The Bomag 05557402 AC Hose Assembly WN3111 is a genuine OEM component designed for BC 473-series refuse/landfill compactors and soil compactors, including the BC 473 RB-4, BC 473 RS-4, BC 473 EB-4, BC 473 RB-3, and BC 473 EB-3. As a direct Bomag OEM part, this assembly is manufactured to the exact routing, end-fitting, and pressure specifications of the original — so it connects without modification and restores full air conditioning system integrity from day one. Sourced directly through authorized Bomag supply channels, part number 05557402 is the correct replacement when your existing hose shows wear, cracking, or refrigerant loss.
Key Features
- OEM-Matched Hose Construction — built to the precise inner diameter, reinforcement rating, and refrigerant compatibility of the factory-installed hose, ensuring proper pressure retention in the A/C circuit
- Exact-Fit End Fittings — WN3111-spec connectors align directly with OEM ports on BC 473-series compactors, eliminating the need for adapters or rework during installation
- Broad BC 473 Series Coverage — fits BC 473 RB-4, BC 473 RS-4, BC 473 EB-4, BC 473 RB-3, and BC 473 EB-3 machines, covering both refuse/landfill and soil compactor variants in the BC 473 family
- Restored Cab Climate Control — a properly sealed A/C hose maintains refrigerant charge and system pressure, keeping operator cab cooling effective during demanding compaction cycles
- Genuine Bomag OEM Quality — sourced through the authorized Bomag parts channel, part number 05557402 meets the same material and durability standards as the hose originally fitted at the factory
The AC Hose Assembly WN3111 is a refrigerant-carrying line within the machine's air conditioning system, responsible for transferring pressurized refrigerant between major A/C components such as the compressor, condenser, and evaporator. A sound, leak-free hose is essential for maintaining system pressure — without it, refrigerant escapes, cooling output drops, and the A/C compressor can be damaged from running in a low-charge condition. Replacing a worn or cracked hose with the correct OEM assembly restores the sealed circuit and protects the broader A/C system from secondary damage.
