Bomag 05556719 AC WN3111 Hose Assembly

The Bomag 05556719 is a genuine OEM AC WN3111 Hose Assembly designed for Bomag tandem rollers across the BW 161, BW 190, BW 191, BW 202, and BW 206 series. Sourced directly from Bomag, this assembly delivers an exact match to the original specification, ensuring proper routing, connection, and sealing within the machine's air conditioning circuit. Compatible models include the BW 161 AD-5, BW 161 AC-5, BW 161 AD-50, BW 161 AC-50, BW 161 ADO-5, BW 161 ADO-50, BW 190 AD-5, BW 190 ADO-5, BW 191 AD-5, BW 191 AD-5 AM, BW 191 ADO-5, BW 202 AD-5, BW 202 AD-50, BW 202 ADO-5, BW 202 ADO-50, BW 206 AD-5, BW 206 AD-5 AM, BW 206 AD-50, BW 206 ADO-5, BW 206 ADO-50, BW161AD 5, BW190AD 5, BW161AC 5, and BW161ADO 5 tandem rollers. When the original hose assembly cracks, leaks, or loses integrity, replacing it with part number 05556719 restores the AC system to proper working order without guesswork or modification.

Key Features

• Genuine OEM Hose Integrity — manufactured to Bomag's original pressure and temperature ratings for AC circuit hose assemblies, so the connection holds under continuous compaction-duty operating conditions
• Direct-Connect Replacement — matches the original hose length, end fittings, and routing path, allowing this assembly to swap directly into the existing AC circuit without rerouting or adapting
• Broad Tandem Roller Coverage — fits BW 161, BW 190, BW 191, BW 202, and BW 206 series tandem rollers including AD-5, AC-5, AD-50, AC-50, ADO-5, and ADO-50 variants, as well as AM-spec machines
• Restored Cab Climate Control — a failed or leaking AC hose causes refrigerant loss and complete loss of cooling; replacing it with this assembly returns the cab environment to a safe and productive operating temperature for operators on long paving shifts
• Refrigerant System Protection — a correctly sealed hose assembly prevents refrigerant escape, protecting the compressor and other AC components from running in a low-charge condition that accelerates wear and can lead to compressor failure

The AC WN3111 Hose Assembly carries refrigerant between components in the tandem roller's cab air conditioning system, maintaining the closed-loop pressure needed for effective cooling. A hose that has cracked, perished, or worked loose at its fittings will bleed refrigerant, causing the system to underperform or shut down entirely and leaving the operator without climate control in hot paving conditions. Replacing a worn hose assembly promptly with part number 05556719 protects the broader AC circuit and keeps the cab environment safe and comfortable throughout the working day.
