When it's time to replace a worn or damaged loop ring, choosing an authentic Bomag part number 05712932 keeps the hydraulic or mechanical circuit operating as originally engineered.
Key Features
- Genuine OEM Construction — manufactured to Bomag's original material and dimensional standards, delivering the same sealing geometry and tensile integrity as the part it replaces
- Direct-Fit Replacement — matches the original mounting profile and ring diameter, dropping into place without rework or adaptation on all listed machines
- Wide Fitment Coverage — compatible with BW 100, BW 120, BW 125, BW 135, BW 138, BW 141, BW 151, BW 154, and BW 177 series machines, including tandem rollers, single drum rollers, and the MPH 122 recycler/stabilizer
- Circuit Integrity Maintained — a correctly seated loop ring holds the hydraulic or mechanical connection under operating pressure; a worn or broken ring can cause fluid loss, loss of drive response, or system pressure drop
- Verified Part Number — order with confidence using Bomag part number 05712932, matched precisely to the machines listed in Bomag's own service catalog
A loop ring is a retaining or sealing ring used to secure a hydraulic hose fitting, mechanical coupling, or fluid-circuit connection within the machine's drive or auxiliary system. It holds the mating components together under vibration and operating load, preventing movement or separation at the joint. When a loop ring cracks, deforms, or loses its retention force, the connection it secures can weaken or fail, leading to fluid leaks, loss of hydraulic pressure, or mechanical play that affects the machine's compaction performance and response.
