The most versatile and comprehensive drop-in replacement for R-22. Our 25 lb Freon™ MO99 (R-438A) Virgin Cylinder is the premier choice for retrofitting residential air conditioning, commercial HVAC systems, and low-to-medium temperature refrigeration units.
Engineered to match R-22 mass flow, capacity, and operating pressures, R-438A allows you to update aging systems to comply with modern environmental regulations without expensive component changes. Every cylinder arrives factory-sealed to guarantee 100% virgin purity right out of the box.
Key Benefits of Freon MO99 (R-438A):
-
No Oil Changes Required: Uniquely compatible with traditional Mineral Oil (MO), Alkylbenzene (AB), and modern Polyolester (POE) lubricants—eliminating the need for costly and time-consuming oil flushes.
-
Direct R-22 Expansion Valve Match: Designed to maintain a near-identical capacity match, meaning you don't have to overhaul your TXVs or line sets.
-
ASHRAE A1 Safety Rating: Certified non-flammable and non-toxic, ensuring traditional handling safety and eliminating the strict storage codes of newer flammable alternatives.
-
AHRI-700 Certified Purity: 100% virgin chemical composition prevents internal moisture buildup and shields compressors from accelerated acid wear.
-
Broad System Adaptability: Highly effective in rooftop package units, split systems, DX chillers, walk-in coolers, and supermarket rack systems.
