R-454B Refrigerant – 25 lb Factory-Sealed Cylinder

R-454B is an AHRI-700 certified, virgin A2L refrigerant developed as a lower-GWP alternative to R-410A for new-generation A/C and heat-pump equipment. With a GWP of approximately 466, it delivers strong cooling and heating performance for systems built to run on it.

What You Get

• 25 lb factory-sealed cylinder, 100% virgin refrigerant
• AHRI-700 certified purity
• A2L – mildly flammable classification
• GWP of approximately 466
• Strong cooling and heating efficiency

Best for: new residential A/C systems, commercial HVAC equipment, and heat pumps specifically designed for R-454B.

Please note: R-454B is an A2L refrigerant and requires compatible equipment, correct installation and ventilation, and appropriate safety practices.

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-454B is a lower-GWP successor to R-410A, but it's not a drop-in – it requires equipment specifically engineered and approved for R-454B.
• What does the A2L safety classification mean?
  It's a refrigerant industry safety rating. This product is classified A2L (mildly 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 and open flame, given its flammability classification.
