The Bomag 05553711 Union is a genuine OEM component designed for Bomag BC-series refuse and landfill compactors and BW-series single drum rollers. Sourced directly from Bomag, this union carries the same specifications as the part that left the factory, ensuring a correct, trouble-free installation. Compatible models include the BC 601 RS, BC 601 RB, BC 570 RB, BC 571 RB, BC 670 RB, BC 671 RS, BC 672 RB, BC 771 RB, and a broad range of BW single drum rollers spanning the BW 177, BW 179, BW 213, BW 214, BW 216, BW 218, BW 219, and BW 226 series. Always confirm your machine's model code before ordering to ensure an exact application match.
Key Features
- Genuine OEM Construction — manufactured to Bomag's own material and dimensional standards, ensuring the union seals and connects hydraulic or fluid lines exactly as the original did
- Direct OEM Replacement — matches the original mounting thread, port size, and body geometry so this union installs into the existing fitting location without rework or adapters
- Broad Cross-Family Fitment — verified for BC-series refuse and landfill compactors including the BC 601 RB, BC 672 RB, and BC 771 RB, as well as BW-series single drum rollers from the BW 177 through the BW 226 family
- Leak-Free Fluid Integrity — a correctly functioning union maintains a sealed, pressure-rated connection in the fluid circuit; a worn or damaged union can introduce leaks that compromise hydraulic or cooling system performance
- Verified Part Number Traceability — ordering by Bomag part number 05553711 eliminates fitment guesswork and confirms you are receiving the exact component for your specific machine variant
A union is a threaded pipe or hydraulic fitting that joins two sections of a fluid line, allowing the circuit to be assembled, disassembled, and reconnected without cutting or deforming the lines themselves. On heavy compaction equipment, unions appear in hydraulic circuits, engine cooling systems, and fuel delivery lines, where they carry pressurized fluid between components such as pumps, coolers, and control valves. When a union corrodes, cracks, or develops a compromised seal, it can leak fluid under pressure, causing system pressure loss, contamination of surrounding components, or a complete circuit failure — making timely replacement essential to keeping the machine operating at full capacity.
