The Bomag 05719639 O-Ring is a genuine OEM sealing component designed for BW 172 D-2 and BW 142 D-2 single drum rollers, as well as the BW 135 AD tandem roller. Sourced directly from Bomag, this O-Ring matches the original material grade and dimensional profile for a proper seal every time. This part installs directly in place of the worn original, with no guesswork on sizing or fitment. Confirmed compatible with part number 05719639, it is the correct choice for keeping hydraulic or fluid systems sealed and operating at spec on these machines.
Key Features
- OEM-Grade Elastomer Construction — manufactured to Bomag's original compound and durometer specification, delivering the compression and chemical resistance the application demands
- Exact Dimensional Match — cross-section diameter and inner diameter match the original, so this O-Ring seats fully and seals correctly without shimming or adjustment
- Confirmed Fitment — genuine OEM replacement for BW 172 D-2 and BW 142 D-2 single drum rollers and the BW 135 AD tandem roller
- Leak-Free Sealing Performance — a correctly installed O-Ring prevents fluid loss at joints and fittings; a cracked or extruded seal leads to pressure drop, contamination, and accelerated wear on surrounding components
- Direct OEM Source — genuine Bomag part number 05719639, not an approximation, ensuring traceability and consistent quality across service intervals
An O-Ring is a loop-shaped seal fitted into a groove between two mating surfaces or around a shaft or fitting. Its job is to block the passage of fluid or air under pressure by compressing against both surfaces when the joint is assembled. On rollers like the BW 172 D-2, BW 142 D-2, and BW 135 AD, O-Rings are used throughout the hydraulic system, drive components, and fluid circuits to maintain pressure and prevent contamination. When an O-Ring ages, hardens, or gets cut during assembly, the resulting leak can starve a circuit of pressure, introduce contaminants, or cause fluid loss that damages more expensive downstream components — making timely O-Ring replacement one of the most cost-effective service tasks on any machine.
