Description
ABS DWV Reducing Closet Flange (SPG)
ABS DWV Reducing Closet Flanges provide a secure toilet mounting connection while transitioning to a smaller ABS DWV pipe size through a spigot-style connection.
Featuring a spigot (SPG) connection, this reducing closet flange is designed to support a toilet at floor level while connecting into a compatible ABS DWV hub or fitting below. The reducing configuration allows the closet connection to transition to a smaller nominal pipe size, while the spigot end can provide a compact fitting-to-fitting installation without requiring an additional coupling. Manufactured for ABS DWV service, it meets recognized standards including ASTM D2661, CSA B181.1, and NSF Standard 14.

Connection Configuration
Spigot Connection
The spigot end is designed to fit into a compatible ABS DWV hub or fitting for solvent-cement installation.
Reducing Flange Connection
The reducing design transitions the closet outlet connection to a smaller nominal drain size, depending on the specific flange variation.
Reducing Closet Flange Design
This closet flange combines the toilet mounting interface, a spigot-style DWV connection, and a built-in pipe-size reduction in one fitting.
The spigot configuration can connect directly into a compatible ABS DWV hub, which may simplify installation where available space is limited or an additional coupling would be undesirable.
Because the flange is reducing, verify both the closet-side and drainage-side nominal sizes before ordering to ensure the fitting matches the intended toilet and piping layout.
Why Choose an ABS DWV Reducing Closet Flange?
Compact Reducing Connection
- Provides a built-in size transition

Installation
Verify the nominal closet-flange size, reduced drain size, and mating hub size before installation.
Position the flange at the proper elevation and orientation for the finished floor and toilet installation.
Clean and prepare the spigot end and mating ABS hub according to accepted ABS solvent-cement installation procedures.
Dry-fit the flange into the mating hub before applying solvent cement to confirm insertion depth, flange orientation, mounting alignment, and the intended size transition.
Apply compatible ABS solvent cement as required and fully seat the spigot into the mating hub while maintaining correct flange position.
Secure the flange and complete the toilet connection according to applicable plumbing requirements and manufacturer installation recommendations.
Our piping specialists can help review your toilet connection, reduced drain size, spigot connection, and ABS DWV compatibility before you order.

What is an ABS DWV reducing closet flange used for?
It is used to connect and support a toilet while transitioning the closet connection to a smaller ABS DWV drain size.
What does SPG mean?
SPG means spigot. The connection is designed to fit into a compatible ABS DWV hub rather than receiving pipe inside a socket.
What makes this closet flange reducing?
The fitting transitions between different nominal connection sizes, allowing the toilet connection to connect to a smaller downstream drain size.
Which size is reduced?
The exact reduction depends on the specific product variation. Verify both connection sizes before ordering.
Does the spigot connection fit directly into a hub?
Yes. The spigot end is designed to fit into a compatible ABS DWV hub connection.
Does the connection require solvent cement?
Yes. The spigot-to-hub connection is intended for compatible ABS solvent-cement installation.
Can the spigot design reduce the number of fittings needed?
Yes. In an appropriate layout, the spigot connection can fit directly into another hub and may eliminate the need for an additional coupling.
Is this fitting intended for pressure systems?
No. This fitting is intended for non-pressure drain, waste, and vent 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 is the maximum operating temperature?
The supplied product information specifies applications where operating temperatures do not exceed 140°F.
What should I verify before ordering?
Confirm the closet-flange size, reduced drain size, spigot size, mating hub size, finished-floor requirements, and compatibility with the intended ABS DWV system.
