The Bomag 05558728 Hose Assembly AC WN3111 is a genuine OEM hose assembly designed for the BC 772 RB-4 and BC 772 RS-4 refuse/landfill compactors, the BC 672 RB-4 refuse/landfill compactor, and the BC 772 EB-4 soil compactor. Sourced directly from Bomag, this assembly matches the original routing, end fittings, and pressure rating specified for these machines — no guesswork on compatibility. Whether you're servicing a BC 672 RB-4 refuse compactor or a BC 772 EB-4 soil compactor, part number 05558728 delivers the exact OEM replacement your machine requires.
Key Features
- Genuine OEM Hose Construction — manufactured to Bomag's original pressure rating and hose material spec, ensuring the assembly handles the fluid demands of heavy-cycle compactor operation without weeping or premature failure
- Direct-Fit Routing and End Connections — end fittings and hose length match the original assembly, so this component seats correctly in the existing mounts and connections without modification
- Broad BC-Series Coverage — fits the BC 772 RB-4, BC 772 RS-4, and BC 672 RB-4 refuse/landfill compactors, as well as the BC 772 EB-4 soil compactor
- Sustained Fluid System Integrity — a correctly routed, intact hose assembly maintains consistent flow and pressure to the circuit it serves; a cracked or deteriorated hose causes fluid loss, contamination, and potential system shutdown on the workface
- Fluid System Safety — a failed high-pressure hose on a landfill or soil compactor presents a real risk of fluid injection injury and fire hazard; replacing with a genuine OEM assembly rated to spec keeps operators protected
A hose assembly connects two points in a machine's fluid circuit — hydraulic, coolant, or fuel — carrying pressurized fluid between components such as pumps, valves, cylinders, and coolers. On large compactors like the BC 772 and BC 672 series, these hoses operate under sustained pressure and exposure to heat, vibration, and abrasion. When a hose assembly cracks, swells, or blows a fitting, the affected circuit loses pressure, leading to reduced or total loss of function in the system it serves — whether that's steering, drive, or implement control. Replacing a worn or damaged assembly promptly with a genuine OEM part restores full system pressure and prevents cascading damage to pumps and other downstream components.
