The Bomag 05541721 Union is a genuine OEM fitting designed for a range of Bomag pavers, single drum rollers, and recycler/stabilizers. Sourced directly from Bomag, this union delivers an exact match to the original component it replaces, ensuring correct thread engagement and a leak-free hydraulic or fluid-line connection. This union is confirmed to fit the BF 600 P-2 S 500, BF 600 P-3 S 500, and BF 800 P S500 pavers, the BW 212 D-2 and BW 213 D single drum rollers, and the MPH 121, MPH 122, and MPH 122-2 recycler/stabilizers. When a union fails or leaks, fluid pressure integrity is compromised — replacing it promptly with part number 05541721 restores proper system function and keeps the machine working at full capacity.
Key Features
- Genuine OEM Fluid-Line Integrity — manufactured to Bomag's original connection specifications, ensuring correct thread form, sealing surface geometry, and material grade for the hydraulic or fluid circuit it serves
- Drop-In Connection Match — this union installs directly into the existing port without reworking fittings or adapting line ends, maintaining the original routing and torque specification
- Broad Cross-Family Coverage — fits BF 600 P-2 S 500, BF 600 P-3 S 500, and BF 800 P S500 pavers; BW 212 D-2 and BW 213 D single drum rollers; and MPH 121, MPH 122, and MPH 122-2 recycler/stabilizers
- Leak-Free Pressure Retention — a correctly seated union maintains system pressure across operating cycles; a worn or cross-threaded union risks fluid loss, pressure drop, and component damage downstream
A union is a threaded coupling that joins two sections of a fluid or hydraulic line, allowing them to be connected and disconnected without rotating the lines themselves. In Bomag pavers, rollers, and recycler/stabilizers, unions appear throughout hydraulic circuits, fuel systems, and cooling lines where serviceable connections are needed. When a union corrodes, cracks, or strips its threads, the affected circuit can leak fluid or lose pressure entirely — leading to erratic machine behavior, overheating, or hydraulic system failure. Replacing a damaged union promptly with the correct OEM component restores a tight, pressure-rated seal and returns the system to normal operation.
