The Bomag 05553855 Quick Coupling is a genuine OEM component designed for Bomag BW 141 AD-4, BW 154 AD-4 AM, BW 161 AD-4, BW 161 ADH-4, BW 202 AD-4, and BW 203 AD-4 AM tandem rollers. As a direct factory replacement, this coupling delivers the exact fit and hydraulic compatibility your machine requires. Sourced from Bomag's authorized parts supply, part number 05553855 ensures you're installing the same component built to the original design specification. This Quick Coupling is the right choice when restoring hydraulic line integrity on any of the covered tandem roller models.
Key Features
- Genuine OEM Hydraulic Integrity — manufactured to the same tolerances and pressure ratings as the original, ensuring leak-free hydraulic connections on your tandem roller
- Direct Drop-In Replacement — connects to existing hydraulic lines and ports without rework, maintaining the original routing and sealing geometry
- Broad Tandem Roller Coverage — fits BW 141 AD-4, BW 154 AD-4 AM, BW 161 AD-4, BW 161 ADH-4, BW 202 AD-4, and BW 203 AD-4 AM tandem rollers
- Sustained System Pressure — a correctly seated quick coupling keeps hydraulic circuits fully pressurized, supporting consistent drum vibration and drive performance on the job
- Fluid Contamination Control — OEM coupling design minimizes air ingestion and fluid loss during connection and disconnection, protecting downstream hydraulic components
A quick coupling is a self-sealing hydraulic connector that allows pressurized lines to be joined or separated rapidly without significant fluid loss. On Bomag tandem rollers, these couplings are used throughout the hydraulic system to link circuits for drum drive, vibration, and steering functions. When a quick coupling wears, cracks, or fails to seat correctly, the result is hydraulic fluid leakage, pressure drop, and degraded machine performance — and in severe cases, complete loss of a driven function. Replacing a faulty coupling promptly with a correct OEM part restores full system pressure and prevents secondary damage to pumps, motors, and seals downstream.
