R-454B A2L Refrigerant 20.9 lb Jug — Low-GWP Replacement for R-410A
R-454B is the low-GWP A2L refrigerant that has replaced R-410A in many new residential air conditioners and heat pumps, and this 20.9 lb jug is the full-charge supply for installing and servicing them. It's a blend of 68.9% R-32 and 31.1% R-1234yf (HFC and HFO) with a GWP of 466 and zero ozone depletion potential. A2L cylinders use a left-hand-thread valve, so you can add the 1/4″ SAE left-to-right thread adapter at checkout if you need one. Purchase requires EPA Section 608 certification. For a small top-off, the R-454B 24 oz can with gauge and hose is easier to carry.
Is the 20.9 lb R-454B Jug the Right Size?
This jug is for contractors installing new R-454B equipment, recharging after a repair, or servicing several R-454B systems. It costs less per pound than small cans and holds enough for full system charges, such as on Rheem R-454B heat pump systems.
R-454B is classified A2L, meaning mildly flammable, so use A2L-rated tools and handling practices. R-454B is not a drop-in for R-410A systems. Only charge equipment designed and labeled for R-454B.
Ideal for: HVAC contractors installing and servicing new R-454B central air conditioners and heat pumps.
Only need a top-off? The R-454B 24 oz can handles small charge adjustments.
Refrigerant purchases require the Refrigerant Agreement and proof of EPA Section 608 certification. R-454B is an A2L refrigerant for use by qualified HVAC/R technicians following A2L handling practices. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.
