Description
ABS DWV 90 Reducing Closet Street Elbow (HUB x SPG)
ABS DWV 90° Reducing Closet Street Elbows provide a compact 90-degree directional change while transitioning between different pipe sizes in non-pressure drain, waste, vent, sewer, and sanitary drainage systems.
Featuring a hub connection on one end and a spigot (SPG) connection on the other, this reducing street elbow is commonly used in toilet and water-closet installations where both a size transition and a tight directional change are required. The street-style spigot end allows direct connection into a compatible ABS DWV hub fitting, helping reduce overall assembly length. Manufactured for ABS DWV service, it meets recognized standards including ASTM D2661, CSA B181.1, and NSF Standard 14.

Connection Configuration
Hub Connection
The hub end accepts compatible ABS DWV pipe and forms one side of the reducing connection.
Spigot Connection
The spigot end is designed to fit directly into a compatible ABS DWV hub fitting, allowing a close-coupled connection while completing the size transition.
Reducing Street Elbow Design
This fitting combines three useful functions in one molded ABS component: a 90-degree turn, a pipe-size reduction, and a street-style spigot connection.
The reducing configuration allows the fitting to transition between different nominal pipe sizes, while the street end can connect directly into another compatible hub fitting without requiring an additional coupling.
This makes the fitting especially useful in compact toilet and water-closet drainage layouts where installation space is limited.

Installation
Verify the nominal hub and spigot sizes before installation and confirm which connection corresponds to the larger and smaller ABS DWV size.
Cut the mating ABS pipe 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 assembly first to confirm the required 90-degree orientation, size transition, and street connection before applying solvent cement.
Apply compatible ABS solvent cement as required, fully seat the pipe into the hub and the spigot into the mating hub fitting, then maintain proper alignment while the joints set.
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 larger and smaller pipe sizes, toilet drainage layout, fitting orientation, and ABS DWV compatibility before you order.

What is an ABS DWV 90° reducing closet street elbow used for?
It is used to create a 90-degree directional change while transitioning between different ABS DWV pipe sizes, commonly in toilet and water-closet drainage installations.
What does HUB x SPG mean?
HUB means one end accepts compatible ABS DWV pipe, while SPG means the opposite end is a spigot designed to fit directly into a compatible hub fitting.
What makes this a reducing fitting?
The two connection ends correspond to different nominal sizes, allowing the fitting to transition from one ABS DWV pipe size to another.
What makes this a street elbow?
The spigot end allows the fitting to connect directly into another compatible hub fitting without requiring an intermediate pipe section or additional coupling.
Why is it called a closet elbow?
Closet elbows are commonly used in toilet or water-closet drainage layouts where the fixture drain needs to turn before connecting to the sanitary drainage system.
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.
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 the nominal hub and spigot sizes, direction of the size reduction, required 90-degree orientation, mating ABS components, and intended non-pressure drainage application.
