If you've walked the mechanics' pits at any National or International level event, chances are you've seen a bottle of Stan's No Tubes. Stan's has developed a proprietary sealant formula with close to twice the amount of our standard sealing crystals plus our special "XL" crystals capable of sealing even larger punctures. This combination of large and smaller 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.

Note: The quantity and size of crystals in this special formula means that Stan's Race Sealant can only be installed directly into the tire. As a result of its immense sealing capabilities, the Race Sealant will clog injectors and smaller bottles almost immediately.
