The Bomag 05542224 Reducing Union is a genuine OEM component designed for BW 184 AD and BW 180 AD tandem rollers and BW 177 D-3, BW 177 DH-3, BW 177 PDH-3, and BW 177 D-3 USA single drum rollers. Sourced directly from Bomag, this reducing union delivers the exact dimensions and thread specifications required for a correct, leak-free installation. As a genuine OEM part, it is manufactured to the same standards as the original component fitted to your machine, ensuring a consistent connection within the hydraulic or fluid circuit.
Key Features
- Genuine OEM Thread Precision — machined to Bomag's exact reducing union specification, ensuring correct thread engagement and a secure, pressure-rated seal at every connection point
- Direct Drop-In Replacement — matches the original port sizing and thread pitch on covered models, fitting directly into the existing fluid line without modification to fittings or hose ends
- Broad Roller Coverage — fits BW 184 AD, BW 184 AD-2, BW 184 AD-2 AM, and BW 180 AD tandem rollers, plus BW 177 D-3, BW 177 DH-3, BW 177 PDH-3, and BW 177 D-3 USA single drum rollers
- Leak-Free Fluid Routing — a correctly installed reducing union maintains full system pressure and flow across differing line diameters; a failed or cross-threaded union can cause fluid loss, pressure drop, and component damage
- OEM Part Number Confidence — ordering by part number 05542224 ensures you receive the exact union specified by Bomag for your machine, eliminating guesswork on sizing
A reducing union is a threaded fitting that connects two fluid lines of different diameters within a hydraulic or coolant circuit, allowing the system to transition between line sizes without interrupting flow or pressure integrity. In Bomag rollers, these unions are critical junctions in the fluid routing network — a worn, cracked, or improperly sized union will cause leaks, reduced system pressure, and potential damage to downstream components. Replacing a failed union promptly with the correct Bomag part restores circuit integrity and keeps the machine operating within its designed performance parameters.
