The Bomag 05551857 AC Hose Assembly is a genuine OEM component designed for the BC 571 RB, BC 671 RB, and BC 771 RB refuse/landfill compactors. Sourced directly from Bomag, this assembly matches the original routing, fittings, and pressure ratings of the factory air conditioning line it replaces. If your cab cooling has dropped off or you've spotted a refrigerant leak along the AC circuit, replacing this hose assembly with part number 05551857 restores the system to full working order. It is the straightforward, like-for-like fix for operators who need their cab environment back under control fast.
Key Features
- Genuine OEM Pressure Integrity — manufactured to Bomag's original hose specification, ensuring the AC circuit holds the correct refrigerant pressure without seepage or line fatigue
- Exact-Route Replacement — pre-formed to the factory bend profile so the assembly seats cleanly into the existing brackets and connection points without reworking the hose path
- Confirmed Fitment — verified for BC 571 RB, BC 671 RB, and BC 771 RB refuse/landfill compactors, covering the full RB series of these machines
- Cab Comfort Restored — a failing AC hose starves the system of refrigerant, leading to warm cab temperatures and operator fatigue on long compaction shifts; this assembly brings the cooling circuit back to full capacity
- Refrigerant System Safety — a properly sealed, OEM-spec hose prevents uncontrolled refrigerant release, protecting both the technician performing service and the surrounding environment
An AC hose assembly carries pressurized refrigerant between the major components of the air conditioning system — compressor, condenser, and evaporator — keeping the cab cool and the operator comfortable during operation. When a hose cracks, chafes through, or its end fittings weaken, refrigerant escapes and the entire AC circuit loses the pressure it needs to transfer heat effectively, resulting in little or no cooling output. Replacing a worn or leaking hose assembly promptly prevents secondary damage to the compressor and other AC components that can occur when the system runs low on refrigerant.
