The Bomag 05711774 Sealing Ring is a genuine OEM component designed for BC-series refuse and landfill compactors and MPH-series recyclers/stabilizers, including the BC 670 RB, BC 671 RB, BC 671 RS, BC 672 RB, BC 571 RB, BC 772 RB, BC 772 RS, BC 972 RB, BC 1172 RB, MPH 121, and MPH 122. Sourced directly from Bomag, this sealing ring meets the same specifications as the original part installed at the factory. Its direct-fit design means it installs into the correct sealing interface without modification, restoring fluid containment and system integrity across all covered machines. For operators running heavy-duty landfill or stabilization equipment, using an authentic Bomag part number 05711774 is the straightforward way to maintain the seal performance these demanding machines depend on.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Bomag's exact material grade and dimensional tolerances, ensuring consistent compression and long-lasting fluid containment under the high-load conditions of landfill and stabilization work.
- Direct-Fit Replacement — engineered to match the original sealing ring profile, dropping into the correct bore or groove without rework or adjustment.
- Broad Machine Coverage — fits BC-series refuse/landfill compactors (BC 571 RB, BC 670 RB, BC 671 RB, BC 671 RS, BC 672 RB, BC 772 RB, BC 772 RS, BC 972 RB, BC 1172 RB) and MPH-series recyclers/stabilizers (MPH 121, MPH 122).
- Leak Prevention Under Pressure — a properly seated sealing ring keeps hydraulic or lubricating fluid where it belongs, protecting downstream components from contamination and pressure loss during continuous compaction or stabilization cycles.
- Authentic Bomag Part — verified under part number 05711774, eliminating fitment guesswork and ensuring you receive the exact component specified for these machines.
A sealing ring creates a pressure-tight barrier between mating components — such as hydraulic fittings, rotating shafts, or housing joints — preventing fluid from escaping and contaminants from entering the system. On heavy-duty refuse compactors and recyclers/stabilizers, where hydraulic systems operate under sustained high pressure and in abrasive environments, an intact seal is critical to maintaining actuator force, lubrication, and overall drivetrain health. When a sealing ring wears, hardens, or cracks, fluid leaks develop quickly, leading to pressure loss, component wear, and potential system damage if not addressed promptly.
