Description
ABS DWV 45 Reducing Street Wye (SPG x HUB x HUB)
ABS DWV 45 Reducing Street Wyes provide a smooth 45-degree branch connection with a street-style spigot end while also transitioning between different nominal pipe sizes.
Featuring a spigot (SPG) connection on the branch side and two hub connections on the main run, this fitting is designed for non-pressure ABS drain, waste, and vent systems that require both a gradual branch transition and a size reduction. The street-style spigot connection can fit directly into a compatible ABS DWV hub, while the reducing configuration can eliminate the need for an additional reducer 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 Hubs
The two hub connections form the primary ABS DWV piping run and accept compatible ABS pipe for solvent-cement installation.
Reducing Street Branch
The branch uses a spigot connection and may be a different nominal size than the main run, depending on the specific fitting variation.
45 Reducing Street Wye Design
This fitting combines three useful functions in one molded ABS component: a 45-degree wye branch, a street-style spigot connection, and a pipe-size reduction.
The branch enters the main run at approximately 45 degrees to support smoother drainage flow, while the spigot end can connect directly into a compatible ABS DWV hub fitting.
The reducing configuration allows different pipe sizes to be connected within the same fitting, helping simplify compact or space-sensitive piping layouts.

Installation
Verify all three connection sizes before installation and identify which connection provides the size reduction.
Cut all mating ABS pipe ends square and remove burrs. Clean and prepare the pipe, hub, spigot, and mating fitting surfaces according to accepted ABS solvent-cement installation procedures.
Dry-fit the complete assembly before applying solvent cement to confirm branch orientation, flow direction, proper size transition, and seating of the spigot into the mating hub.
Apply compatible ABS solvent cement as required. Fully seat the main-run pipe into each hub and the spigot branch into its compatible mating hub fitting 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, street connection, and ABS DWV compatibility before you order.

What is an ABS DWV 45 reducing street wye used for?
It is used to create a gradual 45-degree branch connection while transitioning between different ABS DWV pipe sizes and providing a direct spigot-to-hub connection.
What does SPG x HUB x HUB mean?
It means the fitting has one spigot connection and two hub connections.
Which connection is the spigot end?
The supplied product information identifies the branch side as the spigot connection, with hub connections on the two main-run ends.
What makes this fitting reducing?
At least one connection is a different nominal size from another connection, allowing the fitting to transition between different ABS DWV pipe sizes.
What makes this a street wye?
The spigot branch can connect directly into a compatible hub fitting without requiring an additional coupling between fittings.
What angle does the branch enter the main run?
The branch enters at approximately 45 degrees.
Which connection is reduced?
The reduced connection depends on the specific size variation. Verify all listed connection sizes before ordering.
Does this fitting require solvent cement?
Yes. The hub and spigot 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.
What should I verify before ordering?
Confirm all three connection sizes, which connection is reduced, branch orientation, location of the spigot end, mating hub compatibility, and intended non-pressure ABS DWV application.
