Use R404A only in compatible commercial refrigeration and cold-storage equipment.
Purchase, recovery, charging, and service should be handled by appropriately certified personnel.
The cylinder contains 24 lb (10.9 kg) net weight of R404A. Verify the label, valve, seal, and cylinder condition.
R404A should normally be transferred from the cylinder in the liquid phase and charged by weight.
R404A has a high GWP, so system owners may wish to discuss future replacement or retrofit planning with a refrigeration professional.
Not sure whether your refrigeration system uses R404A? Send support the equipment label, compressor model, and application.
Use R404A only in equipment designed or formally approved for R404A. Do not mix it with R407A, R448A, R449A, or another refrigerant. Before purchasing, check the equipment nameplate and manufacturer documentation. If you are unsure, send us a clear photo of the nameplate and consult a qualified technician.
R404A refrigerant blend is intended for compatible commercial refrigeration, cold-storage, and food-processing equipment. The listed applications are general guidance only; the equipment nameplate and manufacturer specification determine the correct refrigerant.
The cylinder contains 24 lb (10.9 kg) net weight of R404A refrigerant. Net contents do not include the cylinder tare weight or outer packaging. Verify the product label, seal, and cylinder condition when the shipment arrives.
No. Refrigerants are not interchangeable and should not be mixed. Use only the refrigerant approved for the equipment. Any conversion or retrofit must follow the equipment or retrofit manufacturer's written requirements and be completed by a qualified professional.
Recovery, charging, leak testing, and system repair should be performed by a qualified refrigeration professional using equipment approved for R404A. Purchasing, handling, recovery, transport, and installation requirements may vary by product, application, and location. Confirm the rules that apply to you before ordering or using the product.
Shipping is free on U.S. orders. Orders ship from the United States within 24 business hours, and estimated delivery is 2–5 business days. Tracking is provided after dispatch. Carrier and hazardous-material restrictions may apply.
Do not use the cylinder if it is leaking, the valve is damaged, or the package appears unsafe. Keep it away from heat, flames, and occupied indoor areas, and do not attempt a repair. Contact support with the order number and clear photos of the cylinder, valve, damage, packaging, shipping label, and batch code so the issue can be reviewed.
A return must be requested within 30 days. Only unused, unopened cylinders in their original condition and packaging are eligible. Contact support for approval before returning regulated goods. Specialized carrier requirements may apply, return shipping costs are the customer's responsibility, and refunds are issued after inspection.
Bulk pricing may be available depending on quantity, destination, inventory, freight requirements, and applicable shipping restrictions. Send the required quantity, cylinder size, delivery ZIP code or country, company details, and requested delivery date for a confirmed quotation.
