Monkey Grip introduces new innovative packaging of their EZ Seal Tire Sealant. This boxed kit includes 4 cartridges of the EZ Seal Flat Prevention Sealant along with the EZ Fill installation gun. Each cartridge contains the proper amount of EZ Seal required to seal up to a 1/4" puncture in most standard passenger car tires. Unlike aerosol flat fixers, EZ Seal is designed as a preventative product to extend tire life and performance. EZ Seal is ideal for application with new tires as well as older, more worn ones and the product's unique chemical compound is activated if a puncture or slow leak occurs. The molecular structure of EZ Seal establishes a synthetic "patch" at the point of puncture or leak.
