Reducing Wye for ABS Drain Systems

This Value Brand reducing wye connects three hub ends in a 4 in x 4 in x 3 in configuration. It is designed for DWV installations where a branch line reduces from a 4-inch main. The fitting suits plumbers and contractors working with schedule 40 ABS pipe.

Hub Connection Limits and Temperature Range

The hub-by-hub connection requires solvent cement and matched schedule 40 pipe for a watertight seal. Operating temperature must stay between -40 and 180 degrees F to maintain material integrity. The fitting meets ASTM D3965 cell class 32222 for consistent quality.

4 in x 4 in x 3 in Hub Sizing Decides Fit

The specific 4-inch by 4-inch by 3-inch hub dimensions determine whether this wye matches the piping layout. It will not work where all three connections share the same diameter or where a different reduction ratio is needed. Verify the exact hub sizes before purchase.

Questions about this item

Which hub size combination suits a 4-inch main line branching to a 3-inch line?

This reducing wye has a 4 in x 4 in x 3 in hub layout, so the straight run stays 4 inches and the branch drops to 3 inches.

What does the Schedule 40 rating mean once the fitting is installed?

Schedule 40 indicates the wall thickness and pressure class for standard drain, waste and vent service in ABS piping systems.

How does the ASTM D3965 cell class 32222 limit the fitting in practice?

Cell class 32222 defines the material quality grades for the ABS compound, confirming it meets the standard for the listed temperature range.
