• Positive sealing in excess of 6500 PSI is achieved without special tooling or personnel training.
• Plug can be inserted to any depth of the tube sheet in order to avoid severely corroded areas on the tube sheet face.
• Design enables rapid implantation and fit into tight areas adjacent to the tube sheet/shell joint interface, baffle plates and internal dividers.
• One piece design enhances sealing characteristics by eliminating second potential leak path common to design found in two piece plugs.
• Wide sealing area contact zone ensures a positive seal while the gradual and symmetrical torque expansion eliminates thermal and mechanical shock to the tube sheet, commonly found with welding, impact due to hammering of tapered pins, and explosive insertion methods.
• Exclusive design allows installation of plugs at the face and back side of the tube sheet in order to prevent intrusion of shellside corrosives. With single plugging techniques accomplished on the face of the tube sheet, corrosives can enter the void created in the tube sheet, thereby exacerbating erosion and corrosion of the tube sheet ligaments
• TORQ N’ SEAL® Plugs are available to meet Nuclear ASME
  Sec. III or ISO 9002 QA specifications.

TORQ N’ SEAL® ...how it works!
The TORQ N’ SEAL® Plug is snapped onto the hex capture driver and inserted into the
tube ID, ensuring that the serrated sealing area is within the tube sheet. Applying the initial torque to the driver engages the anti-spin eccentric cam, locking the plug into the tube ID, thereby providing a torsional resistive force. As additional torque (in. lb.) is exerted, the drive screw threads into the plug body, pressing the tapered expansion ferrule into the reverse taper of the plug. These tapered surfaces combine to generate an enormous radial expansion force, swaging the serrated sealing area into the tube wall. A positive mechanical contact seal in excess of 6,500 psi is created.
