The Bomag 05557590 AC Hose Assembly WN3111 is a genuine OEM component designed for Bomag BW-series tandem rollers, including the BW 100 AD-5, BW 120 AD-5, BW 161 AD-5, BW 190 AD-5, and BW 202 AD-5 families. Sourced directly from Bomag, this hose assembly matches the original specification for a direct, hassle-free installation. It covers an extensive range of fifth-generation tandem roller variants — including ADO, AC, SL, and CC configurations — so you can order with confidence that this is the correct part for your machine.
Key Features
- Genuine OEM Construction — manufactured to Bomag's original hose routing and pressure ratings, ensuring the AC system operates exactly as designed on your tandem roller
- Direct-Fit Replacement — engineered with the correct end fittings, length, and bend geometry to seat into existing mounting points without reworking lines or brackets
- Broad Tandem Roller Coverage — fits BW 100 AD-5, BW 100 SL-5, BW 120 AD-5, BW 120 AD-5 CC, BW 120 SL-5, BW 161 AC-5, BW 161 AD-5, BW 161 ADO-5, BW 190 AD-5, BW 190 ADO-5, BW 202 AD-5, and BW 202 ADO-5 tandem rollers
- Sustained Cab Comfort — a sound AC hose keeps refrigerant contained at the correct pressure, maintaining consistent cooling performance for the operator during long compaction shifts
- Refrigerant Integrity — a cracked or failed hose allows refrigerant loss, which not only disables cab cooling but can also result in regulatory non-compliance; replacing with a genuine hose restores a sealed, compliant system
The AC Hose Assembly WN3111 is a pressurized refrigerant line that carries conditioned refrigerant between components of the air-conditioning system — typically between the compressor, condenser, and evaporator. It must maintain a leak-free seal under continuous vibration and varying temperature cycles, which is especially demanding on a vibratory tandem roller. When this hose cracks, kinks, or develops a leak, refrigerant escapes, the AC system loses pressure, and cab cooling fails — leaving operators exposed to heat on the jobsite. Replacing the hose with a genuine Bomag part numbered this part restores a fully sealed circuit and returns the system to normal operating pressure.
