  • Low-lead bronze suits potable water systems

Potable Water Tee Connection

The NIBCO 710-3-4-LF is a low-lead cast bronze sweat fitting tee designed for potable water systems. It connects a 3/4 inch FNPT side, a 3/4 inch MNPT side, and a 3/4 inch copper cup side with a 7/8 inch outer diameter. This adapter tee suits plumbers joining threaded and sweat connections in residential or commercial supply lines.

Sustained Pressure and Temperature Rating

The fitting carries a maximum operating pressure of 466 psi and a maximum operating temperature of 200 degrees Fahrenheit. These ratings support continuous service in hot and cold water distribution without degradation. The low-lead bronze construction maintains structural integrity under prolonged thermal cycling and pressure loads.

Bronze Build and Mixed Connection Layout

Low-lead bronze resists corrosion and meets potable water safety standards for long-term installation. The mixed FNPT, MNPT and cup ends allow direct transition between threaded pipe and soldered copper without extra adapters. This reduces potential leak points and simplifies the joint layout in tight spaces.

Questions about this item

Will the 466 psi pressure rating hold up if the line runs hot at 200 °F all day?

Yes, the tee is rated for 466 psi at up to 200 °F, so continuous hot-water service stays within its design limits.

What pipe and tube must I already have to connect the FNPT, MNPT and cup ends?

You need 3/4 in NPT-threaded pipe for the FNPT and MNPT sides and 3/4 in copper tube (7/8 in OD) for the sweat cup.

Can I join this low-lead bronze tee to my existing standard bronze fittings without galvanic issues?

Both are bronze alloys, so they are galvanically compatible in potable-water systems.
