The Bomag 05551288 AC Hose Assembly WN3111 is a genuine OEM air conditioning hose assembly designed for a wide range of Bomag tandem rollers, walk-behind / light rollers, pneumatic tyred rollers, and cold milling machines. Sourced directly from Bomag, this part carries the same specifications as the original component installed at the factory. It fits an extensive lineup of BW-series and BM-series machines, including BW 100, BW 120, BW 125, BW 135, BW 138, BW 141, BW 144, BW 151, and BW 154 tandem rollers, BW 75 and BW 71 EHB-2 walk-behind / light rollers, the BW 12 R pneumatic tyred roller, and BM 1000/35-2, BM 1200/35 T4f, and BM 1300/35 T4f cold milling machines. When you need a direct, verified replacement, part number 05551288 is the correct choice.
Key Features
- Genuine OEM Construction — manufactured to Bomag's original hose routing, fitting diameter, and pressure rating specifications, ensuring the AC circuit performs exactly as designed
- Direct-Fit Replacement — ends, fittings, and hose length match the original assembly for a clean, leak-free installation without reworking refrigerant lines
- Broad Fitment Coverage — compatible with Bomag BW 100, BW 120, BW 125, BW 135, BW 138, BW 141, BW 144, BW 151, and BW 154 tandem rollers; BW 75 ADL, BW 75 AD-2, BW 75 AD, and BW 71 EHB-2 walk-behind / light rollers; the BW 12 R pneumatic tyred roller; and BM 1000/35-2, BM 1200/35 T4f, and BM 1300/35 T4f cold milling machines
- Climate System Integrity — a sound hose assembly maintains proper refrigerant flow and pressure, keeping cab temperature controlled for the operator during long compaction or milling shifts
- Refrigerant Leak Prevention — a cracked or deteriorated hose allows refrigerant loss, compressor damage, and cabin heat buildup; replacing with part number 05551288 restores a sealed, pressure-rated circuit
The AC hose assembly is a pressurized refrigerant line that carries refrigerant between the major components of the air conditioning system — typically connecting the compressor, condenser, and evaporator. It must withstand continuous vibration, heat cycling, and the operating pressures of the refrigerant circuit. When a hose cracks, swells, or develops a fitting leak, refrigerant escapes, compressor lubrication degrades, and cab cooling is lost entirely. Replacing the worn hose with a properly rated OEM assembly restores a sealed circuit and protects the downstream AC components from damage caused by low-refrigerant operation.
