TireJect™ Technology is the key
Our patent pending Tire Repair Sealant is a proprietary blend of thinner, faster flowing sealant paired with the strength of Dupont™ Kevlar® fiber - the fiber that's stronger than steel. TireJect Tire Sealant plugs the tire from the inside and adheres the Kevlar® Fiber into the puncture or leak forming a permanent plug from the inside. Competing tire sealants do not form a permanent plug. TireJect is water soluble, easier to work with and provides superior flat repair and prevention.
Puncture demos
Make your tire, literally, bulletproof
Do not attempt this at home! TireJect is the most effective tire sealant on the market - we have made all sorts of puncture demo videos, but this shows it all! Seal any leaks, punctures and even bullet holes!
Driving over a bed of nails
If you see us at a riding event, we are still riding on this tire. We 100% trust our tire sealant and it permanently seals any air leaks from punctures up to 3/8" in the tread or sidewall and even seals bead leaks or dry rot.
TireJect™ vs Slime tire sealant
Anyone that has used a traditional tire sealant like Slime tire sealant knows that it is an absolute mess to work with and commonly does not work. Slime is thick, goopy and designed to stick to your tire and rim. The thick formulation of Slime is designed to stick to the tread area for limited protection of your tires and it causes tire balance issues.

So far, so good.

It's only been a couple of weeks, but this product has been excellent to date. Very easy to use. My tire is still holding air. Haven't had to add any air since installing this product.
