Sioux Chief 881-52 Mechanical Test Plug 2 Inch

Product Description

The SIOUX CHIEF 881-52 is a 2-inch mechanical test plug used to temporarily seal drain, waste, and vent (DWV) piping during pressure and leak testing. Plumbers and pipefitters insert the plug into an open pipe end or cleanout, then expand or lock it in place to create a reliable seal that holds system test pressure. This tool is standard equipment for rough-in inspections on residential and commercial plumbing systems where code requires a witnessed pressure test before walls are closed.

The 881-52 is suited for 2-inch DWV pipe stacks, branch drains, and cleanout openings. It is commonly used during new construction and remodel rough-ins when air or water pressure tests are required prior to inspection. The plug is removed after the test and can be reused across multiple jobs, making it a practical addition to a plumber's test kit.

Key Features

• Fits 2-inch pipe openings for DWV pressure and leak testing
• Mechanical expansion design creates a secure, temporary seal
• Reusable construction supports repeated use across multiple test scenarios
• Compact size for easy transport in a standard tool bag or test kit

Compatibility

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable plumbing codes such as the IPC or local authority requirements. Shut off or isolate the piping system before inserting the test plug, and ensure no downstream fixtures or valves are under unintended pressure during the test. Do not exceed the rated test pressure for the plug or the pipe system. Remove and inspect the plug after each use before storing.
