The Bomag 05551047 AC Hose Assembly WN3111 is a genuine OEM air conditioning hose assembly designed for the MPH 121 and MPH 122 recycler/stabilizers, as well as the BPR 40/45 D, BPR 40/45 D-2, BPR 40/45 D-3, BPR 50/52 D, and BPR 50/52 D-3 reversible vibratory plates. Sourced directly through Bomag's authorized parts network, this assembly matches the original routing, fittings, and pressure ratings of the factory-installed hose. Confirmed fitment across both the MPH-series recyclers and the BPR-series reversible plates means you can order with confidence that part number 05551047 is the correct component for your machine.
Key Features
- Genuine OEM Pressure Rating — manufactured to the exact pressure and temperature tolerances of the original Bomag AC system, ensuring proper refrigerant containment and system integrity
- Correct Routing and End Fittings — hose length, bend profile, and connector fittings match the original installation points, allowing direct installation without rerouting or adapting
- Broad Confirmed Fitment — verified for MPH 121 and MPH 122 recycler/stabilizers and BPR 40/45 D, BPR 40/45 D-2, BPR 40/45 D-3, BPR 50/52 D, and BPR 50/52 D-3 reversible vibratory plates
- Operator Cab Comfort Restored — a failed or leaking AC hose causes refrigerant loss and complete loss of cooling; replacing it with this assembly restores full climate control for the operator
- Refrigerant System Safety — a compromised hose can release refrigerant under pressure; an OEM-spec replacement maintains sealed system integrity and supports safe AC service compliance
The AC Hose Assembly WN3111 is a pressurized refrigerant line that carries conditioned refrigerant between components of the machine's air conditioning system — typically between the compressor, condenser, and evaporator. Keeping this hose intact is essential for maintaining cabin cooling and operator comfort during long working shifts. When the hose cracks, chafes, or develops a leak, refrigerant escapes, the AC system loses pressure, and cooling performance drops off entirely — making prompt replacement critical for both comfort and system longevity.
