Imagine driving on a construction site, cycling through a rocky trail, or navigating icy roads. A sudden puncture could ruin your plans, delay operations, or even put you in danger. Enter tyre sealants: an innovative solution designed to keep you moving without interruption. But how does tyre sealant work? Here, we break it down for you, step by step
What is tyre sealant?
Tyre sealant is a liquid solution that is applied inside a tyre to prevent and repair punctures. Once inside the tyre, it actively seals holes caused by nails, sharp rocks, or other debris. 11D Tyre Sealant goes a step further: it’s eco-friendly, reliable, and designed for extreme conditions.
Choosing the right tyre sealant is important for preventing punctures and extending tyre life. Every tyre requires a different amount of sealant.
Choose the right amount you need. Our Calculator can help you to choose the correct amount.
How does tyre sealant work?
The magic of tyre sealants lies in their composition. Here’s a simple explanation of what happens:
- Application: The sealant is injected into the tyre through the valve stem using a specialized injector or nozzle.
- Distribution: As the tyre rotates, centrifugal force spreads the sealant evenly along the inner surface.
- Reaction to Punctures: When the tyre is punctured, air escapes and pushes the sealant towards the hole.
- Sealing: The sealant fills the puncture, and its fibres create a durable plug. For 11D Tyre Sealant, this process can seal holes up to 24 mm (depending on the tyresize) instantly, keeping the tyre fully operational.
This proactive approach means punctures are fixed before they become a problem, saving you time, money, and hassle.
