FlatOut QuickStrike Tyre Sealant 1 Gallon + Tool — Off-Road, Kevlar‑Reinforced Fast‑Flow

FlatOut QuickStrike Tire Sealant is a kevlar-reinforced, long-lasting sealant designed to prevent and repair tread-area punctures up to ½" in tubed or tubeless tires.

FlatOut QuickStrike pairs a fast-flowing formula with Kevlar fibers so the product reaches punctures quickly, seals them, and stays flexible without sticky residue. This one-gallon kit includes a dispensing tool and is formulated for heavy-duty and off-road applications such as RVs, trailers, and utility vehicles. It’s latex- and adhesive-free, water-washable, non-flammable and non-corrosive, making it practical for ongoing protection and repair on the go.

How quickly does QuickStrike stop a leak when a puncture happens?

The QuickStrike formula is engineered to flow rapidly toward the source of air loss so fibers and sealant arrive at a puncture faster than standard products. In many cases it seals slow leaks almost immediately and larger tread-area punctures up to ½" within minutes of contact.

• Fast-flowing liquid for rapid reach into punctures
• Kevlar fibers lock into the hole to form a durable patch
• Works while tire still has minimal air pressure
• Seals both slow leaks and sudden tread punctures

Will this sealant make a mess inside my tire or damage components?

FlatOut QuickStrike is designed to remain non-sticky and water-washable, avoiding the gooey residues common with older sealants. Because it’s latex- and adhesive-free, it won’t gum up valve stems or bead areas and is compatible with both tubed and tubeless tire setups when used as directed.

• Latex- and adhesive-free to prevent stickiness
• Water-washable for easier cleanup during servicing
• Non-corrosive so it won’t attack rims or valves
• Includes installation tool for clean, controlled dispensing

How long does protection last after application?

QuickStrike is formulated as a one-time, long-lasting treatment for the life of the tire when applied correctly. The Kevlar fibers and stable carrier fluid remain active over time to address future punctures and minimize slow leaks, so frequent reapplication is generally unnecessary.

• One-time application intended to protect for tire lifetime
• Stable, non-drying formula maintains sealing ability
• Reduces need for repeated top-ups under normal use
• Recommended for heavy-duty and trailer applications rather than passenger cars

Is QuickStrike suitable for my vehicle type and how do I use it?

QuickStrike On Road Formula is tailored for RVs, boat trailers, horse trailers, utility trailers and similar heavy or seasonal vehicles. It is not recommended for standard passenger cars. Installation is straightforward using the included tool: remove the valve core, attach the dispenser, inject the measured quantity based on tire size, reinstall the valve core and rotate the tire to distribute.

• Best for RVs, trailers, and off-road/heavy-duty tires
• Not recommended for everyday passenger cars
• Includes tool and clear instructions for controlled dosing
• Works in both tubed and tubeless tires when applied correctly

Who is this for? FlatOut QuickStrike is aimed at owners of RVs, trailer fleets, off-road rigs and utility vehicles who need reliable, low-maintenance puncture protection and emergency repair. If you haul gear, travel long distances with trailers, or operate in environments where tread punctures are common, this kevlar-enhanced, water-washable sealant delivers fast action and lasting coverage without sticky cleanup.
