R-427A Refrigerant – 25 lb Factory-Sealed Cylinder

R-427A is an AHRI-700 certified, virgin A1 refrigerant developed as a lower-GWP alternative to R-22 for air-conditioning, heat-pump, and refrigeration systems. Its broad oil compatibility and R-22-like operating characteristics make it a versatile retrofit option.

What You Get

• 25 lb factory-sealed cylinder, 100% virgin refrigerant
• AHRI-700 certified purity
• A1 – non-flammable classification
• Works with POE oils and residual MO/AB oil
• Reliable performance and cooling capacity

Best for: residential and commercial A/C, heat pumps, and low- to medium-temperature refrigeration.

Please note: confirm system compatibility and follow the manufacturer's specifications and applicable regulations before retrofitting.

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-427A offers broad oil compatibility for R-22 retrofits, but a system compatibility check is still recommended before conversion.
• 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 cylinder upright in a cool, dry, well-ventilated area out of direct sunlight, and keep it away from heat sources.
