The Bomag 80290103 Orifice is a genuine OEM component designed for Bomag BW 80 AD-2, BW 90 AD-2, BW 100 ADM-2, BW 80 ADS, and BW 90 AC-2 tandem rollers. Sourced directly from Bomag, this orifice meets the exact dimensional and flow specifications of the original part. It installs directly into the hydraulic circuit without modification, restoring proper fluid regulation across the full range of compatible machines.
Key Features
- Genuine OEM Flow Calibration — manufactured to Bomag's precise orifice diameter specification, ensuring correct hydraulic fluid metering with no guesswork
- Direct-Fit Installation — matches the original port threading and body dimensions for a straightforward drop-in replacement in the hydraulic circuit
- Broad Tandem Roller Coverage — fits BW 80 AD-2, BW 90 AD-2, BW 100 ADM-2, BW 80 ADS, and BW 90 AC-2 tandem rollers, covering multiple variants within Bomag's compact tandem lineup
- Consistent Pressure Regulation — a correctly sized orifice maintains stable hydraulic pressure differentials, supporting smooth drum drive and vibration system response
- Fuel and Hydraulic System Integrity — using the correct OEM-spec orifice prevents uncontrolled flow rates that can stress downstream hydraulic components and cause erratic machine behavior
An orifice is a precisely sized flow-restriction fitting within a hydraulic circuit, controlling the rate at which fluid passes between system circuits or components. By metering flow at a fixed rate, it regulates pressure balance and response speed across hydraulic functions such as drum drive or vibration. When an orifice becomes blocked, eroded, or incorrectly sized, hydraulic functions can behave erratically — delivering too much or too little flow — which puts unnecessary strain on pumps, motors, and valves throughout the system.
