About this item
Product details
FlatOut QuickStrike Small Tire/Bicycle Formula Tire Sealant is a one-time tire sealant designed to help prevent flat tires and deliver reliable flat tire repair performance for the life of the tire. This advanced bicycle tire sealant helps seal punctures up to 1/4 inch and virtually eliminates slow leaks caused by valve stems, beads, and natural tire porosity. Made with synthetic TangleTek fibers including Kevlar and proprietary DamRight fillers suspended in our special Never-Settle base fluid, FlatOut creates a powerful air-tight fiber seal when punctures occur. Escaping air forces the formula into the damaged area, forming a durable plug that quickly seals the opening. Unlike messy adhesive-based formulas, this bike sealant is water-washable, latex-free, freeze-resistant, and will not dry out inside your tires. Designed for both tubed and tubeless tire sealant applications, FlatOut provides dependable performance for bicycles and small tire equipment. Proven in demanding military and industrial environments for decades, FlatOut delivers dependable puncture protection and long-lasting performance.
- Fast QuickStrike Formula: NEW FlatOut QuickStrike Small Tire/Bicycle Formula flows faster into punctures when there is no air to spare, providing quicker sealing performance and easier installation.
- Lifetime Tire Protection: FlatOut QuickStrike Tire Sealant is a one-time application that works for the life of the tire, seals tread-area punctures up to 1/4 inch, and helps prevent flat tires by reducing slow leaks.
- Works with Tubed & Tubeless Tires: High-performance tubeless tire sealant designed for both tubed and tubeless tire applications for reliable puncture protection.
- Advanced Kevlar Fiber Technology: Made with super-strong Kevlar fibers, this bike sealant is water-washable, latex-free, adhesive-free, and will not dry out or create sticky residue.
- Prevents & Repairs Punctures: FlatOut QuickStrike tire sealant helps repair punctures, seal leaks, and provide dependable flat tire repair performance for small tires and bicycles.
- Designed for Small Tires & Bicycles: Ideal bicycle tire sealant for bikes (tires under 3.5" wide), mobility scooters, mopeds, One Wheels, scooters, and similar equipment. Not recommended for passenger vehicles.

Riding Without Fear of Flats
The plastic Schrader valve tool included in this product can break and the pieces are hard to remove. The product itself successfully seals and leaks in the tubes. I haven't had any flats since I installed it.

This stuff is so much better than the green slime. And much easier. Remove the valve course stem squirted in 6 to 8 ounces replace the valve stem air it up and go. Simple fix a flat and just a couple of minutes compared to the old bike patches when we were kids lol. I love this stuff. I have already recommended it to many people. Flat out is where it's at
