PROFESSIONAL HVAC REFRIGERANT
R410A REFRIGERANT GAS
25 LB (11.3 KG) CYLINDER
High-pressure HFC refrigerant for professional servicing of compatible air conditioning, heat pump and HVAC systems.
Professional Air Conditioning Performance
R410A (R-410A) is a near-azeotropic HFC refrigerant blend consisting of R32 and R125 in equal proportions. Developed for high-pressure air conditioning and heat pump equipment, it became widely used in residential and light commercial HVAC applications.
R410A delivers efficient cooling performance in systems specifically engineered for its operating pressures. It is commonly found in existing central air conditioners, split systems, heat pumps, and selected commercial cooling equipment.
R410A has zero ozone depletion potential and an ASHRAE A1 safety classification. However, its relatively high global warming potential means new-equipment use is subject to EPA restrictions. It remains important for permitted servicing of compatible existing HVAC systems.

03 / Recommended Applications
01 — Residential Air Conditioning
Used for permitted maintenance and servicing of existing residential central air conditioning systems originally designed for R410A.
02 — Heat Pump Systems
Suitable for compatible existing heat pumps operating with R410A refrigerant for heating and cooling applications.
03 — Commercial Air Conditioning
Applicable to existing compatible light commercial HVAC systems, packaged air conditioners and split systems requiring R410A.
04 — Mini-Split Systems
Used in professional servicing of compatible ductless mini-split and multi-split air conditioning equipment originally designed for R410A.
05 — HVAC Maintenance
Suitable for qualified technicians performing approved refrigerant recovery, repair, charging and maintenance on existing R410A systems.
04 / Professional HVAC Use
R410A has been widely used in air conditioning and heat pump equipment designed for its relatively high operating pressure.
Qualified technicians should verify the equipment nameplate, POE lubricant specifications, compressor operating pressures and approved service procedures before performing maintenance.
As a near-azeotropic refrigerant blend, R410A is generally charged in the liquid phase using appropriate professional procedures.
Compatibility Notice: R410A operates at substantially higher pressures than R22. It must never be used as a direct drop-in replacement in equipment designed exclusively for R22.
Safety & EPA Compliance
R410A is classified as ASHRAE A1, indicating lower toxicity and no flame propagation under standard testing conditions. Its elevated operating pressure and GWP require appropriate equipment, qualified service and regulatory compliance.
- Use only in R410A-compatible approved equipment.
- Never use R410A as a direct replacement for R22.
- Store cylinders in a cool, dry and well-ventilated location.
- Keep cylinders away from excessive heat and physical damage.
- Use recovery and charging equipment rated for R410A.
- Follow the manufacturer Safety Data Sheet.
- Do not intentionally vent refrigerant into the atmosphere.
- Follow applicable EPA Section 608 requirements.
- Check federal and state restrictions for new system installations.
Regulatory Notice: Existing compatible systems may generally continue to be serviced during their useful life. R410A use in new residential and light commercial systems is restricted under EPA HFC technology-transition rules, subject to applicable exceptions.
Purchaser Notice: Customers must comply with applicable refrigerant sales requirements, including technician certification or qualifying resale exceptions.
05 / Frequently Asked Questions
What is R410A refrigerant?
R410A is a near-azeotropic HFC blend containing 50% R32 and 50% R125, historically used in residential and commercial air conditioning systems.
Can R410A replace R22?
No. R410A operates at significantly higher pressure than R22 and is not approved as a direct drop-in replacement for R22 equipment.
Is R410A flammable?
R410A is classified as ASHRAE A1, meaning no flame propagation under specified standard test conditions.
Which equipment uses R410A?
Many existing central air conditioners, heat pumps, mini-splits and commercial HVAC systems originally designed for R410A.
How much refrigerant is in the cylinder?
This product contains 25 LB (approximately 11.3 KG) of R410A refrigerant.
What oil does R410A require?
Most R410A HVAC equipment uses POE lubricant. Always verify the exact oil requirements specified by the equipment manufacturer.
How should R410A be charged?
R410A should generally be charged in the liquid phase using suitable equipment and approved service procedures.
Is R410A still legal in the United States?
Yes, permitted servicing of existing R410A systems may continue. New system installation is subject to EPA HFC technology-transition rules and applicable exceptions.
Can R454B be mixed with R410A?
No. R454B should not be mixed with R410A or used in equipment that has not been specifically approved for it.
Who can purchase R410A?
Purchasers must meet applicable EPA refrigerant sales requirements, including appropriate certification or qualifying resale conditions.
