Fin-fan coolers have their tube sheets located in a water box on the front of the unit. The box has hand access holes located opposite all of the tubes, however, the access hole may be 6 – 12” from the face of the tube sheet. In the past, plugging leaking tubes has always been difficult.
The Torq N Seal® Top Hat plug was designed to pass through the water box of a fin-fan cooler while positioned on the end of an extended hex drive. The “top hat” shoulder allows the installer to accurately position the Torq N Seal® Plug into the tube without a visual reference by sliding the plug into the tube until the shoulder makes contact with the tube end indicating to that the Torq N Seal® Plug is seated correctly and ready to be torqued. |
