TireJect Lawn Mower Tire Sealant Kit — 30 oz Injector Repair & 2-Year Flat Protection for Small Mower Tires

Designed for lawn tractors, zero-turns, riding mowers and utility trailers, this kit supplies a durable, fiber-reinforced sealant and a simple injector tool so you can stop leaks through the valve stem without removing the tire. The formula blends liquid rubber, recycled tire particles and aramid fibers to form a long-lasting plug that works on both tread and sidewall damage and can be pre-applied to prevent flats for up to two years.

How does this kit fix a punctured lawn mower tire?

Inject the TireJect sealant through the valve stem after removing the valve core with the included tool. The sealant flows to the puncture, combining rubber and fibers to fill the hole and create a flexible, durable patch while air pressure seats the mixture into the damage.

• Fixes punctures up to 3/8" diameter in tread and sidewall
• Stops bead leaks between tire and rim
• Works without tire removal in most cases
• Includes valve-core removal tool and sealant injector

Can I prevent future flats by pre-treating my tires?

Yes — you can pour the recommended amount into each tire to create ongoing protection against nails, thorns, screws and minor dry rot. When installed proactively, TireJect helps maintain tire pressure and reduce the chance of a roadside flat for up to two years, depending on conditions.

• Pre-apply to all four tires for continuous protection
• Coverage: most rear mower tires up to 24x12 and front tires up to 16x7
• Reduces downtime from unexpected punctures
• No special skills required for installation

What is included and how do I use the injector tool?

The kit comes with a 30 oz bottle of TireJect sealant, a sealant injector for valve-stem application, a valve-core removal tool, red valve caps, and a protective TireJect sticker. Remove the valve core, attach the injector, deposit the correct amount of sealant, reinstall the valve core, then run the tire briefly to distribute the product.

• 30 oz sealant bottle engineered for small tires
• Sealant injector fits standard valve stems for easy dosing
• Valve-core tool and caps included for a complete installation
• Simple instructions—no dismounting usually required
