R-454B (A2L) Refrigerant 1.5lb (24 oz) Disposable One-Step Can
Just the refrigerant this is a 24 oz (680 g) disposable one-step can of high-purity Forane® 454B (R-454B) with no gauge, hose, or adapter included. It's the economical choice for the HVAC technician who already runs a manifold gauge set and simply needs a compact, truck-friendly supply of the R-410A replacement refrigerant. The DOT-39 cylinder uses a standard 1/4″ SAE self-sealing valve with right hand threads that connects to your existing charging equipment with a normal clockwise thread. Need the charging tools too? Choose the can with gauge and hose or the mini-split kit with 5/16" service port adapter instead.
Who Is the Can-Only Option For?
This is refrigerant on its own, priced for professionals who already own gauges, hoses, and a manifold set and don't want to pay for tools they don't need. Connect your own charging equipment to the 1/4″ SAE valve and you're ready to work on any R-454B system ducted or, with your own 5/16″ adapter, ductless mini splits as well.
Because R-454B has a very low temperature glide (about 1.1 K), it charges as vapor and tops off cleanly after a leak repair, so the 24 oz size is convenient for topping off and small adjustments without opening a large cylinder.
Ideal for: Technicians who already have their own gauge set and want a compact, standalone 24 oz supply of R-454B. Perfect for small top offs when you don't want to bust out that heavy 20lb jug!
Don't have the tools yet? The gauge-and-hose version (for ducted 1/4″ systems) and the mini-split kit (with the 5/16″ adapter) include everything you need to charge.
Charging guidelines are general references only. Actual requirements depend on system size, line-set length, ambient conditions, and the amount of refrigerant lost. R-454B is an A2L refrigerant for use by qualified HVAC/R professionals. Request equipment help, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
Does this R-454B can come with a gauge or hose?
No. This is the can-only listing. Just the refrigerant with no gauge, hose, or adapter are included. It's meant for technicians who already own a manifold gauge set. For a ready-to-charge package, see the gauge-and-hose version.
What connection does the can valve use?
The cylinder uses a 1/4″ SAE self-sealing valve that threads on with a standard clockwise (right-hand) motion, so it connects to typical charging hoses and manifold sets.
Can I use this can on a mini split?
Yes, if you supply your own 5/16″-to-1/4″ adapter, since mini splits use a 5/16″ port. If you don't already have one, the mini-split kit includes the adapter, gauge, and hose.
What is R-454B and what does it replace?
R-454B (Forane® 454B) is an A2L, low-GWP blend of R-32 and R-1234yf that replaces R-410A in new equipment. With a GWP of 466, it's about 78% lower in global warming potential than R-410A.
Is this the same refrigerant used in the recharge kits?
Yes. All three options use the same 24 oz Forane® 454B disposable can; the difference is only whether charging tools—gauge, hose, and the mini-split adapter—are included.
Do I need a special A2L adapter to connect this can?
No. It uses a standard clockwise 1/4″ SAE valve. The left-thread-to-right-thread A2L adapter is only required for larger refillable cylinders such as 20 lb jugs.
