1-1/2 inch ABS DWV Trap Adapter Plastic x Slip Joint

1-1/2 inch ABS DWV Trap Adapter – Slip Joint x Hub

The 1-1/2 inch ABS DWV trap adapter is engineered for secure and code-compliant connections in drainage waste and vent (DWV) systems. This fitting is designed to connect tubular slip joint tailpieces or traps to a solvent-welded ABS DWV system, making it ideal for lavatory, kitchen, or laundry installations.

Key Features

• Material: Acrylonitrile Butadiene Styrene (ABS) – lightweight and impact-resistant
• Connection Type: Slip Joint x Hub – enables transition from tubular trap to solvent-welded DWV pipe
• Size: 1-1/2 inch nominal
• Design Standard: Complies with ASTM D2661 and CSA B181.1 for DWV applications
• Configuration: Straight adapter, designed to accommodate compression-style nut and washer on the slip joint side

Installation Notes

Installation involves solvent welding the hub end to ABS pipe using approved ABS solvent cement. The slip joint side requires a slip nut and washer (typically provided with tubular trap kits) to create a mechanical seal to a tailpiece or trap outlet. This setup allows for convenient disassembly and access for cleaning or repairs without cutting pipe.

Typical Applications

This ABS trap adapter is commonly installed in bathroom vanities, kitchen sinks, utility sinks, and other residential drain systems. It serves as the transition fitting between a rigid DWV system and the removable P-trap assembly below a fixture outlet.

Performance and Durability

ABS is widely used in non-pressurized drainage applications due to its excellent dimensional stability, temperature resistance, and ease of handling. The slip joint design supports serviceability, while the solvent weld end ensures a permanent, watertight connection to the DWV system.

Did You Know?

ABS fittings do not require primer when solvent welding, unlike PVC, which simplifies installation time and reduces material requirements. This makes ABS a preferred choice for many contractors handling residential rough-in and finish plumbing work.

The 1-1/2 inch ABS DWV Trap Adapter offers durability, reliability, and compliance in one fitting—supporting fast, efficient installation and long-term performance in residential drainage systems.
