1-1/2 inch ABS DWV Adapter Plastic x Female

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

The 1-1/2 inch ABS DWV Adapter is a solvent-weld transition fitting used to connect ABS pipe to threaded components within non-pressurized drainage systems. Manufactured from impact-resistant ABS (Acrylonitrile Butadiene Styrene), it is designed for gravity-flow DWV installations in accordance with IPC, UPC, and CSA plumbing standards.

Commonly used where system design requires a shift from hub-and-spigot pipe to male-threaded terminations, this adapter supports efficient tie-ins to cleanouts, mechanical equipment, or transition assemblies while maintaining code compliance and structural integrity.

Product Features

• Material Composition: High-impact ABS plastic rated for DWV service
• Nominal Size: 1-1/2 inch
• Connection Type: Hub (solvent weld) x Male Pipe Thread (MPT)
• Design Standard: Conforms to ASTM D2661 for ABS DWV fittings
• Temperature Rating: Suitable for non-pressurized drainage up to 140°F

Installation Guidelines

Install by applying an approved ABS solvent cement to both mating surfaces per ASTM D2235. Ensure surfaces are clean and properly aligned before bonding. For threaded connections, use a compatible thread sealant or PTFE tape rated for DWV applications. Do not overtighten threads, as ABS is subject to stress cracking under excessive torque. Allow for adequate curing time as specified by the cement manufacturer prior to system testing.

Application Scope

This fitting is commonly used in residential and light commercial drain and vent systems for branch lines, fixture tie-ins, and cleanout access points. It provides a reliable connection in gravity flow systems where code-mandated material and dimensional tolerances must be maintained.

Material Performance Insight

ABS is known for its impact resistance, dimensional stability, and ease of installation. It remains unaffected by soil conditions and is suitable for both above- and below-grade installations where UV exposure is not a concern. The adapter’s solvent-welded hub connection ensures a permanent bond, while the threaded end offers mechanical flexibility during assembly or future service.
