The Bomag 05741431 O-Ring is a genuine OEM seal designed for Bomag BW 100, BW 120, BW 125, and BW 131 tandem rollers across the -4 and -5 generation variants. As an authentic Bomag component, this O-Ring is produced to the same material and dimensional specifications as the original, ensuring a correct seal every time. This part fits AC and AD drum configurations including the BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, BW 120 AC-4, BW 125 AD-4, BW 125 AC-4, BW120AD 4, BW 100 AD-5, BW 100 AC-5, BW 120 AD-5, BW 120 AC-5, and BW 131 AD-5. Sourcing genuine OEM means you get the right part the first time, with no guesswork on fitment.
Key Features
- Genuine OEM Sealing Material — manufactured to Bomag's original compound and durometer specifications, delivering the compression resistance and chemical compatibility this application demands
- Drop-In Replacement — matches the original cross-section and diameter exactly, seating into the groove without rework or adaptation
- Broad Tandem Roller Coverage — fits BW 100, BW 120, BW 125, and BW 131 tandem rollers across both the -4 and -5 generations, including AC and AD drum variants
- Leak-Free System Integrity — a correctly seated O-Ring prevents fluid loss and contamination ingress, keeping hydraulic or fluid-circuit pressures stable during compaction operation
- Genuine Bomag Part — supplied as an authentic OEM component with the correct part number 05741431, so you can verify the part against your machine's service documentation with confidence
An O-Ring is a molded elastomeric seal that fits into a machined groove to create a pressure-tight or fluid-tight barrier between mating components. In tandem rollers like the BW 100 and BW 120 series, O-Rings appear throughout hydraulic circuits, drum drive assemblies, and fluid reservoirs, where they prevent leaks and stop contaminants from entering sensitive systems. When an O-Ring degrades — through compression set, chemical swelling, or physical damage — it loses its ability to seal, leading to fluid leaks, pressure drop, and potential damage to surrounding components.
