1-1/2 inch ABS DWV Coupling – Built for Secure Sanitary Drainage Connections

The 1-1/2 inch ABS DWV Coupling is designed to connect two sections of 1-1/2 inch nominal diameter ABS pipe within non-pressurized drain, waste, and vent systems. Its solvent-weld hub ends deliver a reliable, rigid bond ideal for gravity-flow piping layouts in both new construction and retrofit applications.

Key Performance Features

• Material: Injection-molded from black ABS (Acrylonitrile Butadiene Styrene) for strength, dimensional stability, and low-temperature impact resistance.
• Joint Configuration: Hub x Hub solvent-welded ends for permanent pipe connections.
• DWV Application: Intended strictly for use in sanitary drainage and venting systems—not suitable for pressure piping.
• Corrosion and Chemical Resistance: ABS resists a wide range of household chemicals and does not rust or corrode, contributing to long service life.
• Standard Compliance: Meets or exceeds ASTM D2661 and CSA B181.1 specifications for ABS DWV fittings.

Installation Best Practices

For optimal performance and code compliance, ensure the following during installation:

• Dry-fit components before solvent welding to confirm alignment and orientation.
• Use ABS solvent cement only—primer is not typically required for ABS (verify local code requirements).
• Allow proper set and cure times as specified by the cement manufacturer before testing the system.

Typical Use Cases

This coupling is commonly installed in residential and light commercial DWV systems where two ABS pipe segments must be joined inline. It's ideal for under-sink assemblies, horizontal drainage connections, or vent pipe transitions where a reliable, permanent bond is required.

Did You Know?

ABS DWV systems are favored in cold-weather environments due to their ability to retain impact strength at low temperatures, which reduces the risk of cracking during installation or operation.

The 1-1/2 inch ABS DWV Coupling provides dependable performance for sanitary drainage applications. Its ease of installation, compatibility with standard ABS pipe, and proven material characteristics make it a reliable choice for professionals seeking durable and code-compliant fittings.
