The Bomag 05550963 AC Hose Assembly WN3111 is a genuine OEM air conditioning hose assembly designed for Bomag BW 226 DH-4, BW 226 PDH-4, and BW 226 DH-4i single drum rollers, BM 1000/35, BM 1200/35, BM 1300/35, BM 1000/35-2, BM 1200/35 T4f, BM 1300/35 T4f, BM1200/35-2, and BM1000/35-2 cold milling machines, and the BW 12 R pneumatic tyred roller, as well as the BW 226 DH-4i EU-Flex. As a direct OEM replacement, this assembly matches the original routing, connector fittings, and pressure rating of the factory-installed hose — no adaptation required. Sourced directly from Bomag, part number 05550963 ensures you are installing a component built to the same specification as the original.
Key Features
- OEM-Spec Hose Construction — Built to Bomag's exact pressure rating and inner-diameter specification for air conditioning circuits, ensuring correct refrigerant flow and system integrity.
- Direct Connector Match — End fittings replicate the original WN3111 assembly geometry, connecting to existing AC system ports without reworking lines or brackets.
- Broad Bomag Coverage — Fits BW 226-series single drum rollers, BM-series cold milling machines, and the BW 12 R pneumatic tyred roller, covering a wide range of Bomag equipment.
- Sustained Cab Climate Control — A correctly seated hose assembly maintains refrigerant pressure across the AC circuit; a cracked or degraded hose causes refrigerant loss, compressor strain, and loss of cab cooling.
- Operator Safety Compliance — Maintaining a sealed AC system prevents uncontrolled refrigerant release, supporting safe handling of the refrigerant charge in line with environmental and equipment service requirements.
The AC Hose Assembly WN3111 routes refrigerant between major components in the machine's air conditioning circuit — typically between the compressor, condenser, and evaporator. It must maintain a sealed, pressure-rated connection at all times to keep refrigerant contained and moving efficiently through the system. When this hose degrades, cracks, or its fittings loosen, refrigerant escapes, cab cooling is lost, and the compressor can sustain damage from running low on charge — making prompt replacement with the correct OEM part essential for operator comfort and system longevity.
