The Bomag 05542310 Reducing Union is a genuine OEM component designed for Bomag cold milling machines, refuse/landfill compactors, and recycler/stabilizers across a broad range of heavy equipment models. As a direct OEM replacement, this reducing union is sourced to the same specification as the original, ensuring a correct, trouble-free installation in the hydraulic or fluid plumbing circuit where it is needed. This part fits models including the BM 2000/60-2, BM 2000/75, BM 2200/75, BM 2500/75, BC 972 RB, BC 972 RB-2, BC 1172 RB, BC 1172 RB-2, MPH 121, MPH 122, MPH 122-2, MPH 600, MPH 600 3B/4i-PB, MPH 600 EU-FLEX, BS 12000, BS 12000 Profi, BS 12000 PROFI, RS 650, and BM 2000/75 TE. Ordering by part number 05542310 confirms you are getting the correct union for your machine, eliminating guesswork and costly returns.
Key Features
- Genuine OEM Thread Integrity — Manufactured to Bomag's original thread form and taper specifications, so the union seals correctly under operating pressure without leaks or improvised adaptations.
- Direct Plumbing Replacement — Connects to the existing line fittings in the fluid circuit without reworking adjacent lines or fittings, preserving the original routing and sealing surfaces.
- Broad Heavy-Equipment Coverage — Fits Bomag cold milling machines including the BM 2000/60-2 and BM 2500/75, refuse/landfill compactors including the BC 972 RB and BC 1172 RB, and recycler/stabilizers including the MPH 122, MPH 600, BS 12000 Profi, and RS 650.
- Leak-Free Circuit Reliability — A correctly seated reducing union maintains system pressure and flow rate; a worn or cross-threaded union causes fluid loss, pressure drop, and potential damage to downstream components.
- Verified Part Number Fit — Ordering by Bomag part number 05542310 ensures the correct bore reduction ratio and thread specification for your machine's plumbing circuit.
A reducing union is a hydraulic or fluid-line fitting that joins two lines of different diameters, allowing fluid to pass from a larger-bore line into a smaller-bore line within the same circuit. In heavy equipment like cold milling machines, refuse compactors, and recycler/stabilizers, these fittings appear throughout hydraulic, fuel, coolant, and ancillary fluid systems wherever a line size transition is required. When a reducing union fails — through thread wear, corrosion, or cracking — the affected circuit loses pressure or leaks fluid, which can degrade machine performance or force an unplanned stop. Replacing it with a genuine Bomag part ensures the thread form, sealing taper, and bore dimensions match the original design exactly.
