45-Degree Wye for Potable Water
This low-lead bronze wye joins three half-inch copper tubes in a 45-degree branch layout. It is designed for sweat connections on potable water lines. The fitting meets low-lead material requirements for drinking water systems.
Installers running copper supply lines
Plumbers needing a 45-degree branch on half-inch copper tube will use this wye. It is not for installers who require a straight tee, a different branch angle, or a fitting sized for larger or smaller tube diameters.
45-degree branch angle
The single specification that determines fit is the 45-degree wye configuration. A straight tee or any other angle will not produce the same flow direction or pipe routing in the assembly.

Questions about this item
What does the 45-degree wye angle mean for flow direction?
The 45-degree wye angle directs flow between the three cup connections at a 45-degree offset, allowing smoother directional changes in copper piping systems.
What copper tube size and outer diameter does each cup connection accept?
Each of the three cup connections accepts 1/2 inch copper tube size with a 5/8 inch tube outer diameter for sweat soldering.
How is this low-lead bronze wye installed, and what step is often missed?
Clean and flux the 5/8 inch tube ends and cup interiors, insert fully, then apply heat evenly to draw solder into all three joints; skipping thorough cleaning causes leaks.
