R454c Refrigerant, 4 oz. Eco-Friendly R134a Replacement

R454c Refrigerant, 4 oz. Eco-Friendly R134a Replacement Contains 4 liquid ounces. The top cylinder connection is 1/4" male flare with internal valve core for self-sealing. You can connect any 1/4" hose, that has a valve core depressor, directly to the cylinder for dispensing the gas. If your hose does not have a valve core depressor, or you want better control, then we recommend you add a "SF5050" dispensing valve to your cart. This will connect to the cylinder and has a on/off valve and a 1/4 male flare hose connection. DESCRIPTION: R454C refrigerant is a Low GWP  hydrofluoro-olefin (HFO) based refrigerant replacement for R404A and R22. R454C is a close match to R22 based technology, but it is also a valid solution for R404A equipment. With a GWP 148, it falls under the important maximum value of 150 in the F-Gas regulation. Classified as mildly flammable (A2L), R454C allows much higher charge sizes than other flammable refrigerants and can be safely used by following the applicable codes and standards.
