R-454B 5 LBS.

R454B 5 lbs of refrigerant is contained in this order. Empty tare weight is 8.2 lbs, and the box weight is 1 lb.

R454B is a hydrofluoroolefin (HFO) and hydrofluorocarbon (HFC) refrigerant blend, used as a low global warming potential (GWP) alternative to R410A in residential and commercial air conditioning systems. It consists of R32 and R1234yf and provides significantly lower GWP while maintaining similar cooling performance and energy efficiency.

It operates at similar pressure levels to R410A, making it suitable for system replacement with minimal modifications. R454B is mildly flammable (A2L classification), so proper handling and safety precautions are required. Its reduced environmental impact and efficiency make it a strong option for modern HVAC systems and retrofits. The cylinder valve is a 1/4″ SAE reverse thread to comply with regulations.
