The Bomag 05556721 AC WN3111 Hose Assembly is a genuine OEM component designed for BW 161 and BW 202 series tandem rollers, including the BW 161 AD-5, BW 161 AC-5, BW 161 AD-50, BW 161 ADO-5, BW 161 ADO-50, BW 161 AC-50, BW 190 AD-5, BW 190 ADO-5, BW 202 AD-5, BW 202 AD-50, BW 202 ADO-5, and BW 202 ADO-50. Sourced directly from Bomag, this hose assembly carries the same specification as the original factory component, ensuring a correct connection without adaptation. Confirmed fitment across the BW 161 and BW 202 tandem roller families makes part number 05556721 a straightforward choice when replacing a worn or damaged hose on your machine.
Key Features
- Genuine OEM Hose Integrity — manufactured to Bomag's original pressure rating and material spec, so the assembly delivers the same service life as the part it replaces
- Direct OEM Replacement — engineered to the same routing, end fittings, and length as the original, connecting correctly to existing ports without rework
- Broad Tandem Roller Coverage — fits BW 161 and BW 202 series tandem rollers including AD-5, AC-5, ADO-5, AD-50, ADO-50, and AC-50 variants, as well as BW 190 AD-5 and BW 190 ADO-5 machines
- Sustained System Flow — a correctly seated hose assembly maintains proper fluid delivery and pressure, keeping the AC circuit operating as designed and preventing performance loss from leaks or restrictions
- Leak and Pressure Risk Reduction — a cracked or degraded hose can cause fluid loss, system contamination, or circuit failure; replacing with an OEM assembly restores the sealed integrity of the circuit
A hose assembly routes pressurized fluid between system components, maintaining the flow and pressure required for the circuit to function correctly. In a tandem roller's AC system, a failed or leaking hose disrupts fluid delivery, which can lead to reduced system output, component wear from starvation, or unplanned shutdowns. Replacing a worn hose assembly with an OEM part restores the sealed, pressure-rated connection the system depends on to perform consistently across a full compaction shift.
