Step 0: Order the Correct Torq N’ Seal® Elastomer Condenser Plug
Identify your tube inner diameter (see Appendix 1 at bottom of page for Tube ID chart), then select the plug below with the appropriate range:
- TNS-ECP 3/4″ 14-16G — 0.580” – 0.640” (1.47 – 1.63 cm)
- TNS-ECP 3/4″ 18-22G — 0.625″ – 0.710″ (1.59 – 1.80 cm)
- TNS-ECP 7/8” 18-22G — 0.750” – 0.900” (1.90 – 2.29 cm)
- TNS-ECP 1” 18-22G — 0.875” – 1.025” (2.20 – 2.60 cm)
- TNS-ECP 1 1/8” 18-22G — 1.000” – 1.150” (2.54 – 2.92 cm)

We pride ourselves on getting back to you right away. After you have identified and procured the correct Torq N’ Seal® plugs, you are ready to seal the leaking tubes. Follow the 3 simple steps below to ensure a permanent, positive seal up to 250 psi!
Step 1: Prepare the Tubes and Plugs
Remove any loose scaling or oxide formation by means of a tube brush. Snap the Elastomer Condenser Plug onto the specialized 5/16” Hex Capture Drive, at least one of these installation tools is provided with every purchase, then attach that to your 3/8” Square Drive Torque Wrench. Set the Torque Wrench to 120 in-lbs.
Step 2: Insert the Plug into the Tube
Align the cam with the plug body and insert the plug into one end of the leaking tube. Insert the plug until the screw head is beyond the tubesheet, this will ensure maximum sealing area on the tube Inner Diameter. (Torq N’ Seal® Elastomer Condenser Plugs can be installed well past the tubesheet when necessary. For instance, when there is severe pitting and corrosion at the tube entrance.)
Step 3: Seal the Tube
Begin to rotate the T Handle Hex Capture Drive clockwise. As you rotate, the cam will fall out of center with the plug body and “lock” the plug into place. This provides the necessary anti-rotation force that will allow the screw to compress and expand the EPDM seal, effectively plugging your tube.
Continue rotating clockwise until the Torque Wrench clicks to indicate 120 in-lb has been reached.
Your tubes are now sealed up to 250 psi at up to 350°F.
Step 3a: Removing Plugs
Simply re-insert the Hex Capture Drive and rotate counter-clockwise. This will decompress the EPDM seal and allow the plug to slide easily out of the tube.
