Brief Introduction


Visbella® radiator stop leak is a non-toxic, high-performance compound engineered to fix leaks in automotive, commercial, and agricultural cooling systems. This innovative cooling system leak sealer quickly mixes with antifreeze, flowing through radiators, heater cores, and freeze plugs to form a permanent seal—without clogging hoses, water pumps, or delicate components. Crafted with a safe, biodegradable formula, it’s compatible with all types of antifreeze (ethylene glycol, propylene glycol) and protects against rust, corrosion, and wear.

Core Features


Non-Toxic & Eco-Friendly Formula

The non-toxic stop leak is free of harmful chemicals, making it safe for humans, pets, and the environment. It’s biodegradable and won’t contaminate soil or water sources.


Fast-Acting Leak Sealing

Designed for rapid leak repair, the powder mixes instantly with coolant, flowing to leak points and forming a permanent seal within 15 minutes of engine operation. No waiting for hours—get back to use quickly.


100% Antifreeze Compatible

Compatible with all types of antifreeze and coolants, the antifreeze-compatible sealer won’t react with existing fluids or damage cooling system components. It’s safe for both old and new vehicles.


Clog-Free Cooling System Protection

The ultra-fine powder particles seal only leaks, not coolant passages. This clog-free stop leak ensures optimal coolant flow, preventing overheating and damage to water pumps or radiators.


Rust Inhibition & Component Lubrication

Beyond sealing leaks, the formula acts as a rust inhibitor and water pump lubricant, reducing friction and wear on internal components. This extends the lifespan of radiators, water pumps, and hoses.


Versatile Vehicle Compatibility

Works with all vehicles—cars, trucks, vans, buses, tractors, and agricultural machinery. The multi-vehicle stop leak adapts to different cooling system sizes and configurations.


Permanent Leak Repair

Forms a chemical bond with metal and plastic components, creating a permanent leak seal that withstands temperature changes, pressure, and vibration. No need for repeated applications.
