Bomag 05556720 Hose Assembly AC WN3111

The Bomag 05556720 Hose Assembly AC WN3111 is a genuine OEM replacement designed for BW 161 and BW 202 series tandem rollers. Sourced directly from Bomag, this assembly matches the original routing, connection dimensions, and pressure ratings of the factory-installed hose — no adaptation needed to achieve a proper fit. This hose assembly is compatible across a broad range of BW 161 and BW 202 tandem roller variants, including the BW 161 AD-5, BW 161 AC-5, BW 161 ADO-5, BW 161 AD-50, BW 161 AC-50, BW 161 ADO-50, BW 190 AD-5, BW 190 ADO-5, BW 202 AD-5, BW 202 ADO-5, BW 202 AD-50, and BW 202 ADO-50. As a genuine Bomag part, part number 05556720 delivers the same service life and performance characteristics as the original component it replaces.

Key Features

• Genuine OEM Construction — manufactured to Bomag's original hose specifications, including correct inner diameter, reinforcement layer, and end-fitting configuration for this AC circuit application
• Direct Drop-In Replacement — matches the original routing path and connection points on BW 161 and BW 202 tandem rollers, allowing straightforward installation without reworking fittings or brackets
• Broad Tandem Roller Coverage — fits BW 161 AD-5, BW 161 AC-5, BW 161 ADO-5, BW 190 AD-5, BW 190 ADO-5, BW 202 AD-5, BW 202 ADO-5, and additional AD-50 and ADO-50 variants
• Sustained System Integrity — a correctly seated hose assembly maintains proper fluid delivery and pressure within the AC circuit, preventing leaks that can compromise compaction performance or cause system damage
• Operator Safety Assurance — a failing or degraded hose in a pressurized circuit can lead to fluid loss or unexpected system behavior; replacing with a genuine Bomag assembly restores designed system containment

The Hose Assembly AC WN3111 carries pressurized fluid through a specific circuit on the tandem roller — in this case, the AC (compaction or accessory circuit) routing defined by the WN3111 specification. A hose assembly in this position must maintain a leak-free seal under sustained operating pressure and vibration, both of which are constant on a vibratory tandem roller. When the hose degrades — through cracking, fitting loosening, or abrasion — the circuit loses pressure, affecting machine output and creating a potential fluid hazard on the worksite. Replacing it with part number 05556720 restores the original sealed circuit and full system function.
