Bomag 05550978 Air Conditioning Hose Assembly

The Bomag 05550978 Air Conditioning Hose Assembly is a genuine OEM component designed for a wide range of Bomag pavers, tandem rollers, refuse and landfill compactors, soil compactors, and cold milling machines — including BF 600 series pavers, BW tandem rollers, BC compactors, and BM cold milling machines. Sourced directly from Bomag, this hose assembly carries the exact routing geometry, end fittings, and pressure rating of the original part it replaces. Verified against Bomag part number 05550978, this assembly delivers a direct, accurate fit across the full breadth of compatible equipment.

Key Features

• Genuine OEM Construction — Built to Bomag's original pressure ratings and hose routing specifications, ensuring the A/C circuit operates at the correct refrigerant flow capacity without improvised bends or adapters.
• Direct-Fit End Fittings — Engineered with OEM-matched connection points that mate precisely to existing ports, eliminating the need for fitting modifications during installation.
• Broad Equipment Coverage — Compatible with BF 600 series pavers, BW tandem rollers (including BW 80, BW 90, BW 100, BW 120, BW 125, BW 135, BW 138, BW 141, BW 151, BW 154, BW 161, BW 164, BW 172, BW 190, BW 202, BW 203, and BW 205 variants), BC refuse, landfill, and soil compactors, and BM 500/15 and BM 600/15 cold milling machines.
• Cabin Comfort and Operator Productivity — A properly functioning A/C hose maintains refrigerant containment and flow pressure, keeping the cab cooling system working at full capacity — critical for operators during long shifts in hot conditions.
• Refrigerant System Integrity — A cracked, kinked, or degraded hose allows refrigerant to leak, which not only disables cab cooling but can also result in compressor damage and environmental compliance issues — making prompt hose replacement essential.

The air conditioning hose assembly is a pressurized refrigerant line that carries refrigerant between the major components of the cab's A/C system — typically between the compressor, condenser, and evaporator. It maintains the sealed, pressurized circuit that allows the system to transfer heat out of the cab and deliver cooled air to the operator. When this hose deteriorates, cracks, or loses its end-fitting seal, refrigerant escapes, system pressure drops, and the A/C compressor can run dry and sustain internal damage — making this hose a critical service item for maintaining operator comfort and protecting the wider A/C system.
