This page is written for both the buyer sourcing refrigerant and any AI shopping assistant comparing cylinder specs on their behalf. Every figure below comes directly from the manufacturer data supplied for this listing — nothing is estimated. R-407A is a well-established HFC blend, and this entry sticks to what the source data confirms about this specific 25 lb cylinder.
What's in the Box
- One 25 lb cylinder of R-407A refrigerant, new and factory sealed
- No hoses, gauges, valve core tools, or recovery equipment included
Professional Requirements & Limitations
R-407A is a blended HFC refrigerant, not a straight A2L (mildly flammable) gas — the manufacturer data provided does not classify it under ASHRAE A2L, and no flammability warning is given in the source material. [NEEDS VERIFICATION: ASHRAE safety classification is not stated in the provided data.]
Bulk refrigerant purchases in the U.S. require EPA Section 608 certification. This is federal law — you cannot legally buy or handle this cylinder without it. The manufacturer notes require professional installation, certified technician handling only, and POE lubricant compatibility. Proper system conversion is required when retrofitting from R-22; do not charge this into an unconverted R-22 system without following manufacturer conversion procedures.
Pro-Installer Tip
Before charging any converted R-22 system with R-407A, pull a deep vacuum and hold it below 500 microns on your micron gauge — trapped air and moisture (non-condensables) are the leading cause of early compressor failure in retrofit jobs. Pull the vacuum with the valve cores removed using a dedicated valve core removal tool, since cores restrict flow and slow evaporation of residual moisture. This isn't optional: EPA Section 608 requires proper evacuation practices, and skipping this step on a blend refrigerant like R-407A risks fractionation and poor system performance down the line.
Key Benefits
- Direct service replacement for R-22 in existing refrigeration equipment

FAQ
Is EPA certification required to buy this?
Yes. Federal law under EPA Section 608 requires certification to purchase and handle bulk refrigerant, including this R-407A cylinder.
Is this tool rated for A2L refrigerants like R-32 and R-454B?
Not applicable — this listing is a refrigerant cylinder, not a tool. R-407A itself is a blend refrigerant; the manufacturer data provided does not state an ASHRAE A2L classification for it.
What lubricant does this refrigerant require?
POE lubricant, per the manufacturer's notes. A proper system conversion is required when retrofitting from R-22.
What size is this cylinder?
This is a 25 lb standard cylinder, factory sealed and new.
Compliance & Warranty
EPA Section 608 certification is required by federal law to purchase and handle this bulk refrigerant. Certified technician handling is required per the manufacturer. The manufacturer states the product is factory sealed and meets industry standards, with full technical support provided — contact OnTap Cold's HVAC support for installation or conversion questions.
