FlatOut Off-Road Multi-Purpose Tire Sealant is a Kevlar-reinforced, tubeless tire liquid that both prevents and repairs punctures across ATVs, UTVs, lawn equipment, trailers and off-road vehicles.

Keep tires rolling with a ready-to-use sealant designed for rugged conditions. FlatOut combines strong Kevlar fibers with a water-washable, non-toxic carrier to stop slow leaks and seal tread punctures up to roughly 1/2 inch. Supplied in a 32-ounce bag with an easy-install cap, this formula is meant for both proactive protection and on-the-spot repair for a wide variety of tubeless tires.

How quickly does this sealant stop a puncture?

FlatOut works rapidly once it reaches a breach in the tread area. Centrifugal action from wheel rotation spreads the liquid across the damage site, where fibers and the base fluid form a durable plug in seconds to minutes depending on hole size and wheel speed.

  • Seals most tread punctures up to 1/2 inch in size.
  • Begins forming a plug immediately as air escapes and the wheel spins.
  • Effective for both sudden flats and slow leaks when applied preventatively.

Will this work with my vehicle or equipment?

The formula is designed for wide compatibility with tubeless tires across many sectors. Use it in off-road Jeeps, ATVs, UTVs, dirt bikes, golf carts, riding mowers, boat trailers and selected industrial equipment — virtually any tubeless tire where a liquid sealant is appropriate.

  • Safe for typical off-road wheel and tire materials when used as directed.
  • Not intended for inner tubes or non-tubeless systems unless specifically recommended.
  • Commonly used by landscapers, construction crews and recreational riders.

How do I apply the 32-ounce FlatOut sealant?

Application is straightforward: shake the pouch, remove the valve core, inject the recommended volume through the valve stem, reinstall the core and re-inflate. The included easy-install cap speeds the process and helps avoid spills.

  • Shake pouch thoroughly before use to disperse Kevlar fibers evenly.
  • Inject through the valve stem after removing the valve core; follow tire manufacturer dosing guidelines.
  • Reinflate and rotate the wheel to distribute sealant evenly across the tread area.

Does the product leave a mess or damage wheels?

FlatOut is formulated to be non-toxic, water-washable and free of latex and adhesives, minimizing sticky residue and rim buildup. Kevlar fibers provide reinforcement without creating a hard, abrasive deposit, and routine tire maintenance and washing will remove residual fluid safely.

  • Water-washable formula cleans off rims and tires more easily than adhesive-based sealants.
  • Latex- and adhesive-free to reduce gumming and long-term buildup inside the tire.
  • Designed to avoid corrosive or damaging components for common wheel finishes.

Who is this for: FlatOut Off-Road Sealant suits professionals and weekend adventurers who need dependable, low-maintenance puncture protection. It’s a practical choice for landscapers, construction operators, fleet managers, off-road enthusiasts and homeowners with riding equipment who want proactive leak prevention and quick field repairs without the mess of traditional latex products.

FAQ

Q: Can I use this sealant in inner tubes?

A: No. FlatOut is formulated for tubeless tires and should not be used in inner tubes unless the tube maker specifically approves liquid sealants.

Q: How long does protection last after application?

A: When used preventatively, the formula can prevent slow leaks for years; check and replenish per riding conditions and manufacturer guidance.
