The Bomag 05821000 Safety Cartridge is a genuine OEM component designed for BC-series refuse/landfill compactors, the BC 473 EB-3 soil compactor, and MPH 121 and MPH 122 recyclers/stabilizers. Sourced directly from Bomag, this safety cartridge meets the exact specifications of the original part it replaces, delivering the fitment accuracy that operators and fleet managers depend on. Compatible across a broad range of BC-series models — including the BC 570 RB, BC 671 RB, BC 771 RB, BC 972 RB, and BC 1172 RB families — this part covers multiple generations and variants of these heavy-duty machines.
Key Features
- Genuine OEM Pressure Integrity — manufactured to Bomag's original hydraulic system specifications, ensuring the safety cartridge activates and holds at the correct pressure threshold for this class of machine.
- Direct-Fit Replacement — engineered to match the original valve port geometry and thread specification, allowing straightforward installation without machining or adaptation.
- Broad Fleet Coverage — fits BC-series refuse/landfill compactors including BC 570 RB, BC 671 RB, BC 671 RS, BC 771 RB, BC 771 RS, BC 972 RB, BC 1172 RB, and their generation variants, plus the BC 473 RB-3, BC 473 EB-3, and MPH 121 and MPH 122 recyclers/stabilizers.
- Hydraulic System Protection — a correctly functioning safety cartridge guards the hydraulic circuit against dangerous overpressure events; a failed or bypassed cartridge can lead to hose rupture, component damage, or uncontrolled machine movement.
- Safety-Critical Compliance — as a pressure-relief and safety valve component, using the correct OEM-spec cartridge ensures the hydraulic system responds as designed under overload conditions, protecting both the operator and the machine.
A safety cartridge is a hydraulic valve component that limits system pressure by opening a relief path when pressure exceeds a set threshold, preventing damage to pumps, motors, cylinders, and hoses. On heavy refuse/landfill compactors and recycler/stabilizer machines, the hydraulic system operates under demanding loads, making an accurate, reliable pressure-relief point essential to safe machine operation. When the safety cartridge wears, clogs, or fails to seat correctly, the hydraulic circuit loses its overpressure protection — risking sudden component failure, fluid leaks, or loss of machine control at the worst possible moment.
