The definitive no-oil-change replacement for R-22 air conditioning systems. Our 25 lb Freon™ NU-22B™ (R-422B) Virgin Cylinder provides a seamless, cost-effective retrofit path for residential and commercial AC units, helping you keep existing equipment running smoothly without expensive component overhauls.
Engineered to closely mimic the operating pressures and characteristics of R-22, NU-22B keeps system capacity losses to an absolute minimum (typically under 10%) while lowering compressor discharge temperatures. Every tank arrives factory-sealed to guarantee 100% AHRI-700 certified virgin purity right out of the box.
Key Benefits of Freon NU-22B (R-422B):
-
True No-Oil-Change Retrofit: Fully compatible with traditional Mineral Oil (MO), Alkylbenzene (AB), and modern Polyolester (POE) lubricants. You can leave the existing oil in the system, cutting hours off your labor time.
-
Close Performance Match: Closely replicates R-22 operating pressures, meaning it works beautifully with existing TXVs, cap tubes, and pistons without demanding heavy adjustments.
-
ASHRAE A1 Safety Rating: Non-flammable and non-toxic, allowing for standard handling, storage, and transport protocols.
-
Easy Top-Off Servicing: As a stable HFC blend, it can be easily topped off during regular maintenance without requiring a full system recovery and recharge.
-
AHRI-700 Certified Purity: 100% virgin chemical composition eliminates moisture and non-condensable risks, safeguarding the compressor from premature internal failure.
