FlatOut QuickStrike Off-Road Tire Sealant, 32 oz Bag — Kevlar Reinforced, Water-Washable

FlatOut QuickStrike Off-Road Tire Sealant is a fast-acting, Kevlar-reinforced tire sealant in a 32-ounce bag designed to prevent and repair punctures and slow leaks in off-road tires for the life of the tire.

FlatOut QuickStrike Off-Road Formula is engineered to flow quickly into punctures, form durable plugs, and keep tires serviceable without messy adhesives. The water-washable, latex-free formula contains Kevlar fibers that help seal holes up to 1/2 inch and is formulated for a wide range of off-road and heavy-duty soft-surface applications. It works in both tubed and tubeless setups and is non-flammable and non-corrosive, giving you a practical, long-term alternative to frequent patching or roadside repairs.

How fast does QuickStrike seal a puncture when you're off-road?

The QuickStrike formula is optimized to reach punctures quickly so that air loss is minimized while you're riding or working. It is intended to act immediately on tread-area holes and slow leaks, letting you continue without an urgent wheel change.

• Flows rapidly to the puncture for quick sealing action.
• Seals tread-area punctures up to 1/2" when applied correctly.
• Reduces the frequency of roadside repairs and air top-ups.

Will this sealant work in both tubed and tubeless tires?

Yes — FlatOut QuickStrike is formulated for compatibility with both tubed and tubeless tire assemblies. Because it is latex- and adhesive-free, it won’t create a sticky residue inside the tire or tube and remains water-washable for easier cleanup.

• Suitable for tubed and tubeless configurations used on off-road vehicles.
• Water-washable for straightforward removal if needed.
• No latex or tacky adhesives to gum up rims or bead areas.

What kinds of punctures and slow leaks can QuickStrike handle?

The Off-Road Formula targets typical off-road damage: nails, thorns, and small tears in the tread area. Its Kevlar fiber content helps form a reliable plug for holes up to 1/2 inch; it also significantly reduces slow leaks so tires hold pressure longer between refills.

• Designed for tread-area punctures up to 1/2" diameter.
• Effectively minimizes slow leaks and pressure loss over time.
• Contains durable Kevlar fibers for stronger, longer-lasting plugs.

How long does one application last and is maintenance required?

FlatOut QuickStrike is formulated as a one-time application intended to protect for the usable life of the tire when installed per directions. Routine visual checks and pressure monitoring are still recommended, but you should expect far fewer reseals or emergency repairs compared with untreated tires.

• One application designed to last the tire’s lifetime under normal use.
• Reduces need for repeated sealant top-ups or emergency fixes.
• Periodic pressure checks and inspections are still advised.

Who is this for: FlatOut QuickStrike Off-Road Formula is aimed at riders and operators who spend time on mixed-terrain or soft-surface environments — ATVs, UTVs, dirt bikes, fat-tire bicycles and eBikes (tires wider than 3.5"), golf carts, lawn equipment, and zero-turn mowers. It is not recommended for passenger cars. If you want quick-flowing, Kevlar-reinforced protection that avoids sticky residues and reduces downtime from punctures and slow leaks, this off-road sealant is designed for you.
