Advanced Sealant Technology
Slime sealant instantly seeks out and repairs punctures up to ¼” without causing damage to the tire or tire pressure sensor system. This highly developed sealant is able to pass directly through the valve core, eliminating the need to remove the core before repairing the tire.
Powerful Reusable Compressor
The built in 12 volt compressor fully inflates any tire in less than 7 minutes allowing drivers to get back on the road more quickly than ever. This reusable compressor is designed to be regularly used to maintain proper tire pressure in any vehicle. It is also great for inflating ATV, bicycle and motorcycle tires and more.
Built-In Safety Features
The system features a built in gauge to easily verify that correct tire pressure has been achieved eliminating the worry that a tire may be dangerously under inflated.
The safety light delivers a bright beam of light to the area around the system making a night repair less dangerous.
