Test-tite 83594 Mechanical Test Plug with Screw and Zinc Nut 4 Inches Pipe 5 Psig Abs

Product Description

The TEST-TITE 83594 Mechanical Test Plug is a domestically manufactured pipe testing and blocking solution built for use in standard DWV (drain, waste, and vent) piping systems. Constructed from durable ABS plastic, this twist-style test plug is designed to create a reliable, leak-free seal inside a 4-inch pipe for pressure testing or temporary blockage during installation and inspection. The plug features a screw-and-zinc-nut mechanical expansion design, meaning it seats firmly against the inner wall of the pipe when tightened. This gives plumbers and pipefitters a secure, repeatable connection without the need for adhesives or special tools. The TEST-TITE 83594 is rated for a working pressure of 5 psig, which meets the requirements for standard DWV system pressure tests used in residential and light commercial plumbing applications. Plumbers use test plugs like this one during rough-in inspections to verify that a drain or vent system holds pressure before walls are closed and finishes are applied. The ABS construction makes it lightweight and resistant to many common drain chemicals, while also being compatible with ABS and PVC DWV pipe. The mechanical expansion design allows for a tight fit and easy removal after testing is complete. This plug is a practical, code-compliant solution for plumbing contractors, service technicians, and inspectors who need a dependable way to isolate and test sections of drain, waste, and vent piping. Whether used for new construction or remodel work, the TEST-TITE 83594 delivers consistent performance in 4-inch pipe applications. It is domestically produced, making it a reliable choice for jobs that require American-made components.
