This product is versatile, handling slow leaks, bead leaks, and even minor dry rot, which helps extend tire life and can save you money on repairs or replacements.

The sealant uses a combination of liquid rubber, recycled tire particles, and Aramid fibers, which offers a durable and long-lasting seal.

The product is designed for tough off-road conditions, implying good durability in various environments.

It is compatible with a wide range of tire types seen in off-road and heavy-duty vehicles. However, it’s best suited for puncture sizes up to 3/8 inch; larger damages would require professional repair or tire replacement.
