The Bomag 05551756 AC Hose Assembly is a genuine OEM replacement designed for the BMP 851 trench compactor, BW 900 AD tandem roller, and BW 900-2 walk-behind roller. Sourced directly from Bomag, this assembly matches the original specifications for routing, end fittings, and hose construction — ensuring a correct, leak-free connection within the air conditioning circuit. If you're working on part number 05551756, you can order with confidence knowing this is the exact component Bomag specifies for these machines.
Key Features
- Genuine OEM Hose Construction — Built to Bomag's original pressure rating and routing geometry, maintaining proper refrigerant containment and flow within the AC system.
- Direct-Fit End Fittings — Factory-matched connectors align with OEM port positions on the BMP 851, BW 900 AD, and BW 900-2, allowing installation without rerouting or adapter fittings.
- Confirmed Fitment Across Three Machine Families — Verified for the BMP 851 trench compactor, BW 900 AD tandem roller, and BW 900-2 walk-behind roller.
- Leak Resistance Under Operating Pressure — OEM hose material and crimped end fittings resist refrigerant permeation and pressure cycling that can cause aftermarket assemblies to fail prematurely.
- Refrigerant System Integrity — A compromised AC hose can release refrigerant, reducing cabin cooling performance and potentially creating a compliance issue — replacing with the correct OEM assembly restores full system function.
The AC hose assembly is a pressurized conduit within the machine's air conditioning circuit, carrying refrigerant between components such as the compressor, condenser, and evaporator. It must maintain a sealed, flexible connection across temperature extremes and engine vibration — conditions that cause hoses with incorrect material ratings or ill-fitting ends to crack, seep, or disconnect. When this hose degrades, the AC system loses pressure, refrigerant escapes, and operator cab cooling fails entirely, making prompt replacement with the correct OEM part essential to restoring climate control performance.
