1-1/2 inch ABS DWV Cleanout Plug

1-1/2 inch ABS Plug – Threaded Termination for DWV Systems

The 1-1/2 inch ABS Plug is designed to provide a secure, removable seal within drain, waste, and vent (DWV) piping systems. Constructed from injection-molded acrylonitrile butadiene styrene (ABS), this plug is resistant to corrosion, abrasion, and chemical exposure commonly encountered in non-pressurized plumbing applications.

Typically installed in cleanouts, test tees, or system terminations, the plug’s threaded design ensures compatibility with female ABS threaded fittings. Its dimensional accuracy allows for repeated installation and removal where service access or temporary sealing is required.

Key Performance Attributes

• ✅ ABS Construction: Lightweight yet structurally rigid, suitable for use in gravity drainage applications.
• ✅ Threaded Male Connection: NPT-compatible threads provide a mechanical seal without permanent bonding.
• ✅ Corrosion and Chemical Resistance: Withstands degradation in sanitary waste systems and vent lines.
• ✅ Serviceable Design: Allows for access and reentry in cleanout assemblies or test points.

Technical Specifications

• Nominal Size: 1-1/2 inch
• Material: ABS (Acrylonitrile Butadiene Styrene)
• Connection Type: Male threaded (NPT)
• Application: DWV (Drain, Waste, and Vent systems)
• Standards: Meets ASTM D2661 and CSA B181.1 for ABS fittings

Installation Overview

Install into a corresponding ABS threaded fitting using PTFE tape or approved non-hardening thread sealant to enhance sealing performance. Avoid over-tightening, which can deform threads or compromise sealing surfaces. This plug is intended for use in gravity systems only and should not be pressurized.

Application Areas

This plug is used in residential and commercial DWV systems to cap off cleanouts, unused branches, or temporary access points. It is commonly found in wall cavities, floor drains, or vertical stacks where future serviceability is required.

Material Insight

ABS fittings are preferred in many drainage applications due to their ease of installation, dimensional stability, and resistance to microbial and chemical attack. The material performs well in low-temperature conditions and is not prone to corrosion, making it well suited for long-term DWV use.

The 1-1/2 inch ABS Plug provides a reliable sealing solution for threaded DWV terminations. Its removable design, chemical resistance, and adherence to code standards make it a dependable component in modern plumbing infrastructure.
