The Bomag 05740271 O-Ring is a genuine OEM seal designed for Bomag BW 80 AD-2, BW 90 AD-2, BW 100 ADM-2, BW 80 ADS, and BW 90 AC-2 tandem rollers. Sourced directly from Bomag, this O-Ring matches the original material grade, durometer, and cross-section dimensions required for a proper seal in these machines. This replacement is the correct choice when addressing hydraulic or fluid leaks traced to a worn or damaged O-Ring on these tandem roller models.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Bomag's exact material and dimensional specifications, ensuring the seal compresses and seats correctly under pressure — critical for preventing hydraulic or fluid loss
- Drop-In Replacement — matches the original O-Ring profile and diameter, allowing this part to seat directly into the existing groove without modification
- Broad Tandem Roller Coverage — fits BW 80 AD-2, BW 90 AD-2, BW 100 ADM-2, BW 80 ADS, and BW 90 AC-2 tandem rollers, covering multiple configurations within the Bomag tandem roller lineup
- Leak Prevention — a degraded O-Ring allows fluid to bypass the seal, leading to pressure loss and potential system damage; replacing this component at first sign of seepage protects downstream components
- Part Number Confidence — ordering by part number 05740271 ensures you receive the exact Bomag-specified seal for your machine, eliminating guesswork during service
An O-Ring is a circular elastomeric seal installed in a machined groove between two mating surfaces or around a fitting. Its role is to block the passage of fluids or gases under pressure, maintaining system integrity in hydraulic circuits, fluid connections, and other pressurized assemblies throughout the machine. When an O-Ring ages, hardens, or becomes physically damaged, it loses its ability to form a complete seal — fluid begins to seep past the ring, pressure drops in the affected circuit, and surrounding components are exposed to contamination or dry running. Replacing a worn O-Ring promptly with the correct OEM part restores the seal and keeps the hydraulic or fluid system functioning as intended.
