The Bomag 05542296 Reducing Union is a genuine OEM component designed for Bomag MPH-series recyclers/stabilizers, RS-series recyclers/stabilizers, BS 12000 recyclers/stabilizers, and BC-series refuse/landfill compactors. Sourced directly from Bomag, this reducing union delivers an exact match to the original part in both dimensions and material specification, ensuring a correct, leak-free connection within the hydraulic or fluid circuit. Compatible machines include the MPH 121, MPH 122, MPH 122-2, MPH 125, MPH 600, MPH 600 3B/4i-PB, MPH 600 EU-FLEX, RS 460, RS 500, RS 650, BS 12000, BC 972 RB-2, BC 972 RB-3, BC 972 RB-4, BC 1172 RB-2, BC 1172 RB-3, and BC 1172 RB-4.
Key Features
- Genuine OEM Fluid Integrity — manufactured to Bomag's original material and thread specifications, ensuring a secure, pressure-rated connection that matches the original union precisely
- Drop-In Thread Compatibility — threads and port sizing match the OEM fitting exactly, allowing this reducing union to seat and seal correctly without rework or adaptation to the existing line
- Broad Fleet Coverage — fits MPH 121, MPH 122, MPH 122-2, MPH 125, MPH 600, MPH 600 3B/4i-PB, MPH 600 EU-FLEX, RS 460, RS 500, RS 650, BS 12000, BC 972 RB-2, BC 972 RB-3, BC 972 RB-4, BC 1172 RB-2, BC 1172 RB-3, and BC 1172 RB-4 recyclers/stabilizers and refuse/landfill compactors
- Leak Prevention — a correctly sized and properly seated reducing union maintains system pressure and prevents fluid loss that can lead to hydraulic or fluid-circuit degradation across heavy-duty compaction and stabilization equipment
- Verified Part Number — order with confidence using Bomag part number 05542296, confirmed for the machines listed above
A reducing union is a threaded fitting used to connect two fluid lines of different diameters within a hydraulic or fluid-transfer circuit, stepping down from a larger line to a smaller one while maintaining a sealed, pressure-stable flow path. On heavy equipment such as recyclers, stabilizers, and refuse compactors, these fittings are critical junctions in the hydraulic system — a worn, cracked, or improperly sized union can result in fluid leaks, pressure drops, and ultimately loss of system function. Replacing a failed or damaged union with the correct OEM part restores the integrity of the circuit and keeps the machine operating at full capacity.
