High Pressure Tube Plugs provide positive sealing in excess of 6,500 PSI (448.2 bar), making them ideal for high pressure applications such as feedwater heaters and other high pressure heat exchangers over 200 PSI (13.8 bar). As the most secure method to plug leaky tubes, they can also be used in low pressure applications for peace of mind.

Setup of the High Pressure Tube Plugs is fast and easy because the plug is installed without a hydraulic ram. With only a plug and hand torque wrench, the operator is ready to plug tubes. Simply insert the plug into the tube sheet of a leaking tube and expand with a standard 3/8” drive torque wrench. The plug will expand approximately 0.030” (0.76mm) to provide a positive mechanical contact seal. The one piece design allows for operators to easily plug tubes in tight spaces like hemispherical heads, baffle plates, and dividers.

It is good practice to install tube plugs that are the same as or a compatible material to the tube and tube sheet. The tube plugs are available in an array of materials to suit your needs: brass, carbon steel, stainless steel, titanium, monel, and copper nickel. We recommend puncturing the leaky tube with a One-Revolution Tube Cutter. This will ensure the tube is properly vented prior to plugging.
