R-421A 25lb Refrigerant Cylinders & Pallets

R-421A, also marketed as Choice™ R-421A, is an HFC blend specifically designed as a direct retrofit for R-22. It’s valued for being a “no oil change” solution, fully compatible with both mineral oil and POE oil, which reduces labor costs during conversions.

Our 25lb R-421A cylinders are factory sealed, EPA-compliant, and DOT-certified for safe transport. Whether you need singles for service work or bulk pallets for regular R-22 retrofits, AAA Refrigerant provides a reliable nationwide supply.
