R-453A / RS-44B Refrigerant — 25 lb Cylinder

100% Virgin, Premium-Grade R-22 Replacement Refrigerant for Compatible Legacy Systems

Extend the service life of compatible legacy air-conditioning and refrigeration equipment with this 25 lb factory-sealed cylinder of 100% virgin R-453A refrigerant, commonly marketed as RS-44B. Designed as an R-22 replacement option for approved applications, R-453A provides dependable cooling performance while offering a lower global warming potential than R-22.

Its formulation is intended to simplify servicing and retrofit work on compatible systems, helping qualified HVAC/R technicians transition away from R-22 where the equipment manufacturer and applicable regulations permit its use.

What's Included

• 25 lb Factory-Sealed Cylinder — Contains 100% virgin R-453A / RS-44B refrigerant for professional HVAC/R applications.

• A1 Safety Classification — Classified as non-flammable with lower toxicity under the applicable refrigerant safety classification system.

• Factory-Sealed Packaging — Helps protect the refrigerant from contamination before use.

Key Benefits

• R-22 Replacement Option — Designed for use in compatible R-22 systems where R-453A has been approved for the application and retrofit procedures are followed.

• Simplified Retrofit Potential — May allow servicing of compatible systems with limited modifications compared with some alternative refrigerant conversions. Always follow the equipment manufacturer's requirements.

• Lubricant Compatibility — Formulated for compatibility with lubricants used in many existing R-22 applications, but oil, component, and system compatibility must be verified before charging.

• Lower-GWP Alternative to R-22 — Provides a reduced global warming potential compared with R-22 while maintaining dependable cooling performance in approved applications.

• 25 lb Professional Capacity — Practical cylinder size for qualified technicians performing system conversions, charging, maintenance, and service work.

Important Safety & Compliance Information

A1 Safety Classification: R-453A is classified as A1 (lower toxicity and non-flammable) under the applicable refrigerant safety classification system. Proper handling procedures, appropriate service equipment, and established safety practices must still be followed.

Verify System Compatibility: R-453A should be used only in systems specifically approved for the refrigerant or properly converted in accordance with applicable manufacturer and industry procedures. Verify refrigerant, lubricant, component, pressure, and system compatibility before charging.

Professional Use Only: Refrigerant recovery, charging, retrofit conversion, leak testing, and servicing should be performed by appropriately trained and qualified HVAC/R technicians in accordance with manufacturer instructions and applicable safety requirements.

Regulatory Compliance: R-453A is a fluorinated greenhouse gas and may be subject to environmental regulations, phase-down requirements, sales restrictions, recovery requirements, recordkeeping provisions, and other applicable rules depending on your jurisdiction. Verify all local, state, federal, and national requirements before purchasing, handling, or using the product.
