The Bomag 05550026 Banjo Union is a genuine OEM hydraulic fitting designed for BW 145 and BW 177 series single drum rollers, including the BW 145 D-5, BW 145 PDH-5, BW 177 D-5, BW 177 DH-5, BW 177 PDH-5, and BW 177BVC-5. Sourced directly from Bomag, this banjo union matches the original component specification for a drop-in installation with no adaptation needed. Confirming part number 05550026 against your machine's service documentation before ordering is always recommended to ensure correct fitment.
Key Features
- Genuine OEM Hydraulic Integrity — manufactured to Bomag's original flow-path and sealing specifications, so the banjo union maintains correct hydraulic pressure and leak-free connections in demanding single drum roller applications
- Direct-Fit Installation — replicates the original banjo-style bolt pattern and port geometry for a straightforward swap with your existing hydraulic line hardware
- Broad BW 145 and BW 177 Coverage — confirmed fitment across the BW 145 D-5, BW 145 PDH-5, BW 177 D-5, BW 177 DH-5, BW 177 PDH-5, and BW 177BVC-5 single drum rollers
- Leak-Free Hydraulic Circuit — a correctly seated banjo union keeps hydraulic fluid routed precisely where it needs to go, protecting downstream components from pressure drop and contamination
- Hydraulic Line Safety — a worn or cracked banjo union can result in hydraulic fluid loss and sudden pressure failure; replacing it with a genuine OEM part helps maintain safe, controlled machine operation
A banjo union is a hollow bolt-and-fitting assembly that connects a hydraulic line to a port on a component such as a pump, motor, or valve block, allowing fluid to flow through the center of the bolt while the banjo eye seals flat against the mating surface. On heavy single drum rollers like the BW 145 and BW 177 series, these fittings carry pressurized hydraulic fluid that powers propulsion, vibration, and steering functions. When a banjo union cracks, strips, or loses its sealing surface, the resulting leak starves the hydraulic circuit of fluid and pressure, leading to erratic machine behavior and potential component damage if not addressed promptly.
