Sioux Chief 876-RS Series Solid Brass DWV Test Plug, Square-Raised Head

Sioux Chief 876-RS Series Solid Brass DWV Test Plug, Square-Raised Head

The Sioux Chief 876-RS Series is a solid brass, square-raised test plug engineered to pressure-test drain, waste, and vent (DWV) lines and seal cleanout openings during rough-in and inspection work. Available in 3" and 3-1/2" sizes, the series lets installers match the plug to the pipe diameter specified on the job. Solid brass construction withstands repeated pressure cycles, while the raised square head stays visible and easy to grip even after surrounding concrete, tile, or flooring work is complete. Plugs ship 10 EA per carton for stocking multiple rough-in locations on a single job.

Key Features

• Durable Construction: Solid brass resists corrosion and withstands the repeated pressure cycles common during plumbing rough-in testing, helping the plug hold a reliable seal test after test.
• Square-Raised Head Design: Sits above the surrounding surface, making the plug easy to locate, grip, and remove after concrete, tile, or flooring work covers the surrounding area.
• Reliable Cleanout Sealing: Seats securely in cleanout and test openings to help installers maintain a tight seal while a DWV line is under test pressure.
