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.
