We tested Stop Punctures; the anti-puncture preventive liquid

At the beginning of the month we told you about a preventive anti-puncture liquid called Puncture Stop. And the time has come to offer you the results of our experiences with this product. Of course, as it is already a house brand do not wait for a test of use, since we have subjected this Stop Puncture preventive fluid to a particular test, to see to what extent it is capable of repairing a puncture in our tire by itself.

Let's give a review if you have not already done so in the previous post on how to act of this liquid that does not dry inside the wheel, maintaining its effectiveness throughout its useful life so it does not require repair additional after the puncture. In this case we have tested the Puncture Stop for wheels with tube and as you can see its application is very simple.

In the product's own container, which is perfectly graduated on one of its sides to know how much quantity to use, we have everything necessary to introduce the Stop punctures in our tire. A transparent cannula, a small wrench removes the valve shell and in a few minutes once we remove all the air, we will be pressing the container so that the anti-puncture preventive liquid enters.

Depending on the position in which you perform this operation you may notice that sometimes it seems that the liquid gets stuckSimply by loosening the pressure or moving the wheel a little, we will resume the operation.

Once introduced, we clean the valve before putting the core back in, give it pressure and roll with the wheel about 5 kilometers so that the product is distributed throughout the chamber, in our case. They tell us that Puncture Stop prevents and repairs punctures of up to 6.8 mm, so to begin our particular test we start directly with drill the cover with a 5mm drill bit.

As soon as we removed the bit, air began to come out and almost immediately a liquid that with the passage of air was creating a whitish foam, to stop suddenly and as if it were a miracle, stop listening to the noise of the air coming out of the hole. Once the hole is plugged, we check the pressure again and put the grams that had been lost with the puncture, but we are going for more.

As you can see in the cover photo this sample of screws ranging from 3mm to 8mm ended up as it could not be otherwise “screwed” into the tire as if it were “Hellraiser's head”. It already surprised us from the beginning, that nor with the biggest once tight no air left, not even through its thread.

As expected, when removing the first three screws after the initial air leak, the Puncture Stop immediately began to act and plug the hole. Once the wheel is reloaded with the correct pressure since we had lost most of the air with all those punctures, the time has come for the 8mm diameter screw. As soon as the air began to loosen, it was already escaping rapidly and the product could not block the air outlet.

But we decided to give it a second chance and we inflate the wheel again and surprisingly when the pressure was recovered and the air came out again with force together with the Stop Puncture liquid, it plugged the 8mm hole. So we can conclude that the product works, in addition to a price of about 15 Euros per wheel. I am sure that even on wheels with pressures greater than the low kilo of Enduro that we use for this test, it will do so with greater speed and efficiency.
