The Bomag 05559570 Reducing Nipple is a genuine OEM component designed for Bomag MPH 122-2 and RS 360 TIER-4F recyclers/stabilizers and BM2000/65 Stage V and BM2200/65 Stage V cold milling machines. Sourced directly from Bomag, this part carries the same specifications as the original, ensuring a correct connection within the machine's fluid or pneumatic line routing. If you are servicing an MPH 122-2 recycler/stabilizer or a BM2000/65 Stage V cold milling machine, confirming the correct fitting size and part number 05559570 before ordering is the surest way to keep your repair on track.
Key Features
- Genuine OEM Fitting Integrity — manufactured to Bomag's original thread and taper specifications, so the connection seals correctly under the pressures and fluid conditions these machines generate
- Exact Thread-to-Thread Match — this reducing nipple steps between two line sizes using the original port dimensions, threading in without adaptation to the existing fittings on the host machine
- Broad Heavy-Equipment Coverage — fits MPH 122-2 and RS 360 TIER-4F recyclers/stabilizers, as well as BM2000/65 Stage V and BM2200/65 Stage V cold milling machines
- Leak-Free System Reliability — a properly sized and correctly seated reducing nipple prevents fluid or pressure loss that can lead to system underperformance or unplanned stoppages on demanding recycling and milling applications
- Verified Part Number Traceability — ordering by Bomag part number 05559570 confirms you are receiving the correct nipple for your specific machine, not a generic fitting that may differ in thread form or material grade
A reducing nipple is a threaded fitting that connects two lines or ports of different diameters within a fluid or pneumatic system, allowing flow to transition smoothly between mismatched sizes without requiring a custom adapter. On heavy equipment such as recyclers/stabilizers and cold milling machines, these fittings are integrated into hydraulic, fuel, or air circuits where maintaining a sealed, pressure-rated connection is critical to consistent machine output. When a reducing nipple corrodes, strips, or develops a leak, the affected circuit loses pressure or fluid volume, which can degrade system response and force a work stoppage until the fitting is replaced.
