Description
ABS DWV P-Trap W/ Union Joint (HUB x HUB)
ABS DWV P-Traps with Union Joint create a water seal to help prevent sewer gases from entering occupied spaces while providing a removable connection for easier cleaning and maintenance.
Featuring hub connections on both ends and a built-in union joint, this fitting is designed for non-pressure ABS drain, waste, and vent systems. The curved trap body retains water to form the trap seal, while the union joint allows the trap assembly to be disconnected without cutting the adjoining piping. This can simplify installation, inspection, cleaning, and future maintenance. Manufactured for ABS DWV service, it meets recognized standards including ASTM D2661, CSA B181.1, and NSF Standard 14.

Connection Configuration
Hub Inlet & Outlet
The two hub connections accept compatible ABS DWV pipe and are designed for solvent-cement installation.
Built-In Union Joint
The union joint allows the trap assembly to be disconnected from the piping system for cleaning, inspection, or maintenance without cutting the pipe.
P-Trap & Union Design
The curved P-trap body retains a small amount of water after drainage, forming a trap seal between the fixture and sanitary drainage system.
This water barrier helps prevent sewer gases from traveling backward through the drainage line into occupied areas.
The integrated union joint adds serviceability by allowing the trap to be removed and reinstalled when access is required.

Installation
Verify both nominal hub sizes and confirm that the P-trap configuration is appropriate for the intended fixture and DWV piping layout.
Position the union joint so it remains accessible after installation and sufficient clearance is available for loosening, removal, and reassembly.
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 trap and adjoining piping before applying solvent cement to confirm proper orientation, trap positioning, and access to the union joint.
Apply compatible ABS solvent cement as required and fully seat each pipe into its corresponding hub while maintaining correct alignment.
Assemble and tighten the union joint according to the manufacturer's instructions. Allow completed solvent-cement joints to cure before placing the drainage system into service.
Our piping specialists can help review your trap size, fixture connection, union access, drain layout, and ABS DWV compatibility before you order.

What is an ABS DWV P-trap with union joint used for?
It creates a water seal in a fixture drain while providing a removable union connection that makes the trap easier to disconnect for cleaning or maintenance.
What does HUB x HUB mean?
It means both pipe connections are hub-style connections designed to accept compatible ABS DWV pipe.
What is the purpose of the union joint?
The union joint allows the trap assembly to be disconnected and removed without cutting the adjoining ABS piping.
How does the P-trap help block sewer gases?
The curved trap body retains water after drainage, creating a seal between the fixture and sanitary drainage system.
Can the trap be removed for cleaning?
Yes. The supplied product description identifies a built-in union joint intended to simplify removal, cleaning, and maintenance.
Should the union joint remain accessible?
Yes. Install the trap so there is sufficient clearance to loosen and remove the union connection when future service is required.
Does this fitting require solvent cement?
Yes. The hub connections are intended for compatible ABS solvent-cement installation. The union joint remains removable.
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 both hub sizes, fixture-drain size, trap configuration, union-joint access, mating ABS DWV pipe size, and intended non-pressure application.
