Connection Configuration
Hub Connection
One hub accepts compatible ABS DWV pipe for a permanent solvent-cement connection to one side of the drainage system.
Opposite Hub Connection
The second hub accepts compatible ABS DWV pipe on the opposite side, while the union body provides a point where the assembly can be disconnected for service.
Construction Details
The union is manufactured from virgin ABS polymer material suitable for molded fittings and ABS drainage systems.
Both hub ends are designed for compatible ABS solvent-cement installation, while the union body allows the connected piping sections to be separated without cutting the pipe.
This configuration is useful where future maintenance, replacement, or modification of drainage components may be required.

Installation
Verify the nominal hub size before installation and confirm compatibility with the intended ABS DWV pipe.
Cut both ABS pipe ends square and remove burrs. Clean and prepare the pipe and hub surfaces according to accepted ABS solvent-cement installation procedures.
Apply compatible ABS solvent cement as required, then fully seat each pipe into its corresponding hub while maintaining proper alignment.
Assemble the union connection according to manufacturer recommendations and make sure the union remains accessible for future service or disassembly.
Our piping specialists can help review your pipe size, installation layout, service requirements, and ABS DWV compatibility before you order.

What is an ABS DWV union used for?
It is used to connect two sections of compatible ABS DWV pipe while providing a convenient point where the piping can be disconnected for maintenance or modification.
What does HUB x HUB mean?
It means both ends are hub connections designed to accept compatible ABS pipe for solvent-cement installation.
Why use a union instead of a standard coupling?
A union provides a serviceable connection that can be disconnected, while a standard solvent-cement coupling creates a permanent connection between the pipe sections.
Can the union be disconnected after installation?
Yes. The union design is intended to provide a serviceable disconnect point while the hub connections remain attached to the ABS piping.
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 specifically 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 standards are referenced?
The supplied product information references ASTM D3965, ASTM D2661, CSA B181.1, and NSF Standard 14.
What should I verify before ordering?
Confirm the nominal hub size, mating ABS pipe size, available installation space, service-access requirements, operating temperature, and intended drainage application.
