A full pallet of genuine Honeywell Solstice® 454B (R-454B) — 40 factory-sealed 20 lb cylinders, 800 lb of refrigerant, on one skid with freight included to the lower 48. Built for HVAC contractors and distributors stocking up on the R-410A replacement before the busy season.

R-454B is the low-GWP, A2L refrigerant that the major equipment makers chose to replace R-410A in new residential and light-commercial air conditioners and heat pumps. It carries roughly 78% lower GWP than R-410A with very similar capacity and efficiency, which is why it's the gas going into most 2025-and-newer systems. Buy it by the pallet and you're covered for every new install and warranty job on your board.

Why buy R-454B by the pallet

• One price, one shipment, free freight. A full pallet ships LTL freight on us — no stacked per-cylinder hazmat surcharges from shipping bottles one at a time.
• Don't get caught short on new equipment. Every R-410A system you sell now ships with 454B. Keeping a pallet on hand means you're never turning down an install because you're out of gas.
• Genuine Honeywell, every cylinder. Factory-sealed and virgin — not repackaged or grey-market. Documentation ships with the pallet for your EPA records.
