How to use
Valve Position:
Typically, valves are positioned at either 4 o'clock or 8 o'clock when viewed from the front. This means they'll be at the lower part of the tire.
1
Removing the Valve Core:
Insert the special tool into the valve and turn it counter clockwise to unscrew the valve core. This allows the sealant to be injected into the tire easily.
2
Inject the Sealant:
Squeeze or pour the sealant into the valve stem.
Inject the Recommended Amount:
Refer to the instructions on the sealant packaging for the recommended amount to inject based on your tire size.
3
Reinstall the Valve Core:
Using the valve core removal tool in reverse, screw the valve core back into place securely. This prevents air from escaping and keeps the sealant inside the tire.
4
Inflate the Tire:
After reinstalling the valve core, inflate the tire to the recommended pressure level as specified by the manufacturer.

How it works:
Tire sealant works based on a combination of physical and chemical principles. Here’s a scientific breakdown of how it works:
1- Composition
Most tire sealants are made from:
-
Carrier fluid (usually water- or glycol-based)
-
Suspended solids (like rubber particles, fibers, or other fillers)
-
Latex or polymer base (to help coagulate and form a seal)
-
Additives (to prevent corrosion, mold, freezing, etc.)
2- Centrifugal Action
When the wheel spins, centrifugal force distributes the sealant evenly along the inside of the tire tread. This coating enables it to be ready in the event of a puncture.
3- Puncture Sealing (Mechanical + Chemical Reaction)
When a puncture happens:
-
Air pressure inside the tire forces the sealant into the hole.
-
The suspended fibers and particles get trapped in the puncture path.
-
The latex or polymer in the sealant begins to coagulate (clot) as it comes into contact with outside air and moisture.
-
This forms a plug or scab that seals the hole, often instantly.
4- Self-Healing Properties
Some advanced sealants stay active and flexible for long periods. If the seal breaks (due to further movement or pressure), the sealant can re-seal the same hole or others, as long as there’s enough product left inside the tire.
5- Pressure-Driven Seal
The internal air pressure is key; it pushes the sealant into the puncture, aiding in faster and stronger sealing. The higher the pressure, the faster the response.
