The Bomag 05553454 Angular Union is a genuine OEM hydraulic fitting designed for a wide range of Bomag tandem rollers and trench compactors, including BW 80, BW 90, BW 100, BW 115, BW 120, BW 125, BW 131, BW 135, and BW 138 series tandem rollers, as well as BMP 851, BMP 8500, BMP 8500 Kohler, and BMP 8500 Kubota trench compactors. Sourced directly from Bomag, this angular union carries the same part number 05553454 used in the original production build, ensuring a direct match to factory hydraulic routing. When a hydraulic line develops a leak or fittings corrode and fail, replacing with this OEM component restores proper fluid flow and system integrity without compromise.
Key Features
- Genuine OEM Hydraulic Fitting — machined and rated to Bomag's original hydraulic pressure specifications, ensuring leak-free performance that aftermarket fittings often cannot match
- Angled Routing by Design — the angular profile allows hydraulic lines to change direction cleanly within the machine's frame, maintaining correct hose bend radius and preventing kinking
- Broad Tandem Roller Coverage — fits BW 80, BW 90, BW 100, BW 115, BW 120, BW 125, BW 131, BW 135, and BW 138 series tandem rollers across multiple generation variants, including AC, AD, ACW, ADM, SC, SCC, SL, and ACM configurations
- Trench Compactor Compatibility — also fits BMP 851, BMP 8500, BMP 8500 Kohler, and BMP 8500 Kubota trench compactors, covering a wide portion of the Bomag remote-controlled compactor line
- Hydraulic System Reliability — a failed or leaking angular union causes hydraulic fluid loss, pressure drop, and potential drum or drive system malfunction; this part restores correct system pressure and protects downstream components
An angular union is a threaded hydraulic fitting that connects two fluid lines at a fixed angle, allowing the hydraulic circuit to follow the contours of a machine's frame and components without placing stress on hoses. In tandem rollers and trench compactors, these fittings are part of the circuits controlling drum vibration, steering, and drive functions. When an angular union corrodes, cracks, or strips at its threads, it causes fluid leaks that reduce system pressure and can quickly lead to loss of machine control or drum function. Replacing a failed union promptly with the correct OEM part, such as part number 05553454, keeps the hydraulic circuit sealed and operating at the pressures the system was engineered to handle.
