The Bomag 05585066 O-Ring is a genuine OEM sealing component designed for Bomag single drum rollers across the BW 124 and C-series lines. This O-Ring delivers the precise dimensional fit required to maintain system integrity on models including the BW 124 DH-3, BW 124 PDH-3, BW 124 DH-4, BW 124 PDH, BW 124 DH-40, BW 124 PDH-40, C 815 C, and C815D. As a genuine Bomag part, it is manufactured to the same material and tolerance specifications as the original, ensuring a proper seal without rework or adaptation. Sourced directly through DHS Equipment, part number 05585066 is the correct replacement when servicing these single drum rollers.
Key Features
- OEM Material Integrity — Manufactured from the same elastomer compound as the original, delivering the compression and chemical resistance required for this sealing application.
- Drop-In Sealing Fit — Dimensionally identical to the factory O-Ring, seating correctly in its groove without stretching, trimming, or modification.
- Broad BW 124 and C-Series Coverage — Fits BW 124 DH-3, BW 124 PDH-3, BW 124 DH-4, BW 124 PDH-40, C 815 C, C815D, and additional BW 124 variants — a single part number covering the full range.
- Leak Prevention — A properly seated O-Ring keeps hydraulic or fluid circuits sealed under operating pressure; a worn or cracked ring leads to fluid loss, contamination, and loss of system pressure.
- Genuine Bomag OEM Part — Supplied as an authentic Bomag replacement, backed by the manufacturer's part number 05585066 for confident, verified ordering.
An O-Ring is a molded elastomeric seal used to close the gap between two mating surfaces or components, preventing the escape of hydraulic fluid, oil, or coolant under pressure. In single drum rollers like the BW 124 series, O-Rings appear throughout the hydraulic system, engine assembly, and fluid circuits, where maintaining a leak-free connection is critical to consistent compaction force and safe operation. When an O-Ring hardens, cracks, or deforms with age and heat cycles, it loses its sealing ability — resulting in fluid leaks, pressure drop, and potential damage to surrounding components if left unaddressed.
