Expansion Isolation Pipe Plug
Expansion Isolation Plugs Offer Simple, Safe & Quick Installation with Minimal Torque -
Available for Sale or to Rent
USA Industries' uniquely designed Heavy Duty Isolation Pipe Plug eliminates the need to weld on end caps or plates for isolation. All pipe plugs are designed for simple and safe installation. As you tighten the isolation plug's nut, the metal on both ends of the seal ring compress and force the seal to expand. This process creates a tight seal against the inside of the pipe.
To use, simply install into the open end of the pipe or tube and tighten the compression nut(s) to expand the seal element. In-stock pipe plugs ship the same day.

- We offer standard and custom configurations to suit your specific application
- Manufactured under a Quality Assurance Program certified to ISO 9001:2015
- Engineering expertise to help you develop other non-standard sizes, configurations and applications
A SPECIAL WORD OF CAUTION:
Pressure testing can be an extremely hazardous operation and safety precautions should be strictly adhered to. All connections, valves, flanges and other fittings should be checked for suitability to test pressure. Verify the line ID & Plug Range match. Most importantly - NEVER stand or pass in front of any test plug or other enclosure while test is in progress. If plug discharges during a test, serious injury or death could occur.
