Sioux Chief Mfg Co. 882-35 Female Clean Test Plug 3.5in

Product Description

The SIOUX CHIEF MFG CO. 882-35 is a 3.5 inch female clean test plug designed to seal drain, waste, and vent (DWV) piping systems during pressure and leak testing. It threads into or seats inside 4 inch pipe to create a temporary, pressure-holding seal. The plug is fully corrosion proof, making it suitable for use in wet or chemically active pipe environments. Licensed plumbers and pipefitters use this fitting during rough-in inspections and DWV system testing to isolate sections of pipe before the system is put into service.

This clean test plug is appropriate for residential and light commercial plumbing applications where DWV piping requires temporary sealing during inspection or pressure testing. It fits inside 4 inch pipe, providing a reliable seal without the need for adhesives or special tools. The female thread design allows for quick installation and removal, supporting efficient workflow during new construction and remodel projects.
