Value Collection AP03.50 Aluminum Expansion Plug 9 Psi

Product Description

The VALUE COLLECTION AP03.50 is an aluminum expansion plug designed to seal pipe openings by expanding outward against the inner wall of the pipe. The plug installs in its unexpanded state at 3.503 inches and expands to 3.700 inches to form a secure mechanical seal. It is rated for a maximum working pressure of 9 psi. The 1/2-inch stem allows the expansion mechanism to be driven or tightened with standard hand tools. This type of fitting is used by plumbers, pipefitters, and maintenance technicians to cap, test, or isolate sections of piping systems.

This expansion plug is suited for use in pipe testing, system isolation, and drain or cleanout sealing applications where a removable, pressure-rated cap is required. Its aluminum construction makes it appropriate for use with non-ferrous piping, drainage systems, and light-duty pressure applications. A single plug is included per package.

Key Features

• Expands from 3.503 inches to 3.700 inches for a tight mechanical seal against pipe walls
• Rated to 9 psi maximum working pressure
• 1/2-inch stem diameter for use with standard wrenches or drivers
• Aluminum construction resists corrosion in drainage and low-pressure service environments
• Single-piece design with no additional hardware required for installation

Compatibility

Designed as an OEM-style replacement or service plug for pipe openings with an internal diameter in the range of 3.503 to 3.700 inches, typical of nominal 3.5-inch pipe applications in plumbing and drainage systems.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Before installing or removing the plug, depressurize and drain the affected pipe section completely. Use a wrench on the 1/2-inch stem to expand the plug until it seats firmly against the pipe wall. Do not exceed the 9 psi rated working pressure during testing or service operations.
