The Bomag 05740031 O-Ring is a genuine OEM sealing component designed for Bomag tandem rollers, including the BW 80 AD-2, BW 80 ADS, BW 90 AC-2, BW 90 AD-2, BW 100 ADM-2, BW 131 ACW-2, and BW 131 AD-2. Sourced directly from Bomag, this O-Ring is manufactured to the exact material grade, diameter, and compression profile of the original part — ensuring a leak-free seal the first time, every time. When your tandem roller develops a fluid leak or shows signs of seal wear, replacing this component with the correct OEM part is the most direct path back to full working condition.
Key Features
- OEM-Grade Sealing Material — manufactured to Bomag's original compound specification, delivering the correct durometer hardness and chemical resistance for hydraulic and fluid system applications in tandem rollers
- Drop-In Replacement — matches the original cross-section and inner diameter exactly, seating into the groove without reworking surrounding components
- Broad Tandem Roller Coverage — fits the BW 80 AD-2, BW 80 ADS, BW 90 AC-2, BW 90 AD-2, BW 100 ADM-2, BW 131 ACW-2, and BW 131 AD-2 tandem rollers
- Leak Prevention — a correctly seated O-Ring maintains system pressure and keeps fluid where it belongs, protecting pumps, valves, and other downstream components from contamination or starvation
- Genuine Bomag Part — supplied as part number 05740031 under Bomag's OEM program, ensuring you receive the same component installed at the factory
An O-Ring is a precision sealing element that sits in a machined groove between two mating surfaces, creating a pressure-tight barrier that prevents fluid or air from escaping a system. In tandem rollers, O-Rings are used throughout hydraulic circuits, drive assemblies, and fluid reservoirs — anywhere two components meet and must stay sealed under pressure or temperature cycling. When an O-Ring ages, hardens, or is damaged during service, the seal fails and fluid begins to leak, leading to pressure loss, component wear, and eventual system failure. Replacing a worn O-Ring promptly with the correct OEM part restores system integrity and protects the broader assembly.
