The Bomag 05012272 O-Ring is a genuine OEM sealing component designed for BW 177-series single drum rollers, including the BW 177 D-40, BW 177 DH-40, BW 177 PDH-40, BW 177 D-50, BW 177 DH-50, and BW 177 PDH-50. Sourced directly from Bomag, this O-Ring matches the original material grade and dimensional specification, ensuring a secure, leak-free seal in the exact location it was engineered for. Confirm your model against part number 05012272 before ordering to guarantee correct fitment across your BW 177 variant.
Key Features
- OEM Sealing Material — manufactured to Bomag's original compound and durometer specification, so the ring compresses and seals exactly as the system requires
- Exact Dimensional Fit — molded to the precise cross-section and inner diameter of the original, dropping into the groove without resizing or shimming
- Broad BW 177 Coverage — fits BW 177 D-40, BW 177 DH-40, BW 177 PDH-40, BW 177 D-50, BW 177 DH-50, and BW 177 PDH-50 single drum rollers
- Leak Prevention — a correctly seated O-Ring keeps hydraulic or fluid pressure contained, preventing contamination and pressure loss that can affect compaction output and machine response
- Genuine Bomag Part — supplied as an authentic OEM component under part number 05012272, with the traceability and consistency that keeps your roller operating to its designed specification
An O-Ring is a precision-molded loop of elastomeric material that forms a static or dynamic seal between two mating surfaces or within a port and fitting. In Bomag single drum rollers, O-Rings are used throughout hydraulic circuits, drive systems, and fluid reservoirs to prevent leaks and maintain pressure integrity. When an O-Ring wears, cracks, or takes a permanent set, the seal fails — fluid escapes, pressure drops, and the system can no longer deliver consistent performance, making prompt replacement essential to keeping the roller productive on site.
