The Bomag 05558921 AC Hose Assembly is a genuine OEM component designed for Bomag BW 174 AP-4f, BW 174 AP-4f AM, BW 174 AP-4v AM, and BW 174 APO-4f tandem rollers, MPH 364-2 and RS 360 TIER-4F recyclers/stabilizers, and BM2000/65 Stage V and BM2200/65 Stage V cold milling machines. Sourced directly from Bomag, this assembly delivers an exact OEM fit with no guesswork on routing, connections, or dimensions. Confirming part number 05558921 against your machine's serial plate before ordering ensures a straightforward installation and keeps your air conditioning system operating at full capacity.
Key Features
- OEM-Grade Refrigerant Line Construction — Built to Bomag's original pressure ratings and hose material specifications, maintaining correct refrigerant flow and leak-free sealing throughout the AC circuit.
- Direct OEM Replacement — Engineered to match the original routing path, end fittings, and connection points so this assembly installs without modification to brackets or line supports.
- Broad Equipment Coverage — Fits BW 174 AP-4f, BW 174 AP-4f AM, BW 174 AP-4v AM, and BW 174 APO-4f tandem rollers, MPH 364-2 and RS 360 TIER-4F recyclers/stabilizers, and BM2000/65 Stage V and BM2200/65 Stage V cold milling machines.
- Cab Comfort Protection — A correctly functioning AC hose assembly sustains proper system pressure, enabling efficient cabin cooling that keeps operators productive in hot working conditions.
- Refrigerant System Safety — A cracked or failing hose can release refrigerant and depressurize the AC circuit; replacing it with a genuine OEM assembly restores system integrity and prevents uncontrolled refrigerant loss.
The AC Hose Assembly is a pressurized refrigerant line that carries conditioned refrigerant between the compressor, condenser, and evaporator in the machine's air conditioning system. It maintains the sealed, pressurized circuit necessary for the AC system to absorb and transfer heat efficiently, keeping the operator cab at a controlled temperature during long compaction or milling shifts. When the hose cracks, swells, or develops a leak, refrigerant escapes, system pressure drops, and the AC loses cooling capacity entirely — making prompt replacement with a correctly specified assembly essential to restoring full cab comfort.
