Nibco, Inc. 714RR-LF 1/2X3/4X1/2 Tee Bronze Cup FNPT Cup Reducing Tee

SKU CH-M04M-SBVRA

Bronze reducing tee with sweat, FNPT and sweat connections for potable water at up to 577 psi

  • Reducing design connects three different pipe sizes
  • Sweat copper ends simplify soldered installation
  • FNPT centre port accepts standard threaded fittings
  • Cast bronze body rated to 577 psi
  • Lead-free alloy approved for potable water systems

Reducing Tee for Potable Water

The NIBCO 714RR-LF is a cast bronze sweat fitting tee designed for potable water applications. It features a reducing configuration with Cup connections on both run ends sized for 1/2 inch copper tube and an FNPT branch connection for 3/4 inch pipe. This fitting joins dissimilar pipe sizes in a single junction.

Rated for Sustained Pressure

The bronze body is rated for a maximum operating pressure of 577 psi, maintaining structural integrity under continuous system load rather than only brief test spikes. Cast bronze construction resists dezincification and corrosion in potable water, ensuring the joint remains sound through thermal cycles and pressure fluctuations over long service life.

Replaces Threaded or Flanged Reducers

This tee replaces assemblies that would otherwise require separate reducing couplings and threaded tees, cutting joint count and potential leak paths. The jump is worth it when consolidating a 3/4 inch FNPT branch off a 1/2 inch copper main, eliminating the need for transition fittings on each leg. Builders needing a straight tee or different reduction ratio cannot use this configuration.

Questions about this item

How much pressure can the 714RR-LF reducing tee handle in a closed-loop heating system running all day?

The fitting is rated for a maximum operating pressure of 577 psi, so it will hold continuous service in typical residential hydronic loops without leaking or deforming.

What pipe and tools do I need on hand to install the 1/2-inch cup ends and the 3/4-inch FNPT branch?

You need 1/2-inch copper tube with a 5/8-inch outer diameter for the sweat cups, a 3/4-inch male NPT threaded pipe or adapter for the centre branch, flux, lead-free solder and a propane or MAPP torch for the sweat joints.

Will the cast-bronze body and mixed connections mate cleanly with older copper and galvanised pipe already in the house?

The bronze body resists dezincification and threads directly to legacy 3/4-inch NPT fittings, while the 1/2-inch sweat cups join existing 5/8-inch OD copper without dielectric concerns.
