The Bomag 06550090 O-Ring is a genuine OEM sealing component designed for Bomag tandem rollers, including the BW 141 AD-4, BW 141 AD-4 AM, BW 151 AD-4, BW 151 AD-4 AM, BW 151 AC-4, BW 151 AC-4 AM, BW 154 AD-4, BW 154 AD-4 AM, and BW 161 AC-4. Sourced directly from Bomag, this O-Ring is manufactured to the exact material grade and dimensional tolerances of the original, ensuring a dependable seal in the system it serves. Confirm your model against the fitment list and order part number 06550090 with confidence.
Key Features
- OEM-Grade Elastomer Construction — manufactured to Bomag's exact compound specification, delivering the compression resistance and chemical compatibility required for a lasting hydraulic or fluid seal
- Exact-Fit Replacement — dimensionally identical to the original, this O-Ring seats correctly in its groove without adjustment, maintaining proper sealing pressure from the moment it is installed
- Broad Tandem Roller Coverage — fits the BW 141 AD-4, BW 151 AD-4, BW 151 AC-4, BW 154 AD-4, BW 161 AC-4, and their AM variants, covering a wide range of Bomag tandem roller configurations
- Leak Prevention Where It Counts — a correctly seated O-Ring keeps fluid circuits pressurized and contaminant-free; a worn or extruded seal leads to fluid loss, pressure drop, and accelerated wear of surrounding components
- Genuine Bomag Part — part number 06550090 is an authentic Bomag component, traceable to the OEM parts catalog for the machines listed
An O-Ring is a precision-molded elastomeric seal used to prevent fluid or air from passing between two mating surfaces — typically at fittings, ports, or housing joints within hydraulic, lubrication, or cooling circuits. When the O-Ring is in good condition, it maintains a reliable barrier that keeps system pressure stable and prevents contamination from entering sensitive components. As the ring ages, it can harden, crack, or deform under compression, causing leaks that reduce system efficiency and, if left unaddressed, lead to more extensive damage to the surrounding assembly.
