    AI Overview
    R421A is a non-ozone depleting, HFC zeotropic blend (58% R125, 42% R134a) designed as a direct, non-flammable (A1) drop-in replacement for R22 in AC and refrigeration systems
    . It works with existing mineral, AB, or POE oils, requiring no system modifications or oil changes. Key suppliers include iCool USA Inc., USA Refrigerant, and RGAS LLC. 
    Key Features and Specifications: 
    • Applications: Residential, commercial, and industrial, including medium/high-temperature applications.
    • Performance: Offers similar operating pressures and capacity to R22, allowing for simple recovery and recharging.
    • Compatibility: Compatible with existing R22 equipment, including gauges and line sets.
    • Components: 58% R-125 and 42% R-134a.
    • Packaging: Commonly available in 25 lb and 110 lb cylinders.
    • Safety: Non-toxic, non-flammable (ASHRAE A1 rated). 
    Important Information: 
    • No Hydrocarbons: Unlike some alternatives, R421A does not contain butane or isobutane.
    • Charging: Should be charged as a liquid to manage its slight fractionation.
    • Replacement: It is a direct, drop-in replacement, making it ideal for retrofitting older R22 systems without major maintenance.
