1-1/2 inch ABS DWV Adapter – Solvent-Weld Transition Fitting for Drain, Waste, and Vent Systems

The 1-1/2 inch ABS DWV Adapter is a solvent-weld fitting used to transition between ABS piping and threaded system components in non-pressurized drain, waste, and vent systems. Manufactured from high-impact Acrylonitrile Butadiene Styrene (ABS), this adapter is suitable for both above-ground and below-ground installations where reliable, corrosion-resistant connections are required.

Designed to meet dimensional tolerances outlined in ASTM D2661 and CSA B181.1, this adapter provides a secure connection between 1-1/2 inch nominal ABS pipe and female-threaded fittings or cleanout plugs. Its use in residential and light commercial systems supports durable tie-ins at vertical stacks, horizontal branches, and cleanout access points.

Technical Specifications

• Material: ABS (Acrylonitrile Butadiene Styrene)
• Nominal Size: 1-1/2 inch
• Connection Type: Spigot x Male Pipe Thread (MPT)
• System Type: Non-pressurized DWV (Drain, Waste, and Vent)
• Compliance: ASTM D2661, CSA B181.1, IPC/UPC code compliant

Installation Guidelines

Connect to the ABS system using approved primer and solvent cement in accordance with ASTM D2235 procedures. For threaded connections, use a compatible thread sealant appropriate for ABS and the media conveyed. Proper torque should be applied to prevent over-tightening and potential thread failure. All joints should be tested per applicable plumbing codes after installation.

Typical Applications

Used in gravity-based drainage systems for fixture arm connections, vent terminations, or cleanout assemblies. This fitting is commonly installed in vertical stacks, wall cavities, and floor assemblies where pipe transitions or access provisions are required.

Material Considerations

ABS offers excellent impact resistance and dimensional stability under fluctuating temperature conditions. It is lightweight, non-corrosive, and easy to handle, making it a preferred choice in both new construction and renovation projects. The solvent-weld bond forms a rigid, permanent joint ideal for DWV use.
