Key Features
- Genuine OEM Construction — manufactured to Bomag's original material and dimensional standards, ensuring the sealing surfaces and thread form match exactly what left the factory
- Direct-Fit Replacement — installs into the existing port or line connection without reworking fittings, threads, or adjacent hardware
- Broad Equipment Coverage — fits Bomag tandem rollers including the BW 120 AD, BW 141 AD-2, BW 144 AD-2, BW 151 AC-2, BW 151 AD-2, and BW 154 AD-2, the BW 177 D-3 single drum roller, BW 28 RH pneumatic tyred roller, and BM 1200/35 T4f and BM 1300/35 T4f cold milling machines
- Leak-Free System Integrity — a correctly sized and properly threaded union maintains a secure, pressure-tight connection; a worn or damaged union can cause fluid loss, pressure drop, and system contamination
- Verified Part Number — ordering part number 05541705 matches the Bomag OEM catalog reference, eliminating compatibility uncertainty on multi-machine fleets
A union is a threaded fitting that joins two sections of hydraulic or fluid line, allowing them to be connected and disconnected without disturbing the rest of the plumbing. It functions as a bridge between line segments, maintaining a sealed, pressure-rated pathway for fluid to flow through the system. When a union corrodes, strips, or develops a leak, fluid loss can compromise hydraulic pressure or cooling flow, leading to erratic machine performance or component overheating — making prompt replacement with the correct OEM part essential.
