The Yellow Jacket 19124 1/4" Hose Adapter is designed specifically for use with modern A2L refrigerants such as R-32 and R-454B. This straight adapter converts a 1/4" left-hand female flare connection to a 1/4" right-hand male flare connection, allowing HVAC technicians to safely connect charging hoses and service equipment to A2L refrigerant tanks.
Built with professional-grade materials, the adapter features Yellow Jacket’s patented CH14 “adjust-a-valve” opener for smooth refrigerant flow and compatibility with or without a Schrader core. The double-ring knurl design makes left-hand connections easy to identify, helping improve safety and reduce connection errors in the field.
