Metal Expansion Plugs

Metal Expansion Plugs provide a superior seal without causing tube damage or ovaling of the tubesheet hole

Our Metal Expansion Plugs can provide a seal up to 4000 PSI and 1200 Degrees F. In less than one minute, the Metal Expansion Plug can be installed or removed using a standard wrench or socket. These plugs require only 20-60 ft. lbs. of torque to install depending on material and can be manufactured from any material specified.

USA Industries is a leader in offering tube plug solutions to users in the oil & gas, chemical and power industries. We have more than 500,000 tube plugs in stock and ready to ship, and our production capabilities exceed 5,000 plugs per day, more than 20 materials and any coatings you may require.

For best results with sealing tubes without damaging tubesheets, be sure to use the correct size tube plugs (based on tube O.D. and gauge using our chart below). When ordering tube plugs, please keep in mind that the tube plug and the tube metal should always match. Please contact us if you have any questions about our tube plugs or if you require more information.

A SPECIAL WORD OF CAUTION: USA Industries highly recommends you use our One Rev Internal Tube Cutter to puncture the tube before installing any plug to ensure that pressure cannot build up in the tube and cause the plugs to loosen or blow out.
