Description
ABS DWV Reducing Double Sanitary Tee (ALL HUB)
ABS DWV Reducing Double Sanitary Tees provide two opposing sanitary branch connections while also transitioning between different nominal pipe sizes in non-pressure drain, waste, and vent systems.
Featuring hub connections on all openings, this fitting is designed to connect dual branch lines into a common ABS DWV main run while accommodating size reductions within the assembly. The double sanitary pattern allows opposite-side branch connections, while the reducing configuration helps connect different pipe sizes without requiring separate reducers 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
The main-run hub connections accept compatible ABS DWV pipe and form the primary piping path through the fitting.
Opposing Reducing Branches
The opposing branch hubs provide sanitary branch connections and may be different nominal sizes than the main run or each other, depending on the specific fitting variation.
Reducing Double Sanitary Tee Design
The reducing double sanitary tee combines two opposing sanitary branch connections with pipe-size transitions in one molded ABS fitting.
This configuration is useful where multiple branch lines of differing sizes need to connect to a common DWV run while maintaining sanitary-pattern flow transitions.
Depending on the specific size configuration, one or more hub connections may be reduced. Verify every connection size before ordering.

Installation
Verify every nominal hub size 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 entire assembly first to confirm main-run alignment, both branch orientations, and correct placement of each pipe size.
Apply compatible ABS solvent cement as required and fully seat each pipe into its corresponding hub while maintaining proper alignment.
Allow completed joints to cure according to the solvent cement manufacturer's recommendations before placing the drainage or vent system into service.
Our piping specialists can help review your main run size, both branch sizes, fitting orientation, and ABS DWV compatibility before you order.

What is an ABS DWV reducing double sanitary tee used for?
It is used to connect two opposing branch lines to a common ABS DWV run while transitioning between different nominal pipe sizes.
What does ALL HUB mean?
It means every pipe connection on the fitting is a hub-style connection designed to accept compatible ABS DWV pipe.
What makes this fitting reducing?
One or more hub connections are a different nominal size from the others, allowing the fitting to transition between different ABS DWV pipe sizes.
What makes this a double sanitary tee?
It has two opposing sanitary-pattern branch connections entering a common main piping run.
Which connections are reduced?
The reduced connections depend on the specific size variation. Verify the complete size configuration before ordering.
Does this fitting require solvent cement?
Yes. All 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 every hub size, which connections are reduced, both branch orientations, mating ABS DWV pipe sizes, and the intended non-pressure application.
