This air conditioning hose carries refrigerant between the compressor and the evaporator within the tractor cabin's climate system. It connects the high-pressure discharge line to the condenser or the expansion valve, depending on the specific loop layout. A cracked or leaking hose causes a loss of refrigerant charge, which results in reduced cooling capacity or complete system failure. This original AGCO part is formed to the same bend radius and end-fitting orientation as the original assembly, which allows it to route through the existing chassis clips without kinking. When replacing, install new O-rings at each connection and evacuate the system before charging.
