The Bomag 05550007 Banjo Union is a genuine OEM hydraulic fitting designed for a broad range of Bomag tandem rollers, walk-behind rollers, and trench compactors. Sourced directly from Bomag, this banjo union delivers the exact dimensions, thread specification, and sealing integrity required to maintain a leak-free hydraulic connection. This fitting is confirmed compatible across the BW 90 AD, BW 100 AD-5, BW 120 AD-5, BMP 8500, and many additional models in Bomag's tandem roller and walk-behind lineup. When hydraulic fittings wear, corrode, or develop leaks, replacing them with a genuine OEM component like this banjo union ensures the system returns to correct operating pressure without compromise.
Key Features
- Genuine OEM Hydraulic Integrity — manufactured to Bomag's original thread form and seating geometry, ensuring the sealing surfaces mate correctly and hold rated system pressure without weeping or leakage
- Direct-Fit Hydraulic Connection — installs into the same port and orientation as the original fitting, requiring no thread chasing, adapters, or line rerouting
- Broad Bomag Coverage — fits BW-series tandem rollers from the BW 60 S and BW 90 AD through the BW 138 AD-5 and BW 131 ACW-5, plus BW 6 and BW 65 HS walk-behind rollers and BMP 851 and BMP 8500 trench compactors
- Leak-Free System Pressure — a correctly seated banjo union keeps hydraulic fluid routed precisely where the system demands it; a failed or cross-threaded fitting leads to pressure drop, fluid loss, and potential component damage
- Verified Part Number Confidence — ordering by Bomag part number 05550007 eliminates guesswork on thread size and body dimensions across this wide fitment range
A banjo union is a hollow-bolt hydraulic fitting that allows a fluid line to connect to a ported surface at a fixed angle while permitting the hose or tube end to swivel freely during installation. It consists of a hollow bolt, a domed banjo eye, and sealing washers that compress against the mating surfaces to form a leak-tight joint under hydraulic pressure. When the fitting cracks, strips, or loses its sealing face, hydraulic fluid bypasses the joint, causing pressure loss that can affect steering, vibration drive, or propulsion systems — making prompt replacement with a correctly specified part essential to safe machine operation.
