Cast Aluminum Expansion Plugs are used to create barriers for pipes and tubes; and for creating an air-tight seal to purge short-length tube assemblies. To ensure proper fit for your application, choose a size ranging from 1.5” (38 mm) to 36” (914 mm). Cast aluminum plugs are quick and easy to install and use a wing nut that expands the rubber seal when placed in the pipe and tightened. Note: Special sizes available.
They are maintenance free and made of heavy-duty, non-corrosive cast aluminum with a natural rubber seal for a precision fit.
Pipe stems vary in diameter, according to the plug sizes and can be solid or with a vent. The pipe stems are threaded and have a removable cap. They vary in sizes ranging from 0.5 (13 mm) to 2” (50 mm).
Pressure Rating: Up to 8" (203mm) about 9 PSI. 8" or larger reduces the PSI. Example: A 30" (762mm) Plug would only handle about 3 PSI.
To convert PSI to Bar (European), 14.5 PSI equals 1 Bar.
