395 psi or 200 °F limits, and replace if any weeping or green patina appears on the bronze body.
