Torq N’ Seal® Heat Exchanger Tube Plugs

TORQ N’ SEAL® Heat Exchanger Tube Sheet Plug

Engineered tube plugs for heat exchangers and condensers with CRN#

Easy Installation with no special tooling required.



The TORQ N’ SEAL high pressure heat exchanger tube plug is a solid one piece plug that can be inserted to any depth of a leaking tube / tube sheet and installed by hand, providing unmatched flexibility and ease of use. The plug will expand approximately 35 mils (.035″) to provide a positive mechanical contact seal and are rated up to 7,000 psi after being rigorously tested.

The TORQ N’ SEAL® Heat Exchanger Plug can be used in high or low pressure applications such as feedwater heaters, moisture separator reheaters, preheaters, condensers, coolers, fin-fan coolers or any other tubed heat exchanger.

  • 7,000 psi. Positive sealing in excess of 7,000 PSI.
  • NO Special Tooling or personnel training.
  • Variable Installation Depth. Plug can be inserted to any depth of the tube sheet in order to avoid severely corroded areas on the tube sheet face.
  • Quick Installation. Torq N’ Seal® plugs can be installed in just seconds, the only tool you need is a 3/8″ square drive torque wrench.
  • Fit Into Tight Areas. 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, a common problem in the design of two piece plugs.
  • Wide Sealing Area contact zone ensures a positive seal.
  • NO Tube Sheet Damage. 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 shell side 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
  • Nuclear ASME Sec. III and ISO 9001:2015 QA Specifications

The Pop-A-Plug tube plugs and CPI Perma Plugs require special tooling to install – which are at a minimum, hydraulic ram package and plug positioner with pull rod assembly
