  • Low-lead bronze keeps potable water safe

  • Three 3/4-inch cup connections simplify installation
  • Sweat fitting design creates strong leak-free joints
  • New condition ensures reliable performance out of the box

Potable-water sweat fitting

This low-lead bronze wye joins three 3/4-inch copper tubes in a 45-degree branch for potable-water systems. Each port accepts a 7/8-inch outer-diameter tube with a cup-style sweat connection. The fitting is new and compliant with low-lead requirements.

45-degree branch angle

The single specification that determines fit is the 45-degree wye angle; it fixes the branch direction relative to the run. All three ports share the same 3/4-inch copper tube size and cup connection type.

Three-port capacity

The coupling comfortably handles standard residential hot and cold distribution where a single 45-degree branch is needed. It runs out when the design calls for a different angle, a reducing branch or a threaded connection.

Questions about this item

How does the 45 degree wye angle affect flow when the fitting is installed in a copper pipe run?

The 45 degree angle creates a smoother directional change than a standard tee, reducing turbulence and pressure drop where a branch line joins the main run.

What does the low-lead bronze material mean for potable water installations?

Low-lead bronze meets Safe Drinking Water Act requirements, making this fitting legal for use in potable water supply lines.

What copper tube size and preparation does each of the three cup connections require?

Each cup accepts 3/4 inch copper tube with a 7/8 inch outside diameter; the tube ends must be cleaned, fluxed and soldered for a watertight sweat joint.
