Description
ABS DWV 45 Reducing Wye (HUB x HUB x HUB)
ABS DWV 45 Reducing Wyes provide a smooth 45-degree branch connection while transitioning between different nominal pipe sizes in non-pressure drain, waste, and vent systems.
Featuring hub connections on all three ends, this fitting is designed to connect compatible ABS DWV piping while introducing a branch line into the main run at a gradual 45-degree angle and accommodating a pipe-size reduction. The reducing wye configuration helps support efficient drainage flow while minimizing abrupt directional changes and can reduce the need for a separate reducing fitting in certain layouts. Manufactured for ABS DWV service, it meets recognized standards including ASTM D2661, CSA B181.1, and NSF Standard 14.

Connection Configuration
Main Run Connections
Two hub connections form the primary ABS DWV piping run and accept compatible pipe for solvent-cement installation.
Reducing 45-Degree Branch
The third hub forms the branch connection and may be a different nominal size than the main run, depending on the specific fitting variation.
45 Reducing Wye Design
The 45 reducing wye combines a gradual branch connection and pipe-size transition in a single molded ABS fitting.
The branch enters the main run at approximately 45 degrees, helping support smoother drainage flow than a more abrupt perpendicular connection.
Because the fitting is reducing, one or more hub connections may differ in nominal size. Verify the full connection configuration before ordering.

Installation
Verify all three nominal hub sizes before installation and identify which connection or connections provide the size reduction.
Cut all mating ABS pipe ends square and remove burrs. Clean and prepare the pipe and hub surfaces according to accepted ABS solvent-cement installation procedures.
Dry-fit the complete assembly before applying solvent cement to confirm branch direction, flow orientation, and proper placement of each pipe size.
Apply compatible ABS solvent cement as required and fully seat each pipe into its corresponding hub while maintaining correct alignment.
Allow completed joints to cure according to the solvent cement manufacturer's recommendations before placing the drainage system into service.
Our piping specialists can help review your main-run size, branch size, reduction, fitting orientation, and ABS DWV compatibility before you order.

What is an ABS DWV 45 reducing wye used for?
It is used to connect a branch line into a main ABS DWV piping run at approximately a 45-degree angle while also transitioning between different pipe sizes.
What does HUB x HUB x HUB mean?
It means all three connections are hub-style connections designed to accept compatible ABS DWV pipe.
What makes this fitting reducing?
At least one hub connection is a different nominal size from another connection, allowing the fitting to transition between different pipe sizes.
Which connection is reduced?
The reduced connection depends on the specific size variation. Verify all three connection sizes before ordering.
Why use a 45 wye instead of a standard tee?
A wye introduces the branch at a more gradual angle, which supports smoother directional flow in appropriate drainage applications.
What angle does the branch enter the main run?
The branch enters at approximately 45 degrees.
Does this fitting require solvent cement?
Yes. All three hub connections are intended for compatible ABS solvent-cement installation.
Is this fitting intended for pressure systems?
No. This fitting is intended for non-pressure drain, waste, vent, sewer, and general drainage applications.
Can it be used for compressed air or gas?
No. The supplied product information states that ABS DWV fittings are not intended for transporting compressed air or gas.
Can this fitting be used for pressure testing?
No. The supplied product information states that ABS DWV fittings should not be used for pressure testing.
What should I verify before ordering?
Confirm all three hub sizes, which connection is reduced, branch orientation, main-run direction, mating ABS DWV pipe sizes, and intended non-pressure drainage application.
