The Bomag 05585042 O-Ring is a genuine OEM seal designed for Bomag BW 124 and C 815 C single drum rollers across multiple generation variants. As an authentic Bomag part, this O-Ring is manufactured to the exact material grade and dimensional specification required to maintain a leak-free seal in its intended application. This part is confirmed to fit the BW 124 DH-3, BW 124 PDH-3, BW 124 DH-4, BW 124 PDH-4, BW 124 DH-5, BW 124 PDH-5, BW 124 DH-40, BW 124 PDH-40, C 815 C, and C815D single drum rollers, among other covered variants.
Key Features
- OEM Material Specification — manufactured to Bomag's precise compound and durometer rating, ensuring correct compression and sealing performance for this application
- Exact Dimensional Fit — matches the original cross-section diameter and inner diameter so this O-Ring seats correctly in its groove without adjustment
- Broad Single Drum Roller Coverage — fits BW 124 DH-3, BW 124 PDH-3, BW 124 DH-4, BW 124 PDH-5, BW 124 DH-40, C 815 C, C815D, and additional BW 124 series variants
- Leak Prevention — a correctly fitted O-Ring maintains fluid containment and system pressure; a degraded or mismatched seal causes fluid loss, contamination, and accelerated component wear
- Genuine Bomag Part — sourced directly from Bomag's OEM supply chain under part number 05585042, ensuring authenticity and traceability
An O-Ring is a circular elastomeric seal used to close the gap between two mating surfaces, preventing the passage of fluids or gases under pressure. In a single drum roller like the BW 124 series, O-Rings appear throughout hydraulic circuits, drive systems, and fluid reservoirs where a dependable, compression-loaded seal is essential to system integrity. When an O-Ring hardens, cracks, or deforms from age or heat exposure, it loses its ability to hold that seal — leading to fluid leaks, pressure loss, and potential damage to surrounding components if left unaddressed.
