As an authentic Bomag part, this Union is manufactured to the same specifications as the original, ensuring a direct, compatible installation on the machines it was engineered to serve. Fitment includes the BW 124 DH-3, BW 124 PDH-3, BW 124 DH-4, BW 124 PDH, BW 124 DH-5, BW 124 PDH-5, BW 124 DH-40, BW 124 PDH-40, C 815 C, and C815D single drum rollers.

Key Features
- Genuine OEM Construction — manufactured by Bomag to the original connection specification, ensuring the Union seats and seals correctly within the machine's fluid system without improvisation or adaptation
- Direct-Fit Replacement — engineered to install in the same position and orientation as the original Union, with matching thread form and port sizing for a straightforward swap
- Broad Single Drum Roller Coverage — fits BW 124 DH-3, BW 124 PDH-3, BW 124 DH-4, BW 124 PDH-5, BW 124 DH-40, C 815 C, C815D, and additional BW 124 series variants across multiple generation suffixes
- Fluid System Integrity — a correctly functioning Union maintains leak-free connections in the machine's hydraulic or fluid circuit; a worn or damaged union can cause pressure loss, fluid leaks, and system contamination that compromise compaction performance
- Verified Part Number — ordering by Bomag part number 05553716 confirms you receive the exact component specified for your machine, eliminating guesswork when sourcing a replacement
A union is a threaded fitting used to join two sections of pipe or hose within a machine's fluid system, allowing the connection to be assembled and disassembled without rotating either line. On single drum rollers like the BW 124 series and C 815 C, unions appear in hydraulic and cooling circuits where serviceable connections are required. When a union corrodes, cracks, or develops thread damage, it can cause fluid leaks that reduce system pressure and lead to overheating or loss of hydraulic function — making timely replacement important to keeping the machine operating at full capacity.
