Bomag 05551077 AC Hose Assembly

The Bomag 05551077 AC Hose Assembly is a genuine OEM component designed for a broad range of Bomag single drum rollers, tandem rollers, recyclers/stabilizers, and pavers — including the BW 172 D-2, BW 142 D-2, BW 202 AD-2, BW 202 AHD-2, BW 174 AC, BW 174 AC-2, BW 174 ACP, BW 100 AD-5, BW 100 AC-5, BW 100 SL-5, BW 120 AC-5, BW 120 AD-5, BW 120 SL-5, BW 161 AD-2, BW 164 AD-2, BW 174 AC AM, BW 174 AC-2 AM, BW 174 ACP-AM, MPH 122, MPH 122-2, BF 700 C-3 S 500, BF 700 C-3 S 600, and BF 800 C-3 S 600. As a factory-sourced replacement, this assembly carries the same specifications as the original part it replaces, ensuring a correct, trouble-free installation. When the existing hose shows signs of cracking, leaking, or heat damage, swapping in part number 05551077 restores the air conditioning circuit to full working condition without improvisation or adaptation.

Key Features

• Genuine OEM Construction — sourced directly from Bomag, this hose assembly is manufactured to the exact pressure ratings, inner diameter, and end-fitting specifications of the original AC line
• Direct-Fit Replacement — end fittings and hose routing match the OEM layout on covered machines, allowing the assembly to connect to existing ports and brackets without rework
• Wide Model Coverage — confirmed fitment across Bomag single drum rollers including the BW 172 D-2 and BW 142 D-2, tandem rollers including the BW 100 and BW 120 series and the BW 174 and BW 202 families, MPH 122 and MPH 122-2 recyclers/stabilizers, and BF 700 and BF 800 series pavers
• Operator Comfort Restored — a correctly sealed and routed AC hose maintains refrigerant pressure so the cabin cooling system can regulate cab temperature, keeping operators productive during long shifts in warm conditions
• Refrigerant Containment Compliance — a sound, OEM-spec hose prevents refrigerant loss that would otherwise require system recharging and may trigger environmental compliance obligations on regulated jobsites

The AC hose assembly carries refrigerant between the major components of the machine's air conditioning circuit — compressor, condenser, expansion valve, and evaporator. When this hose degrades or develops a leak, refrigerant escapes, cabin cooling drops off, and the compressor can be damaged by running without adequate charge. Replacing the hose with the correct OEM assembly, part number 05551077, seals the circuit and allows the full AC system to function as intended.
