The Bomag 05543202 Reducing Union is a genuine OEM component designed for the BW 90 AD tandem roller and BW 65, BW 62 H, BW 65 H, BW 65 S-2, BW 65-H, BW 75 AD-2, and BW 75 S-2 walk-behind / light rollers. Sourced directly from Bomag, this reducing union delivers the exact dimensions and thread specifications required for a correct, leak-free installation in the machine's fluid circuit. As a genuine OEM part, it meets the same standards as the original component fitted at the factory, giving you confidence in the repair from the first use. Cross-reference part number 05543202 before ordering to confirm fitment with your specific machine.
Key Features
- Genuine OEM Construction — machined to the original thread form and bore dimensions, ensuring a secure, leak-free connection in the fluid line where an incorrect fitting would allow pressure loss or contamination
- Direct-Replacement Fit — threads into the existing port without reworking fittings or adapting line ends, maintaining the integrity of the original hydraulic or fluid circuit layout
- Broad Roller Coverage — fits the BW 90 AD tandem roller and the BW 65, BW 62 H, BW 65 H, BW 65-H, BW 65 S-2, BW 75 AD-2, and BW 75 S-2 walk-behind / light rollers
- Pressure-Circuit Integrity — a correctly sized reducing union maintains proper flow and pressure between different line diameters; a worn or damaged union can introduce leaks that degrade compaction performance and contaminate surrounding components
- Exact Part Number Match — verified as Bomag part number 05543202, eliminating guesswork and the risk of ordering a mismatched fitting
A reducing union is a threaded connector that joins two fluid lines of different diameters within the machine's hydraulic or fluid system, allowing controlled flow to pass between sections of differing line size without pressure drop or leakage. In compact and walk-behind rollers, these fittings are critical to maintaining the sealed integrity of the system — a failed or cross-threaded union can cause fluid loss, reduced system pressure, and potential damage to downstream components. Replacing a suspect union promptly with the correct OEM part restores the circuit to its original specification and prevents further fluid-side issues.
