Fix the Leak, Save the AC – The Smart Way.

Has your car’s air conditioning lost its cool? Before you pay for expensive diagnostics or replace costly metal parts, consider this: The #1 cause of AC refrigerant loss is dried-out rubber O-rings and seals.

Over time, the rubber seals in your AC system shrink and crack, allowing gas to escape. Freeze Car Stop Leak (Rubber) is the intelligent, low-cost solution to fix this problem permanently.

How It Works

Unlike messy sealants that can clog your system, FreezeCar Stop Leak uses a specialized conditioning agent. When it circulates through your AC system, it penetrates rubber components (O-rings, gaskets, and hoses), causing them to rehydrate and swell slightly. This restores their original shape and creates a tight, leak-proof seal.

Why Choose Freeze Car Stop Leak?

• Save Hundreds on Repairs: Why pay a mechanic to replace a 50-cent O-ring buried deep in your engine? This can fixes it from the inside out.

• Dual-Action Formula: Not only does it stop leaks, but it also contains high-quality lubricants that reduce compressor noise and extend the life of your system.

• Safe & Compatible: Our formula is non-clogging and contains no polymers that harm recovery machines. It is fully compatible with:

  • Refrigerants: R134a, R12, and R1234yf replacements.

  • Oils: Mineral, PAG, and Ester oils.
