Description
ABS DWV Repair Coupling (HUB x HUB)
ABS DWV Repair Couplings provide a practical way to join or repair sections of ABS piping in non-pressure drain, waste, vent, sewer, and general drainage systems.
Featuring hub connections on both ends and a no-stop internal design, this coupling can slide farther onto compatible ABS pipe to simplify repair and modification work where pipe movement is limited. Manufactured for ABS DWV service, it meets recognized standards including ASTM D2661, CSA B181.1, and NSF Standard 14.

Connection Configuration
Hub Connection
One hub accepts compatible ABS DWV pipe for a permanent solvent-cement connection on one side of the repair.
Opposite Hub Connection
The second hub accepts compatible ABS DWV pipe on the opposite side. Because there is no internal stop, the coupling can slide over the pipe to assist with positioning during repair work.
No-Stop Repair Design
Unlike a standard coupling with an internal center stop, a repair coupling is designed without a stop between the two hubs.
This allows the coupling to slide farther over one pipe section during installation, making it easier to position between existing pipe ends where there is limited flexibility or movement.
Once properly positioned, the coupling can be centered over the repair area and solvent-cemented to both pipe sections according to approved ABS installation procedures.

Standards & Compliance
- ASTM D3965: ABS material requirements for pipe extrusion and molded fittings

Installation
Verify the nominal coupling size before installation and confirm compatibility with the intended ABS DWV pipe.
Cut out the damaged or unwanted pipe section as required, leaving clean, square pipe ends. Remove burrs and clean the mating surfaces.
Because the coupling has no internal stop, slide it fully or partially onto one pipe section as needed to create installation clearance.
Apply compatible ABS solvent cement according to manufacturer recommendations, reposition the coupling so it bridges both pipe ends, and ensure proper alignment before the joint sets.
Allow the 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 pipe size, repair layout, installation clearance, and ABS DWV compatibility before you order.

What is an ABS DWV repair coupling used for?
It is used to join or repair sections of ABS DWV pipe, especially where the existing piping has limited movement.
What makes a repair coupling different from a standard coupling?
A repair coupling has no internal center stop, allowing it to slide farther over the pipe during installation.
What does HUB x HUB mean?
It means both ends are hub connections designed to accept compatible ABS pipe for solvent-cement installation.
Why is the no-stop design useful?
It allows the coupling to slide over an existing pipe section so it can be repositioned across a repair joint after the replacement pipe is installed.
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 pipe size, repair location, available installation clearance, operating temperature, and intended non-pressure drainage application.
