The Bomag 59420402 Orifice is a genuine OEM component designed for the MPH 121, MPH 122, and MPH 122-2 recycler/stabilizer machines. Sourced directly from Bomag, this orifice delivers the exact dimensional and flow specifications required to keep hydraulic or fluid circuits performing as engineered. If you are servicing an MPH 121, MPH 122, or MPH 122-2 and need a verified OEM part, the part is the correct replacement to restore proper system function.
Key Features
- Genuine OEM Flow Precision — manufactured to Bomag's exact bore and passage tolerances, ensuring the fluid restriction or metering function performs exactly as the original circuit demands
- Direct Replacement Fit — engineered to drop into the same port or fitting location as the original, with no reworking of lines or fittings required
- Confirmed Fitment — verified for Bomag MPH 121, MPH 122, and MPH 122-2 recycler/stabilizer machines
- Consistent System Pressure and Flow — a correctly sized orifice maintains the calibrated flow rate that protects downstream components and keeps the hydraulic or fluid circuit balanced under load
- OEM Part Number Accuracy — ordering by Bomag part number 59420402 eliminates the guesswork of cross-referencing and confirms you receive the right component the first time
An orifice is a precisely sized restrictive passage built into a hydraulic or fluid circuit to regulate flow rate and control pressure drop between system sections. By metering fluid movement, it protects actuators, valves, and pumps from pressure spikes and ensures that each circuit branch receives the correct share of flow. When an orifice becomes blocked, eroded, or incorrectly sized, the affected circuit can suffer sluggish response, component overload, or uncontrolled pressure fluctuations — all of which compromise the performance and reliability of the recycler/stabilizer during soil mixing and stabilization passes.
