The VALUE COLLECTION 51031 is a snap-style pressure test plug designed for sealing pipe openings during pressure testing procedures. The plug features a 4-inch outer diameter and measures 1.1875 inches in length. It installs quickly without tools, using a snap-fit mechanism to create a secure, temporary seal in pipe ends or fittings. Plumbers, pipefitters, and mechanical contractors use this type of plug to isolate sections of pipe during hydrostatic or air pressure tests. The compact length and snap-fit design allow for fast installation and removal, keeping testing workflows efficient on the job site.
This pressure test plug is suited for residential and commercial plumbing, mechanical piping, and drain-waste-vent systems where temporary isolation is needed during inspection or pressure testing. It is commonly used during rough-in inspections and before final system commissioning. The 4-inch OD size fits standard 4-inch pipe openings.
Designed as an OEM-style replacement and general-use pressure test plug for standard 4-inch pipe ends in plumbing and mechanical piping systems.
This plug is installed by licensed plumbers or pipefitters during pressure testing stages of a project. Verify the pipe end is clean and free of debris before seating the plug to ensure a proper seal. Always depressurize the system fully before removing the plug. Follow applicable IPC and local plumbing code requirements for test pressure limits and duration.
