PTFE Tech-Patch for repairing gas tanks.


SKU: N/A Category:


PTFE Tech-Patches for repairing metal or plastic gas tanks.

PTFE patches have a Teflon (PTFE) strip bonded onto one side.  PTFE has excellent resistance to gasoline and diesel fuels, even aromatic (high octane) formulations.  You will bond the PTFE side of the patch onto the damaged gas tank.  With the PTFE patch, any hole and crack in either plastic or metal gas tanks will be permanently sealed.

Choose the correct Tech-Bond Kit for the type of gas tank that you need to fix.

For plastic gas (poly) tanks/containers

Poly Kits

Choose an Economy Poly (Coverage – approx: 30 sq in) Kit, a Poly (Coverage – approx: 100 sq in) Kit or a Poly Plus (Coverage – approx: 100 sq in) Kit for repairing plastic (poly) gas tanks or containers.  Our patented Polymer Bonding Process will allow you to repair these otherwise unrepairable items.

For metal gas tanks/containers

Starter Kit

Choose an Economy (Coverage – approx: 30 sq in), Starter (Coverage – approx: 100 sq in) or Starter Plus (Coverage – approx: 200 sq in) Kit.

Note:  For a bond to form between a PTFE Tech-Patch and any metal substrate, pipe or tank, the metal surface must be abraded to either a “polished surface” or, with steel, a “near white” surface.  Anything less in surface preparation will, over time; result in bond failure.

Making your Tech-Patch “Plus”.

In situations when extra protection against abrasion is needed, apply several coatings of our SI adhesive to the outside of your Tech-Patch.  Examples of when you need to have a coating might include:

  • Where the Tech-Patch will be subjected to unusual stress.
  • If there is a strap holding the gas tank to the undercarriage.
  • If your repairing a larger hole, the coatings will resttict the expansion of the patch.

If you want to “Plus” your Tech-Patch, make sure you have enough of the SI adhesive.  Step-by-step instructions for plussing your patch are included.

Both the Polymer Bonding Process and Tech-Patches are new technologies.  But our reviews confirm that both technologies are very effective.  Simply put, they always work.  Once your a customer, we would appreciate if you would leave a Google review.  Link below. Thank you.

Working with polyurethane, we developed the Polymer Bonding Process (Process) for bonding polymers in November of 2016.  Recognition of the value in being able to bond polymers was immediate.  So was the skepticism.  Would the bond last?  What polymers does the Process work on?  Does the Process work to bond polymers to other materials?

In the years since, we answered every question in the affirmative.  With the Process you can bond any polymer to itself, to any other polymer and to almost any other substrate.  As important fact is that bonds created by the Process are permanent.   Everyone who has tried has had success in bonding polymers or fixing their broken plastic piece.  Everyone!  That is why we have not refunded a dime under our money back guarantee.

Fluorosilicone (FVMQ) has excellent resistance to standard fuels, but high octanes gasolines can impact fluorosilicone.  In addition to being impervious to standard fuels, PTFE (Teflon) has excellent resistance to the additives, benzene, xylene, etc., that increase octane rating.   For the PTFE patches, we developed a process that bonded Teflon tape to the fluorosilicone.  The Process does a superb job of bonding the PTFE to HDPE (plastic) tanks.  Almost the same core chemistry bonds the patches to metal gas tanks.

Note: We developed PTFE Tech-Patches for repairing gas tanks and they do a wonderful job.  PTFE patches will also have a very high stress rating.  We expect the psi to be exceed 240, so PTFE will be the patch of choice for large volume tanks.  Stay tuned for the test results.
