| | RC04 Series Dual-Line ConnectAire™ Couplings | |
| | | |
| | Parker's RC04 dual-line ConnectAire™ couplings are used to connect liquid and suction line for mini-split air conditioning and heat pump systems. Applications up to 2 tons can also include portable air conditioners, split refrigeration systems, remote condensing units, and beverage cases. Application ■ Split refrigeration systems ■ Mini-split air conditioning and heat pump systems up to 2-tons ■ Portable air conditioners Base Product Part Number ■ RC04-A01-6666, A02-6666, A01-6664 Male Coupling ■ RC04-B02-6664, B02-6666, B04-6666 & B05-6565 Female Coupling | Features and Benefits ■ Simultaneously and quickly connects both liquid and vapor lines without the use of tools. ■ Self-sealing upon disconnection maintains minimum air inclusion and fluid loss. ■ Brass coupling provides corrosion resistance. ■ Copper-sweat connections provide basic ends for brazing and eliminate the need for flux, simplifying the installation process. ■ Panel mounting options are available for the unique needs of a unit. | | |
