The Bomag 05556378 AC Hose Assembly WN3111 is a genuine OEM air conditioning hose assembly designed for Bomag BW 80 AD-5, BW 90 AD-5, BW 90 SC-5, BW 100 ADM-5, BW 100 ACM-5, BW 100 SC-5, and BW 100 SCC-5 tandem rollers. Sourced directly from Bomag, this assembly matches the original routing, end fittings, and pressure ratings of the factory-installed hose — no guesswork, no adaptation. As a genuine OEM component, part number 05556378 ensures the AC system seals and flows exactly as Bomag engineered it, keeping the operator cab climate-controlled and the refrigerant circuit intact across the full BW-series tandem roller lineup.
Key Features
- OEM-Spec Refrigerant-Grade Construction — Built to Bomag's original pressure rating and hose material spec, maintaining proper refrigerant containment and AC system efficiency on your tandem roller.
- Direct-Fit Routing and End Fittings — Hose length, bend geometry, and connector ends match the original assembly so this component installs into the existing AC circuit without modification.
- Broad BW-Series Tandem Roller Coverage — Confirmed fitment across BW 80 AD-5, BW 90 AD-5, BW 90 SC-5, BW 100 ADM-5, BW 100 ACM-5, BW 100 SC-5, and BW 100 SCC-5 tandem rollers.
- Leak-Free AC Circuit Integrity — A correctly seated hose assembly prevents refrigerant loss that would otherwise cause the cab to overheat and force operator downtime in demanding paving conditions.
- Genuine Bomag OEM Part — Supplied as an authentic Bomag replacement under part number 05556378, backed by the same quality control as the original factory-installed component.
The AC hose assembly carries refrigerant between the major components of the air conditioning system — compressor, condenser, and evaporator — under high and low-side pressure. A sound, properly routed hose keeps the refrigerant circuit sealed so the cab cooling system can maintain comfortable operating temperatures for the roller operator. When a hose degrades, cracks at a fitting, or develops a leak, refrigerant escapes, AC output drops, and the system can sustain compressor damage if run low on charge. Replacing a worn hose with the correct OEM assembly restores full system pressure and protects every other component in the AC circuit.
