The Bomag 05548066 Double-Ended Union is a genuine OEM hydraulic fitting designed for Bomag BW 24 RH, BW 25 RH, BW 27 RH, BW 27 RH-4i, BW 27 RH-4i BC, BW 28 RH pneumatic tyred rollers, and the BW 177 PDH 5 single drum roller. Sourced directly from Bomag, this fitting matches the original specification for a clean, leak-free connection in the hydraulic or fluid circuit where it is installed. Whether you are restoring a machine to service or performing a scheduled fluid system repair, this double-ended union delivers the exact thread engagement and sealing geometry your roller requires.
Key Features
- Genuine OEM Hydraulic Fitting — manufactured to Bomag's original thread form and sealing specification, ensuring full pressure integrity at the union joint without improvised adaptations
- Direct Drop-In Connection — engineered to the same dimensional envelope as the factory-installed part, so this union threads in and seats correctly without reworking adjacent fittings or lines
- Broad Pneumatic Tyred and Single Drum Roller Coverage — fits BW 24 RH, BW 25 RH, BW 27 RH, BW 27 RH-4i, BW 27 RH-4i BC, BW 28 RH pneumatic tyred rollers, and the BW 177 PDH 5 single drum roller
- Leak-Free Fluid Circuit Integrity — a correctly seated double-ended union maintains system pressure and prevents fluid loss that can lead to erratic compaction performance or hydraulic component damage
- Verified Part Number Traceability — order by part number 05548066 to confirm you are receiving the correct Bomag union for your specific roller model, eliminating the risk of cross-threading or mismatched fittings
A double-ended union is a straight-through pipe or hose fitting that joins two fluid lines end-to-end within a machine's hydraulic or coolant circuit. It creates a secure, removable connection point that allows sections of plumbing to be separated for servicing without cutting or permanently altering the lines. When this fitting corrodes, cracks, or develops damaged threads, the resulting leak can deplete hydraulic fluid, drop system pressure, and compromise the compaction force or drive response of the roller — making prompt replacement with the correct OEM part essential to keeping fluid systems operating at design capacity.
