3 inch ABS DWV Cleanout Adapter Fitting x Plastic

3-Inch ABS Cleanout Fitting – DWV Component for Accessible Drainage Maintenance

The 3-Inch ABS Cleanout Fitting is a component of non-pressurized drainage, waste, and vent (DWV) systems used to provide code-mandated access points for maintenance and inspection. This fitting is manufactured from injection-molded acrylonitrile butadiene styrene (ABS) conforming to ASTM D2661 and is designed for solvent-weld installation with compatible ABS Schedule 40 piping.

Its hub-style socket end allows for direct joining to piping or fittings using ABS solvent cement, providing a gas-tight and water-resistant seal. The upper cleanout port accepts a standard threaded plug (not included), enabling line access for rodding, flushing, or inspection without disassembling the system.

Product Features

• ✅ Nominal Size: 3 inches
• ✅ Material: ABS plastic, suitable for gravity DWV systems
• ✅ Connection Type: Hub (solvent-weld socket)
• ✅ Fitting Type: Cleanout with access port for threaded closure
• ✅ Temperature Range: Up to 180°F intermittent (non-pressurized)

Applicable Standards

• ASTM D2661 – ABS Schedule 40 DWV Fittings
• ASTM D3965 – Classification for Rigid ABS Compounds
• NSF/ANSI 14 – Certified for plastic piping system components (when marked)
• UPC and IPC compliant for use in residential and commercial DWV systems

Installation Guidelines

Install using appropriate ABS solvent cement per ASTM D2235. Pipe and fitting ends must be clean, dry, and chamfered before assembly. Apply even pressure during insertion and allow recommended cure time before testing the system. Ensure threaded cleanout plug is properly torqued and sealed using PTFE tape or thread compound.

Typical Applications

Used in horizontal and vertical DWV runs to provide access points at required intervals or near fixture branches. This fitting is typically installed at the base of stacks, building drains, or changes in direction exceeding 135°, as specified by local plumbing codes.

Material Characteristics

ABS is lightweight, resistant to a wide range of household and industrial chemicals, and suitable for indoor or above-grade use. Not recommended for use in pressurized systems or systems transporting hot water continuously above 140°F.
