The ultra-stable, low-glide replacement for R-22. Our 25 lb RS-44B (R-453A) Virgin Cylinder provides a seamless, cost-effective retrofit path for residential air conditioning, commercial HVAC systems, and low-to-medium temperature refrigeration units without requiring an expensive system tear-out.
Engineered with the lowest temperature glide of any major R-22 drop-in alternative, RS-44B provides highly consistent cooling performance and prevents the common expansion valve hunting associated with older retrofits. Every tank arrives factory-sealed and laboratory-certified to strict AHRI-700 standards, ensuring 100% virgin chemical integrity right out of the box.
Key Benefits of RS-44B (R-453A):
-
No Oil Changes Required: Fully compatible with traditional Mineral Oil (MO), Alkylbenzene (AB), and modern Polyolester (POE) lubricants. You can skip the tedious process of oil flushing and keep the existing lubricant in the system.
-
Industry-Lowest Temperature Glide: Minimizes pressure fluctuations and ensures highly uniform temperatures across the evaporator coil, closely mimicking original R-22 performance.
-
Direct Component Match: Replicates R-22 mass flow and operating pressures, meaning it works beautifully with your existing thermal expansion valves (TXVs), cap tubes, and capillary line configurations.
-
ASHRAE A1 Safety Rating: Certified non-flammable and non-toxic, allowing for standard handling, storage, and transport protocols on service vehicles.
-
AHRI-700 Certified Purity: 100% virgin composition eliminates moisture and non-condensable risks, safeguarding the compressor from premature internal failure and acid burnouts.
