Use R1234yf only in vehicles designed or formally approved for this refrigerant.
Technicians servicing MVAC systems for consideration must meet applicable EPA Section 609 training and certification requirements.
The cylinder contains 11 lb (5 kg) net weight of R1234yf. Verify the label, valve, seal, and cylinder condition before use.
Use only equipment, fittings, recovery cylinders, and lubricant procedures approved for R1234yf MVAC systems.
Store the cylinder upright in a cool, dry, well-ventilated location and follow the Safety Data Sheet.
Not sure whether the vehicle uses R1234yf? Send support a photo of the under-hood refrigerant label and vehicle model year.
Use R1234yf only in vehicles specifically designed and labeled for R1234yf. Do not add it to an R134A, R12, or other MVAC system. 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.
HFO-1234yf is intended for compatible R1234yf motor-vehicle air-conditioning systems. The listed applications are general guidance only; the equipment nameplate and manufacturer specification determine the correct refrigerant.
The cylinder contains 11 lb (5 kg) net weight of R1234yf 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.
R1234yf is an A2L refrigerant with lower flammability. Service requires dedicated R1234yf equipment and an appropriately qualified motor-vehicle A/C technician. 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.
