(1) R454b Refrigerant, Total 8 oz., 4 oz. Oil & 4 oz. Refrigerant R454b
4 oz. R454b Refrigerant & 4 oz. Oil-Lubrication
1/4" male flare hose connection and internal valve core for "self-sealing".
- Made for R454b systems.
- A blend of selected oils that have been formulated to provide the extra oil needed when an R454b air conditioning unit loses the oil charge due to leaks or malfunctions in the system.
** Shake Well Before Use!
A hose with a valve core depressor is required in order to dispense the refrigerant from this can.
We also sell a Part# SF5050 valve for better control of the refrigerant outlet fitting.

Refrigerant R454b is a mildly flammable low global warming potential (GWP) hydrofluoroolefin-based refrigerant to replace R410a in new equipment designs.
R-454B, also known by the trademarked names Opteon XL41, Solstice 454B, and Puron Advance, is a zeotropic blend of 68.9 percent difluoromethane (R-32), a hydrofluorocarbon, and 31.1 percent 2,3,3,3-tetrafluoropropene (R-1234yf), a hydrofluoroolefin.
Because of its reduced global warming potential (GWP), R-454B is intended to be an alternative to refrigerant R-410A in new equipment.
R-454B has a GWP of 466, which is 78% percent lower than R-410A's GWP of 2088.
R-454B is non-toxic and mildly flammable, with an ASHRAE safety classification of A2L.
In the United States, it is expected to be packaged in a container that is red or has a red band on the shoulder or top.
History
The refrigeration industry has been seeking replacements for R-410A because of its high global warming potential.
R-454B, formerly known as DL-5A, has been selected by several manufacturers, including Mitsubishi Electric, Carrier, Johnson Controls, and others.
R-454B was developed at and is manufactured by Chemours.
Carrier first announced introduction of R-454B in ducted residential and light commercial packaged refrigeration and air conditioning products in 2018, with R-454B-based products launches starting in 2023.
Related refrigerants
R-454B is not the only blend of R-32 and R-1234yf to be proposed as a refrigerant.
Other blends include R-454A (35 percent R-32, 65 percent R-1234yf) and R-454C (21.5 percent R-32, 78.5 percent R1234yf).
There are also several blends that include a third component.
