The Bomag 05740272 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 90 AC-2, and BW 100 ADM-2. Sourced directly from Bomag, this O-Ring matches the exact material grade, durometer, and dimensional tolerances of the original part. This sealing ring installs directly in place of the factory component, restoring fluid or pressure containment with no guesswork on fitment. For operators running any of these tandem roller models, part number 05740272 is the correct OEM specification replacement.
Key Features
- OEM-Grade Sealing Material — manufactured to Bomag's exact compound specification, ensuring the correct compression set and chemical resistance for this application
- Exact Dimensional Match — sized to the original cross-section and inner diameter, so this O-Ring seats correctly without stretching, pinching, or improvisation during installation
- Confirmed Tandem Roller Fitment — fits the BW 80 AD-2, BW 80 ADS, BW 90 AD-2, BW 90 AC-2, and BW 100 ADM-2 tandem rollers as a direct OEM replacement
- Leak Prevention Where It Counts — a properly seated O-Ring keeps hydraulic fluid, oil, or coolant contained; a degraded or incorrect ring leads to seeping joints, pressure loss, and accelerated component wear
- Genuine Bomag Part — supplied as an authentic OEM component, giving you confidence that the part number, material, and geometry match what left the factory
An O-Ring is a loop-shaped seal that sits in a machined groove between two mating surfaces, using compression to block the passage of fluid or gas. In tandem rollers like the BW-series machines, O-Rings appear throughout hydraulic circuits, drum drive assemblies, and fluid reservoirs, where maintaining a leak-free joint is critical to consistent compaction performance. When an O-Ring hardens, cracks, or takes a permanent set, it loses its ability to seal under pressure — allowing fluid to escape, contamination to enter, and downstream components to run dry or overheat.
