TireJect Off-Road Tire Sealant Kit 20oz — Permanent Repair for Tread & Sidewall Punctures, Bead & Slow Leaks

TireJect Off-Road 20oz is a ready-to-use tire sealant kit that permanently seals tread and sidewall punctures, bead leaks, slow leaks and minor dry rot for tubeless off-road tires.

When you're out on trails, a sudden puncture doesn't have to end the day. This compact TireJect kit delivers a low-viscosity liquid rubber formula blended with recycled tire particles and aramid fibers that bonds to rubber and stops air loss without the heavy, goopy residue of many gel-type sealants. The kit includes an injection pouch cap, metal valve core remover, and valve stem cap so you can apply the sealant quickly through the valve stem and get back on the trail.

How does TireJect stop a puncture while I’m out riding?

The sealant flows through the valve stem and into the tire as air escapes, carrying rubber particles and fibers that lodge in the puncture to form a flexible, permanent seal. Because it’s thin and low-viscosity, it spreads evenly inside the tire and adheres to the inner rubber surface for a durable repair.

• Seals tread and sidewall punctures up to 3/8"
• Stops bead leaks and slow leaks in tubeless tires
• Thin formula avoids heavy build-up that reduces balance

Will TireJect work on my ATV, UTV or lawn tractor tires?

This formula is designed for tubeless off-road applications — ATV, UTV, SxS, riding mowers, tractors, golf carts and similar equipment. It is not compatible with TPMS sensors; for vehicles with tire pressure monitoring systems choose TireJect Auto instead.

• Suitable for most tubeless off-road tire sizes and bead types
• Not for inner-tube tires or TPMS-equipped wheels
• Works on common small equipment: wheelbarrows, carts, mowers

How easy is it to apply this kit in the field?

The kit is built for simplicity: remove the valve core with the included metal tool, attach the pouch cap and squeeze the sealant in through the valve stem. Many users can perform the repair without removing the wheel, then ride slowly to let the sealant spread and cure.

• Includes pouch cap, valve-core remover and valve stem cap
• Requires no special pumps or tools beyond what's supplied
• One 20oz bottle treats multiple tires; typical usage is lower per tire

How long does the repair last and what does the formula contain?

TireJect’s sealant combines liquid rubber, recycled tire particles and aramid fibers to create a flexible plug that bonds to the tire interior. It’s formulated to provide a permanent repair for eligible punctures and to resist slinging or clumping common with thicker gels.

• Liquid rubber base for strong adhesion to rubber surfaces
• Recycled tire particles and aramid fibers provide structural fill
• Low viscosity minimizes weight and balance issues

Who is this for? If you ride or work off-road and need a compact, reliable way to prevent and repair flats on tubeless tires, TireJect Off-Road 20oz is made for you. It’s ideal for ATV/UTV owners, landscapers, farmers, golf course crews, and trail riders who want a permanent, low-residue sealant that’s easy to apply in the field. Manufactured and supported in the USA by a family-owned company, the kit provides the core tools to inject sealant quickly and get back to work or play.
