RS-44B (R-453A) Refrigerant – 25 lb Factory-Sealed Cylinder

RS-44B is an AHRI-700 compliant, non-flammable (A1) virgin refrigerant built as a high-performance alternative to R-22 across a wide range of existing air-conditioning and refrigeration systems. Supplied in a brand-new 25 lb cylinder, it carries a lower GWP than many common R-22 retrofit refrigerants while keeping the conversion process simple.

Key Benefits

• AHRI-700 compliant: high-purity virgin refrigerant for dependable, repeatable performance.
• Lower-GWP R-22 alternative: GWP of approximately 1,664, lower than several widely used R-22 replacements.
• No routine oil change: compatible with mineral oil, alkylbenzene, and POE lubricants.
• Straightforward R-22 retrofit: suited to many existing systems without major hardware changes, when approved for the specific equipment.
• A1 safety classification: non-flammable and lower toxicity, supporting safe handling.
• Broad application range: residential and commercial A/C, split systems, chillers, and commercial refrigeration.

Quick Specifications

• Low-temperature range: applications down to roughly -20°F evaporating temperature, where approved
• Condition: brand-new, factory-sealed cylinder

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?
  RS-44B is designed for many existing R-22 systems without major hardware changes, but approval for the specific equipment should be confirmed first.
• 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.
