There is a New, Easy Way to Seal Leaking Tubes!

Our signature tube plug is the standard model Torq N’ Seal® high pressure tube plug. This plug can be inserted to any depth of the tube / tube sheet and can be installed by hand, providing unmatched flexibility and ease of use. These plugs are rated up to 6,500 psi and have been rigorously tested. Please see our Torq N’ Seal Hydro / Helium Test Report for detailed information. We stock Torq N’ Seal® plugs in most common sizes and materials, but we are happy to custom make a plug to suit your specific requirements. Please view our Materials Data Sheet for more information. We are happy to answer any questions or comments, just give us a call at 201-641-2131, email us at, or use one of the website forms on the right side of the menu.

Torq N’ Seal® … How it works!!!

U.S. Pat. Nos. 5,289,851; 6,883,547 and 6,981,524, others pending

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.
