Please note: R-22 is an ozone-depleting substance and its use is restricted in many markets. Confirm it's legal for your application before purchasing, and use only in existing equipment already designed for R-22. Leak-stop is intended for minor leaks, not as a substitute for a proper repair.

Why Purity & Certification Matter

Refrigerant purity has a direct effect on system performance and equipment life. Non-condensable gases, moisture, or residue in a charge can raise head pressure, reduce cooling capacity, and shorten compressor life. Buying a factory-sealed, virgin charge – rather than reclaimed or repackaged product of unknown origin – is the simplest way to protect the equipment you're servicing.

Frequently Asked Questions

Is this a drop-in replacement for another refrigerant?
R-22 is only for topping off existing R-22 systems – it's not intended for new installations, which no longer use R-22.
What does the A1 safety classification mean?
It's a refrigerant industry safety rating. This product is classified A1 (non-flammable), which describes its flammability under ASHRAE/ISO guidelines and determines what handling and installation precautions apply.
Can this be shipped, and how should it be stored?
Refrigerants are regulated hazardous materials and generally ship via ground freight under DOT rules. Store the can upright in a cool, dry, well-ventilated area out of direct sunlight, and keep it away from heat sources.
