1-1/2 inch ABS DWV Cap

1-1/2” ABS DWV Cap – Engineered for System Integrity in Drainage Networks

The 1-1/2” ABS DWV Cap provides a secure termination point for non-pressurized piping systems in drainage, waste, and vent (DWV) applications. Commonly used to seal unused pipe ends or facilitate future access, this solvent-weld fitting ensures consistent performance and system reliability.

Molded from acrylonitrile butadiene styrene (ABS), this cap offers excellent dimensional stability and resistance to impact, chemicals, and thermal deformation. It is suitable for both horizontal and vertical installations and performs reliably in above-ground residential and light commercial systems.

Product Features

• ✅ Solvent Weld Design – Ensures a permanent, watertight bond to ABS pipe using standard solvent cement for DWV applications.
• ✅ Impact-Resistant ABS – Durable under job site handling and long-term service conditions.
• ✅ Corrosion-Resistant – Will not rust or degrade when exposed to common household waste materials or vent gases.
• ✅ Consistent Wall Thickness – Maintains uniformity for a flush, secure fit across pipe assemblies.
• ✅ ASTM-Compliant – Manufactured to meet applicable standards for DWV fittings in ABS systems.

Technical Specifications

• Material: ABS (Acrylonitrile Butadiene Styrene)
• Nominal Size: 1-1/2 inch
• Connection Type: Hub (Socket) – solvent weld
• Application: Non-pressurized Drain, Waste, and Vent systems
• Compliance: Conforms to ASTM D2661 and CSA B181.1

Installation Guidelines

To install, clean both mating surfaces and apply ABS solvent cement as specified by local code. Insert the pipe into the hub until fully seated, and allow for full cure time per manufacturer's instructions. This cap is designed for permanent closure and should not be used where future disassembly is required unless installed with an accessible cleanout system.

Typical Applications

Used to cap pipe terminations in residential and light commercial DWV systems. Suitable for use in new construction, rough-ins, branch line terminations, and pressure testing of drainage systems (where permitted by code).

Field Tip

In vertical stacks, ensure the cap is properly braced or supported to prevent movement due to thermal expansion or mechanical stress during installation.

The 1-1/2” ABS DWV Cap offers a dependable termination solution for ABS piping systems, maintaining system integrity and facilitating compliance with DWV construction standards. Its solvent-weld design and impact-resistant material make it a durable, jobsite-ready component for drain and vent applications.
