The Bomag 05586221 Sealing Ring is a genuine OEM component designed for the MPH 121, MPH 122, and MPH 122-2 recycler/stabilizers. Sourced directly from Bomag, this sealing ring delivers an exact OEM fit with no guesswork on compatibility. It is the correct replacement for worn or damaged seals on these machines, ensuring the integrity of the assembly it protects is fully restored.
Key Features
- Genuine OEM Sealing Performance — manufactured to Bomag's exact material and dimensional specifications, ensuring proper compression and sealing force for this application
- Direct OEM Replacement — matches the original part number 05586221 exactly, dropping in place of the worn component without rework or adaptation
- Confirmed Fitment — compatible with the MPH 121, MPH 122, and MPH 122-2 recycler/stabilizers, covering this full line of Bomag soil improvement machines
- Leak Prevention — a properly seated sealing ring keeps fluids contained within their circuit, preventing contamination, pressure loss, and accelerated wear on surrounding components
- Long-Term Seal Integrity — genuine OEM material grade resists the heat cycles, vibration, and chemical exposure that cause aftermarket seals to harden or deform prematurely
A sealing ring creates a pressure-tight barrier between mating components, preventing fluid or air from escaping the assembly. On heavy recycler/stabilizer equipment like the MPH 122 series, these seals are exposed to significant mechanical stress, heat, and fluid pressure during operation. When a sealing ring wears, cracks, or deforms, the result is leakage that can lead to fluid loss, contamination of adjacent systems, and eventual damage to the components the seal was protecting — making timely replacement with a correct OEM part essential to keeping these machines working at full capacity.
