The OATEY 0323004 is a 4-inch cleanout adapter with plug designed for drain and waste plumbing systems. This fitting provides a removable access point in a drain line, allowing plumbers and service technicians to snake or inspect the pipe without cutting into the run. The plug threads into the adapter to seal the cleanout opening during normal operation and can be removed quickly when service access is needed. At 0.5 pounds, it is a lightweight, easy-to-handle fitting suited for both new construction and retrofit installations.
This cleanout adapter is used in residential and light commercial drain, waste, and vent (DWV) plumbing applications. It is typically installed at grade level, in walls, or at the base of a stack where routine maintenance access is required. Licensed plumbers and pipefitters install this type of fitting during rough-in or as a service upgrade to an existing drain line.
Designed as an OEM-style replacement or new-installation fitting for 4-inch drain, waste, and vent plumbing systems in residential and light commercial construction.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and ensure the drain line is clear before cutting into an existing run to install this fitting. Use the appropriate solvent cement or thread sealant as required by the pipe material and local code. Do not overtighten the plug, as this can damage the threads and make future access difficult.
