IPS 83689 3-1/2-Inch Flush Mechanical Cleanout Repair Plug - Easy Flush Install

Overview

The IPS 83689 is a 3-1/2 inch flush mechanical cleanout repair plug designed for cast iron cleanouts with worn or stripped threads. A rubber gasket sits behind the threads, enabling an airtight seal even when the threaded surface is compromised. The plug is built to withstand backpressure up to 50 feet and installs completely flush with the pipe, reducing visible clutter and potential snag points in tight spaces. Each package includes an Allen wrench for quick setup. This model is proudly made in the United States.
