    AI Overview
    R421A Refrigerant 25 LBS HALF PALLET (20 Cylinders) – Frznx
    R421A is a non-ozone depleting, HFC-based zeotropic blend (58% R125 / 42% R134a) designed as a direct "drop-in" replacement for R22 in HVAC and refrigeration systems. It requires no oil changes (compatible with mineral, AB, or POE oils) or system modifications. It is non-flammable, rated A1 by ASHRAE. 
    Key Features and Benefits: 
    • Performance: Mimics R22 pressures and temperatures, offering similar cooling capacity.
    • Compatibility: Compatible with existing R22 gauges, components, and POE/Mineral oil.
    • Drop-in: No, or minimal, system modifications required (replacing the filter drier is recommended).
    • Versatility: Suitable for residential and commercial AC, heat pumps, and refrigeration.
    • No Hydrocarbons: Contains no R600 (isobutanes or isopropanes). 
    Installation & Handling: 
    • Charging: Must be charged as a liquid to prevent fractionation.
    • Topping Off: Because of its low glide, systems can be "topped off" after leaks.
    • Lubricant: It is often packaged with a proprietary lubricant to assist with oil return. 
    R421A is commonly sold in 25 lb or 30 lb cylinders, with costs often ranging between
