FlatOut QuickStrike Tire Sealant - Off-Road Formula with Kevlar | 1 Gallon + Tool

Fast, reliable puncture protection for rugged tires

FlatOut QuickStrike Tire Sealant delivers a rapid sealing action designed for off-road adventures. The formula travels to puncture sites swiftly, sealing holes in the tread area (up to 1/2 inch) to help you press on with confidence when air is limited. You’ll notice a smooth flow as you apply it, and you’ll experience the peace of mind that comes with knowing a sealant is ready to respond when you encounter unexpected cuts, nails, or thorns on your trail.

One application, long-lasting defense

Designed to endure for the tire’s life, this sealant minimizes the need for roadside repairs by proactively guarding against slow leaks. The formula is reinforced with tough Kevlar fibers, delivering durable sealing power even under demanding conditions. The result is a sealant that stays flexible and effective across temperature swings and rugged terrain.

• Works with tubed and tubeless tires, widening compatibility for mixed setups
• Seals punctures quickly, focusing on tread-area holes for fast return to grip
• Non-flammable and non-corrosive, helping protect wheel components over time

Simple installation you can do on the go

Setup is straightforward: position the valve stem, extend the hose, remove the valve core, inject the sealant, and reinflate. The improved formula and the included valve core tool streamline the process, reducing downtime and making preventive maintenance easier than ever.

• 24/7 protection against punctures and slow leaks, for peace of mind on long trips
• Water-washable and latex/adhesive-free, so cleaning is quick and simple
• Ideal for ATVs, UTVs, golf carts, dirt bikes, fat-tire bikes, and other wide tires (over 3.5 inches)
