TORQ N’ SEAL® Removal Procedure

Click here for printable PDF version

Torq N’ Seal® heat exchanger tube plugs are designed to create a permanent, mechanical contact seal. However, there are some circumstances where the plugs need to be removed. For instance, when it comes time to re-tube a heat exchanger the plugs can be removed so the leaking tube can be pulled out.

Remove the Plug

Use the Crescent Wrench to slowly turn down the nut and washer clock-wise which will drive the stainless steel collar into the tube sheet face. Continue turning the nut and the plug will be pulled free as the threaded rod is retracted through the stainless steel collar. When the jacking assembly shifts suddenly, the plug is free and you can simply pull it out with the assembly.
