PROFESSIONAL HVAC REFRIGERANT
R22 REFRIGERANT GAS
30 LB (13.6 KG) CYLINDER
Professional HCFC refrigerant for servicing compatible existing residential and commercial air conditioning and refrigeration systems.
Professional HVAC & Refrigeration Performance
R22 (R-22), also known as HCFC-22 or chlorodifluoromethane, is a single-component refrigerant historically used in residential and commercial air conditioning, heat pumps and refrigeration systems.
Known for its established performance in older cooling equipment, R22 continues to be used for servicing and maintaining compatible existing systems originally designed for this refrigerant.
R22 has an ASHRAE A1 safety classification. However, it has ozone depletion potential and a relatively high global warming potential. New production and import in the United States ended in 2020, while qualifying reclaimed or previously produced supplies may continue to be used for permitted servicing applications.

02 / Cylinder Features & Benefits
Pressure-Resistant Construction
Properly rated refrigerant cylinders are designed to safely contain pressurized R22 during approved storage, transportation and professional handling.
Protective Outer Packaging
Suitable corrugated packaging helps minimize scratches and external surface damage during warehouse handling and shipment.
30 LB Net Refrigerant Capacity
A practical quantity for qualified HVAC technicians servicing existing air conditioning and refrigeration equipment.
Protected Valve Assembly
Compatible protective collars and properly designed cylinder valve assemblies help support secure professional handling.
Existing Equipment Maintenance
Intended for approved service and maintenance work on compatible existing R22 systems.
03 / Recommended Applications
01 — Residential Air Conditioning
R22 is commonly found in older residential central air conditioning and split systems originally designed for this refrigerant. It remains suitable for permitted servicing of compatible existing equipment.
02 — Commercial Air Conditioning
Used for maintenance and repair of compatible existing commercial HVAC systems requiring R22.
03 — Heat Pump Systems
Applicable to older heat pump equipment specifically designed for R22 refrigerant, subject to manufacturer recommendations.
04 — Commercial Refrigeration
Used in certain existing commercial refrigeration installations, including walk-in coolers and older refrigeration systems designed for R22.
05 — Industrial Cooling Systems
May be used for approved servicing of compatible industrial chillers and process cooling systems that originally operated with R22.
04 / Professional HVAC Use
R22 continues to be used in maintenance and repair work on existing compatible refrigeration and air conditioning systems.
Qualified technicians should verify the equipment nameplate, refrigerant compatibility, system pressure, compressor specifications and lubricant requirements before servicing.
Because R22 is a single-component refrigerant, charging methods may use liquid or vapor as permitted by the equipment manufacturer's procedures.
Compatibility Notice: R22 is not a universal replacement for other refrigerants. Do not mix it with R410A, R407C or other refrigerants.
Safety & EPA Compliance
R22 is an ozone-depleting HCFC refrigerant. U.S. production and import of newly manufactured R22 ended January 1, 2020. Permitted servicing of existing equipment may continue using qualifying reclaimed or previously produced R22.
- Use only in legally permitted compatible existing equipment.
- Store cylinders in a cool, dry and ventilated location.
- Protect cylinders against excessive heat and impact.
- Secure cylinders to prevent tipping or damage.
- Use appropriate refrigerant recovery equipment.
- Follow cylinder labeling and Safety Data Sheet instructions.
- Never intentionally vent R22 into the atmosphere.
- Follow EPA Section 608 requirements.
- Verify refrigerant sourcing and applicable resale restrictions.
EPA Purchaser Notice: Refrigerant purchases and installation must comply with applicable certification, resale, reclamation and handling rules. Recovered R22 generally must be properly reclaimed before resale to a different owner for use as refrigerant.
05 / Frequently Asked Questions
What is R22 refrigerant?
R22 is a single-component HCFC refrigerant historically used in residential and commercial air conditioning, heat pumps and refrigeration equipment.
Is R22 still legal in the United States?
Yes, qualifying R22 may still be used to service compatible existing equipment. New domestic production and import ended in 2020, and applicable regulatory restrictions must be followed.
Can R22 be used in new air conditioning systems?
R22 is phased out for new U.S. air conditioning equipment. It is principally used for permitted servicing of existing R22 systems.
Is R22 flammable?
R22 has an ASHRAE A1 classification, indicating no flame propagation under specified standard test conditions.
How much refrigerant is in the cylinder?
This product contains 30 LB (approximately 13.6 KG) of R22 refrigerant.
Can R22 be replaced with R410A?
R410A is not a direct drop-in replacement for R22. The refrigerants operate under different system requirements, and equipment conversion or replacement may be necessary.
What lubricant does R22 use?
Many traditional R22 systems use mineral oil or alkylbenzene lubricant. Always follow the equipment manufacturer's specifications.
Who can purchase R22?
Purchasers must meet applicable EPA refrigerant sales requirements, including appropriate technician certification or qualifying resale conditions.
How should R22 cylinders be stored?
Store securely in a cool, dry, well-ventilated area away from excessive heat, direct sunlight and potential physical damage. Follow the cylinder label and Safety Data Sheet.
