The Bomag 05740191 O-Ring is a genuine OEM sealing component designed for Bomag tandem rollers, including the BW 80 AD-2, BW 80 ADS, BW 90 AD-2, BW 100 ADM-2, BW 131 ACW-2, and BW 131 AD-2. Sourced directly through Bomag's OEM supply chain, this O-Ring is manufactured to the exact material grade and dimensional tolerances required for proper sealing performance in these machines. Using the correct OEM part helps maintain system integrity and prevents the fluid leaks and pressure loss that a worn or improperly sized seal can cause.
Key Features
- OEM-Grade Sealing Material — Manufactured to Bomag's specified compound and durometer rating, ensuring the correct compression and chemical resistance for this application in tandem roller hydraulic and fluid systems.
- Exact-Dimension Replacement — Matches the original O-Ring's inner diameter, outer diameter, and cross-section precisely, seating correctly in its groove without modification.
- Broad Tandem Roller Coverage — Fits the BW 80 AD-2, BW 80 ADS, BW 90 AD-2, BW 100 ADM-2, BW 131 ACW-2, and BW 131 AD-2 tandem rollers.
- Leak Prevention — A correctly fitted O-Ring maintains system pressure and keeps fluid contained, preventing the gradual seal failure that leads to contamination, component wear, and unplanned service intervals.
- Genuine Bomag OEM Part — Part number 05740191 is an authentic Bomag component, giving you confidence in fitment accuracy when ordering a direct replacement for your tandem roller.
An O-Ring is a precisely dimensioned elastomeric seal that sits in a machined groove between two mating surfaces or along a shaft, creating a pressure-tight barrier against fluid or air leakage. In tandem rollers like the BW 80 AD-2 and BW 131 AD-2, O-Rings are found throughout hydraulic circuits, drum drive systems, and fluid passages where maintaining correct pressure is essential to smooth, consistent compaction performance. When an O-Ring deteriorates — through heat cycling, chemical exposure, or simple age — it loses its ability to seal, leading to fluid weeping, system pressure drop, and potential damage to surrounding components if left unaddressed.
