The Bomag 05554706 AC Hose Assembly WN3111 is a genuine OEM component designed for BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, and BW 120 AC-4 tandem rollers. Sourced directly from Bomag, this assembly matches the original routing, connector specifications, and pressure ratings of the factory-installed hose. Fitment is confirmed across the full BW 100 and BW 120 AC/AD-4 tandem roller range, so you can order with confidence knowing this is the correct part for your machine.
Key Features
- Genuine OEM Air Conditioning Grade — built to the same pressure and material standards as the original, ensuring the AC circuit holds charge and resists refrigerant permeation over time
- Exact-Match Hose Routing — WN3111 designation confirms this assembly matches the original connector ends, hose diameter, and length for a direct swap with no trimming or adapting
- Confirmed Tandem Roller Coverage — fits BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, and BW 120 AC-4 tandem rollers, covering both the BW 100 and BW 120 AC/AD-4 series
- Cab Comfort Restored — a sound AC hose assembly keeps refrigerant circulating properly so the operator cab maintains effective cooling during long paving shifts
- System Integrity Protected — a cracked or leaking AC hose causes refrigerant loss, compressor strain, and eventual system failure; replacing with part number 05554706 restores a sealed, fully pressurized circuit
An AC hose assembly carries refrigerant under pressure between the major components of the air conditioning system — compressor, condenser, and evaporator. It must maintain a leak-free seal across a wide range of operating temperatures and vibration levels, both of which are demanding conditions on a ride-on tandem roller. When this hose cracks, kinks, or loses a fitting seal, refrigerant escapes, the system loses cooling capacity, and the compressor can overheat from running without adequate lubrication. Replacing the assembly promptly with the correct OEM part keeps the cab environment safe and comfortable for the operator throughout the workday.
