Value Collection VS4.00 Nylon Pipe Test Plug 4 Inch

Product Description

The VALUE COLLECTION VS4.00 is a nylon hex pipe test plug designed for pressure testing and leak detection in drain, waste, and vent piping systems. The plug expands inside the pipe to create a temporary seal, allowing technicians to pressurize a section of pipe and verify integrity before final inspection. With a nominal size of 4 inches, an unexpanded diameter of 3.540 inches, and an expanded diameter of 4.250 inches, the VS4.00 fits standard 4-inch pipe schedules. Nylon construction resists corrosion and common chemicals encountered in plumbing test environments. This plug is a single-piece unit weighing 0.38 pounds.

The VS4.00 is used in residential and light commercial plumbing applications where temporary pipe sealing is required during rough-in pressure tests or final DWV system inspections. It is installed by licensed plumbers and plumbing contractors during new construction or remodel work. The hex-body design provides a positive grip surface for manual tightening or wrench engagement, making installation and removal straightforward in confined spaces.

Installation Notes

Installation is performed by licensed plumbers in accordance with applicable plumbing codes such as the IPC or local jurisdictional amendments. Before inserting the plug, confirm the pipe interior is clean and free of debris that could prevent a proper seal. Insert the plug to the correct depth and tighten the hex body to expand it against the pipe wall — do not overtighten, as nylon can crack under excessive torque. Remove the plug only after depressurizing the system fully.
