Bomag Air Conditioning Hose | Part 05578128

The Bomag 05578128 Air Conditioning Hose is a genuine OEM component designed for Bomag BW-series single drum rollers, including the BW 177, BW 211, BW 213, BW 214, BW 216, BW 219, and BW 226 families across the -4, -40, -4i, and -5 generation variants. Sourced directly from Bomag, this hose matches the original routing, end fittings, and pressure rating of the factory-installed part, so it installs without rework. If your cab cooling has dropped off or a visual inspection reveals cracking or leaking at the hose, replacing this component with part number 05578128 restores system integrity and protects the rest of the A/C circuit from contamination and pressure loss.

Key Features

• Genuine OEM Construction — built to Bomag's original pressure and temperature specifications for A/C refrigerant hose, using the same materials and end-fitting geometry as the part it replaces
• Direct-Fit Replacement — hose routing, length, and connection ends match the original assembly, allowing the line to seat correctly into existing fittings on the A/C circuit
• Broad Single Drum Roller Coverage — confirmed fitment across BW 177, BW 211, BW 212, BW 213, BW 214, BW 216, BW 219, BW 220, BW 226, and BW 332 single drum rollers, spanning -4, -40, -4i, and -5 generation platforms, including PL, SL, EU-Flex, and DHC variants
• Cab Comfort and Crew Productivity — a functioning A/C system keeps operators alert and effective during long compaction shifts in high-heat conditions; a cracked or leaking hose causes refrigerant loss and total cooling failure
• Refrigerant System Protection — an intact, correctly rated hose prevents moisture and contaminants from entering the closed A/C loop, protecting the compressor, condenser, and expansion valve from premature wear

The air conditioning hose carries refrigerant between the major components of the cab climate system — compressor, condenser, and evaporator — under both high-side and low-side pressures. When the hose degrades, develops cracks, or loses integrity at its fittings, refrigerant escapes, system pressure drops, and the A/C compressor can run dry and seize. Replacing a worn hose promptly with the correct OEM part keeps the entire A/C circuit sealed and performing as designed, preserving operator comfort and avoiding the higher cost of compressor or condenser replacement down the line.
