The Bomag 05548508 O-Ring is a genuine OEM sealing component designed for the BW 120 AD tandem roller. Sourced directly from Bomag, this O-Ring meets the original material and dimensional specifications required for a proper seal in your machine. This part is the correct replacement when servicing fluid or hydraulic circuits on the BW 120 AD, ensuring the sealing surface performs as intended. Keeping the right O-Ring on hand is a straightforward way to stay ahead of leaks and maintain machine integrity during scheduled maintenance.
Key Features
- OEM-Grade Sealing Material — manufactured to Bomag's original compound and durometer specifications, ensuring the correct compression and chemical resistance for this application
- Direct-Fit Replacement — matched to the exact cross-section and inner diameter of the original, seating cleanly in the designed groove without rework or adaptation
- Confirmed Fitment — designed specifically for the BW 120 AD tandem roller; reference part number 05548508 when ordering to verify compatibility
- Leak Prevention — a properly seated O-Ring maintains fluid containment in hydraulic or fluid circuits, preventing pressure loss and contamination that can accelerate wear on surrounding components
- Genuine Bomag Part — supplied as an authentic OEM component, so you can be confident the material formulation and geometry match what was originally installed at the factory
An O-Ring is a circular elastomeric seal used to prevent fluid or air from passing between mating surfaces in hydraulic systems, fluid lines, and mechanical assemblies. On a tandem roller like the BW 120 AD, O-Rings appear throughout the hydraulic circuit and other pressurized systems, where they compress between two surfaces to form a leak-tight barrier. When an O-Ring degrades, cracks, or is damaged during disassembly, it can allow fluid to escape or contaminants to enter — leading to pressure drops, component wear, and eventual system failure if not addressed promptly.
