4" x 3" ABS 45 Reducing Wye (Hub x Hub x Hub)

4" x 3" ABS 45 Reducing Wye - Hub x Hub x Hub

The 4" x 3" ABS 45 reducing wye is designed for drain, waste and vent (DWV) plumbing systems that require a 3 inch branch connection from a 4 inch main line. The 45 degree branch angle promotes smooth gravity flow while reducing turbulence and maintaining proper drainage performance.

This fitting maintains a full size 4 inch straight run while reducing the branch outlet to 3 inches. The long sweep design helps support efficient waste flow and proper system slope in residential, commercial, and multi unit plumbing installations.
