The Bomag 05802546 O-Ring is a genuine OEM sealing component designed for BW 145-series and C 825 C single drum rollers. Sourced directly from Bomag, this O-Ring matches the original material grade, cross-section diameter, and durometer rating required for a proper seal in your machine's hydraulic or fluid system. This part is a direct replacement for worn or damaged O-Rings across the BW 145 D-3, BW 145 DH-3, BW 145 PDH-3, and C 825 C single drum rollers, among other compatible models in the BW 145 family. Keeping the correct sealing components in service protects surrounding components and maintains system integrity on the job.
Key Features
- Genuine OEM Sealing Material — manufactured to Bomag's original compound and hardness specifications, ensuring the correct compression set and fluid compatibility for this application
- Exact Cross-Section and Profile — matches the original O-Ring geometry precisely, seating correctly in the groove without modification or rework to the mating surfaces
- Broad BW 145-Series Coverage — fits BW 145 D-3, BW 145 DH-3, BW 145 PDH-3, BW 145 DH 40, BW 145 PDH 40, and C 825 C single drum rollers, consolidating sealing service across the family
- Leak Prevention at the Source — a correctly installed O-Ring maintains hydraulic or fluid pressure and prevents contamination ingress that can accelerate wear on pumps, valves, and cylinders
- Verified Part Number Traceability — ordering by Bomag part number 05802546 confirms you receive the correct seal for your specific machine, eliminating guesswork when sourcing service parts
An O-Ring is a precision-molded elastomeric seal that sits in a machined groove between two mating surfaces or around a moving shaft, creating a pressure-tight barrier that prevents fluid or air from escaping the system. In a single drum roller like the BW 145 series, O-Rings appear throughout the hydraulic drive circuit, steering system, and ancillary fluid connections, where they are subjected to constant pressure cycling and temperature variation. When an O-Ring hardens, cracks, or is cut during assembly, the resulting leak allows hydraulic fluid to escape or contaminants to enter, which can quickly lead to pressure loss, erratic machine behavior, and damage to more expensive downstream components.
