A 12 oz can of R-134a refrigerant with a seal-swelling additive, sold as a refill for B'laster hose kits. The additive is meant to stop small leaks on metal and rubber seals while topping up the charge and oil. It suits drivers of older gasoline cars with a slow leak who want a quick top-up before a proper repair. It is not a fix for a major leak, and it cannot be used on hybrids or EVs, which run different refrigerants and sealed systems.

This is a 12 oz. can of R-134a refrigerant refill for use with B'laster R-134a hose kits. It comes as an aerosol.
The formula replaces refrigerant and oil to improve cooling. It includes Safe Seal, which permanently repairs and prevents leaks on metal and rubber parts. Safe Seal does not damage the AC system or recovery machines, and the formula protects internal parts to extend the life of critical components.
It is not intended for use on hybrid or EV vehicles.
