The Bomag 05558168 AC Hose Assembly WN3111 is a genuine OEM component designed for Bomag BW 161, BW 190, and BW 202 series tandem rollers. Sourced directly from Bomag, this assembly matches the exact routing, fittings, and pressure ratings of the original hose installed at the factory. It fits a wide range of tandem roller variants, including the BW 161 AD-5, BW 161 ADO-5, BW 161 AD-50, BW 161 ADO-50, BW 190 AD-5, BW 190 ADO-5, BW 202 AD-5, BW 202 ADO-5, BW 202 AD-50, and BW 202 ADO-50, as well as the BW161AD 5, BW190AD 5, and BW161ADO 5. Choosing the correct OEM hose assembly ensures the air conditioning system operates at its designed capacity, keeping operators comfortable on long compaction runs.
Key Features
- Genuine OEM Refrigerant Integrity — manufactured to Bomag's exact pressure and material specifications, so the AC circuit maintains proper refrigerant containment without seepage or pressure drop
- Exact-Match Routing and Fittings — hose length, bend profile, and end fittings correspond directly to part number 05558168, allowing direct installation without cutting, splicing, or adapting
- Broad Tandem Roller Coverage — confirmed fit across BW 161, BW 190, and BW 202 tandem roller variants in both AD and ADO configurations, spanning -5 and -50 generation machines
- Sustained Cab Comfort in Demanding Conditions — a correctly sealed and routed AC hose keeps system pressure stable, ensuring the evaporator delivers consistent cooling during full-shift paving and compaction work
- Refrigerant System Safety — OEM-rated hose construction resists cracking and blowout under operating pressures, preventing uncontrolled refrigerant release that can pose a safety and environmental hazard
The AC Hose Assembly WN3111 is a pressurized refrigerant line that connects key components within the tandem roller's air conditioning circuit, carrying refrigerant between the compressor, condenser, and evaporator. A sound, leak-free hose is essential for maintaining the pressure differential that allows the AC system to cool effectively — even a small crack or loose fitting will cause refrigerant loss and rapid loss of cooling performance. When this hose deteriorates or fails, the cab becomes uncomfortable, operator productivity drops, and refrigerant may escape in a way that requires professional recovery before further service can be carried out.
