Cast Aluminum Expansion Plugs

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.

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.

Not bad. They secure well, but forget about using them to purge into. The cast aluminum is rough, and the threaded stud uses an oddball diameter/thread pitch that I have yet to find a way to adapt a quick connect to in order to blow argon through it. They come with a threaded plastic cap, which I remove and replace with some painters tape and pop a small hole to purge out of on the other end of the line.
