Shaw mechanical expansion plugs are an integral part of the testing process as they seal pipes, creating low pressure inside the system. These Turn-Tite Series mechanical plugs do not rust, preventing damage to the pipe or vent they are used in.

The steel hardware is electroplated with zinc to improve corrosion resistance and strength of the plugs.
Yes, neoprene seals have a high expansion rate (10 - 12%) that allows superior heat resistance at temperatures up to 275 degrees F.
These mechanical expansion plugs are designed to close off pipes, receptacles and open conduits which are subjected to high pressure due to the fluid present in them.
