This is a 22 lb factory-sealed cylinder of R-454B refrigerant, an A2L low-GWP replacement for R-410A. It ships new, not reclaimed or reprocessed.
What This Is
Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
R-454B is a hydrofluoroolefin (HFO) blend developed to replace R-410A and R-22 in new air conditioning, heat pump, and refrigeration equipment. Manufacturer data describes it as offering lower global warming potential than R-410A along with strong energy efficiency across residential, commercial, and industrial cooling and heating applications. The cylinder in this listing is 22 lb, new, and factory sealed.
What's In The Box
You get one 22 lb cylinder of R-454B refrigerant, factory sealed. No hoses, gauges, recovery equipment, or fittings are included with this purchase.
Professional Requirements & Limitations
Federal law under EPA Section 608 requires technician certification to purchase and handle regulated refrigerants, including R-454B. Have your EPA 608 credentials ready before you order — MSSD cannot ship bulk refrigerant without verifying certification status where required.
R-454B falls in the A2L category of refrigerants, which ASHRAE classifies as mildly flammable [NEEDS VERIFICATION — manufacturer data did not state the ASHRAE class number in the source text]. Treat it with the same handling precautions as other A2L blends: no open flame near recovery or charging operations, and confirm that any vacuum pump, recovery machine, or leak detector you pair with this cylinder is rated spark-proof and A2L compatible. The manufacturer data provided does not specify GWP value, cylinder pressure, or charging weight limits — those figures are [NEEDS VERIFICATION].
Pro-Installer Tip
Pulling a vacuum on a system charged with an A2L blend like R-454B carries more risk than it does with R-410A if your pump or hoses aren't rated for it. Non-condensables and moisture left behind from a shallow vacuum accelerate compressor wear and can create pressure spikes in a flammable-refrigerant system — a bigger deal with A2L gas in the loop. Use a spark-proof vacuum pump paired with a micron gauge, and pull the system down below 500 microns, holding that vacuum to confirm no leak-back before charging. EPA Section 608 requires proper evacuation practice on any regulated system, and ASHRAE's A2L safety guidance is the reason spark-proof tooling isn't optional here — it's the standard.

Compatibility & Fitment
Compatible with: New air conditioning systems, commercial refrigeration equipment, and heat pump systems designed for R-454B per manufacturer application guidance.
Not compatible with / not included: This is refrigerant only — hoses, manifold gauges, recovery machines, and fittings are NOT included. Do not use this refrigerant in systems designed exclusively for R-410A or R-22 without manufacturer confirmation that the equipment is rated for R-454B. Any vacuum pump, recovery machine, or leak detector used with this refrigerant must be independently confirmed spark-proof and A2L-rated; compatibility of your existing tools is NOT guaranteed by this listing.
FAQ
Is EPA certification required to buy this?
Yes. EPA Section 608 certification is required by federal law to purchase and handle this refrigerant.
Is this tool rated for A2L refrigerants like R-32 and R-454B?
This listing is the R-454B refrigerant itself, not a tool. R-454B is an A2L-classified blend, and any tools you use with it — vacuum pumps, recovery machines, leak detectors — must be confirmed spark-proof and A2L compatible separately.
What is the cylinder weight?
22 lb, factory sealed, new.
Compliance & Warranty
Purchase of this refrigerant requires valid EPA Section 608 certification, as mandated by federal law. R-454B is an A2L (mildly flammable) refrigerant class; follow manufacturer and ASHRAE safety guidance for storage, handling, and equipment compatibility. Manufacturer warranty terms, safety data sheets, and full specifications are available under the "Resources (System Manuals and Warranty)" Tab above. MSSD does not alter or supplement the manufacturer's stated warranty coverage.
