Certification Required
Please check the EPA certification box before adding this item to your cart.
A full pallet of R-422B (NU-22B) — 40 factory-sealed 25 lb cylinders, 1,000 lb of refrigerant, shipped on one skid with freight included to the lower 48. The R-22 replacement you reach for when you're keeping older AC and heat pump systems running without a full retrofit.
R-422B (NU-22B) is an A1 (non-flammable) HFC blend designed as a service replacement for R-22 in air conditioning and heat pump systems. It's a practical retrofit choice for the large base of legacy R-22 equipment still in the field — no oil change required in most cases — which keeps it in steady demand for service work.
Why buy R-422B by the pallet
- One price, one shipment, free freight. A full pallet ships LTL freight on us — no stacked per-cylinder hazmat surcharges.
- Keep the R-22 fleet alive. Plenty of R-22 systems are still running — a pallet of 422B keeps you topping them off all season without re-ordering.
- 100% virgin, ARI-700 compliant. Factory-sealed cylinders with documentation for your EPA records — not reclaimed or grey-market.
