R-454B Refrigerant 24 oz Disposable One-Step Can with Gauge & Hose (1/4″ SAE Right Hand Clockwise Connection)
Charge R-454B ducted split systems and heat pumps without hauling a full manifold set. This 24 oz (680 g) disposable one-step can pairs high-purity Forane® 454B (R-454B) refrigerant with a built-in pressure gauge and charging hose, so an HVAC technician can top off or complete a charge straight from the can. It connects to a standard 1/4″ SAE low-side service port with a normal clockwise right hand thread, making it ideal for residential and light-commercial central air conditioners and heat pumps that use the R-410A A2L replacement refrigerant, R-454B. This kit is built for ducted equipment, if you service ductless equipment, choose the Mini-Split R-454B Recharge Kit with the 5/16″ adapter instead.
Is This the Right R-454B Can for Your Job?
This one-step can is sized for field service. Topping off after a leak repair, finishing a charge, or handling small adjustments on 1/4″ SAE ducted split systems. Because R-454B has a very low temperature glide (about 1.1 K), it can be added as vapor and tops off cleanly, so a 24 oz can goes a long way on typical residential service calls.
Use it on central air conditioners and heat pumps originally designed for R-454B. Actual refrigerant needed depends on line-set length, system tonnage, and how much charge was lost, so always charge to the equipment manufacturer's target subcooling or superheat rather than by the can.
Ideal for: Residential and light-commercial ducted R-454B air conditioners and heat pumps with a 1/4″ SAE service port.
Servicing a ductless system? Every mini split uses a 5/16″ service port. Step over to the Mini-Split R-454B Recharge Kit, which includes the required 5/16″-to-1/4″ adapter.
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 help selecting a system, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
What systems is the 24 oz R-454B can with gauge and hose for?
It is designed for ducted R-454B split systems and heat pumps—central air conditioners and heat pumps that use a standard 1/4″ SAE service port. It is not intended for ductless mini splits, which require a 5/16″ adapter.
Do I need a left-thread to right-thread A2L adapter for this can?
No. These 24 oz cans thread on with a standard clockwise (right-hand) 1/4″ SAE connection. The 1/4″ SAE Left-Thread-to-Right-Thread A2L adapteris only needed for larger refillable cylinders, such as 20 lb jugs, which use left-hand threads.
How many pounds of refrigerant is in a 24 oz can?
A 24 oz can holds 1.5 lb (680 g) of R-454B. Because R-454B has a very low glide, it can be charged as vapor and topped off after a leak repair, so a single can covers many typical residential service adjustments.
Can R-454B be used to top off an R-410A system?
No. R-454B is a replacement for R-410A in equipment specifically designed for R-454B; it is not a drop-in for existing R-410A systems. Use it only in equipment built for R-454B. Metering devices and Compressors can become severely damaged if R454B is used in an R410A designed system.
Is a license required to buy R-454B refrigerant?
R-454B is an A2L refrigerant intended for qualified HVAC/R professionals. Always follow federal, state, and local regulations along with the equipment manufacturer's A2L service procedures. If not purchasing for resell we would need an EPA card uploaded in order to fulfill your order.
