Titanium Tube Plugs

Our titanium tube plugs are made with a titanium nut and bolt assembly. We manufacture the collar and washers from a non-water soluble hard plastic called Hytrel and the silicone parts are comprised of a vulcanized silicone rubber.

The quality tube plugs Heat Exchanger Products Corporation offers come in either a double size (two silicone parts) or a single size (one silicone part). The single plugs are recommended for lower pressures and the doubles are for pressures up to 200 psi*. Install our titanium tube plugs with a Pre-Set Torque Wrench Installation Kit from HEPCO that will take any guesswork out of the installation process.

*7/8″-1 1/4″ sizes up to 200 psi – 5/8″-3/4″ doubles up to 150 psi prolonged use.

Key Benefits:

-Will not fracture / distort tube or tube sheet


-Easily installed / extracted


-Ideal for coated surfaces
