The Bomag 05542298 Reducing Union is a genuine OEM component designed for a broad range of Bomag pavers, cold milling machines, refuse and landfill compactors, soil compactors, and single drum rollers. As a direct OEM replacement, this reducing union meets Bomag's original engineering specifications for a drop-in installation with no guesswork on sizing or thread compatibility. Confirmed fitment includes BF 600-series pavers, BM-series cold milling machines including the BM 2000/75, BM 2200/75, and BM 2500/75, BC-series refuse/landfill compactors such as the BC 572 RB-2, BC 671 RS, BC 772 RB-4, and BC 772 RS-4, BC-series soil compactors including the BC 772 EB-2, BC 772 EB-4, BC 672 EB-2, and BW 172 D-2 and BW 142 D-2 single drum rollers. Sourcing part number 05542298 directly through DHS Equipment ensures you receive an authenticated Bomag part backed by the manufacturer's quality assurance.
Key Features
- Genuine OEM Fluid-Line Integrity — manufactured to Bomag's original thread and bore specifications, ensuring a leak-free hydraulic or fluid-system connection with no risk of pressure loss from mismatched fittings
- Direct-Fit Installation — engineered to the exact port dimensions of the original reducing union, so this part seats correctly without thread adapters or rework
- Broad Cross-Fleet Coverage — fits BF 600-series pavers, BM-series cold milling machines, BC-series refuse/landfill compactors, BC-series soil compactors, and BW-series single drum rollers, making it a versatile stocking part for mixed Bomag fleets
- Sustained System Pressure — a correctly functioning reducing union maintains proper fluid-flow transition between lines of different diameters; a worn or failed union can cause leaks, pressure drops, and unplanned machine downtime
- Fluid-System Safety — OEM-spec material and sealing surfaces prevent hydraulic or fuel-line weeping that can create fire hazards or contaminate surrounding components on high-hour machines
A reducing union is a pipe or hose fitting that connects two fluid lines of different diameters, allowing fluid to pass from a larger bore to a smaller bore — or vice versa — while maintaining a sealed, pressure-rated joint. In heavy construction equipment, reducing unions appear in hydraulic circuits, fuel delivery lines, and cooling systems wherever a line diameter changes between components. When the union degrades, cracks, or develops thread damage, the resulting leak can starve downstream components of fluid, trigger pressure faults, or introduce air into a closed circuit, all of which compromise machine operation and can escalate into costlier component failures if left unaddressed.
