  • lose to twice the amount of sealing crystals plus special “XL” crystals capable of sealing even larger punctures.
  • Combination of large and small sealing crystals interlock to form a lattice work that not only seals but strengthens and reinforces the area of the puncture allowing for an entirely new level of sealing performance
  • Must be installed directly into the tire – cannot be injected through the valve
