The Bomag 05719638 O-Ring is a genuine OEM sealing component designed for Bomag 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, durometer, and dimensional profile specified for these machines. This part installs as a direct replacement with no fitment issues, restoring a proper fluid-tight seal in the circuit or assembly it serves. If you are cross-referencing by part number, confirm against part number 05719638 to ensure an exact match for your machine.
Key Features
- OEM Material Specification — Manufactured to Bomag's exact compound and durometer rating, ensuring the correct compression set and long-term sealing performance for this application.
- Exact Dimensional Fit — Matches the original cross-section and inner diameter precisely, so this O-Ring seats correctly in its groove without distortion or gap.
- Verified Roller Fitment — Confirmed for BW 172 D-2 and BW 142 D-2 single drum rollers and the BW 135 AD tandem roller.
- Leak Prevention — A properly seated O-Ring keeps hydraulic or lubrication circuits sealed, preventing fluid loss that can lead to pressure drop, overheating, or component damage.
- Genuine Bomag OEM Part — Supplied as an authentic Bomag replacement, so you can order with confidence that it meets the original design intent for your machine.
An O-Ring is a precision-molded loop of elastomeric material that creates a fluid-tight seal between two mating surfaces — typically in hydraulic, lubrication, or cooling circuits. In a compactor roller, these seals are found throughout the drivetrain, drum, and hydraulic system, where even a small leak can cause a drop in system pressure, fluid contamination, or accelerated wear on adjacent components. When an O-Ring hardens, cracks, or takes a permanent set, it loses its ability to maintain that seal, and replacing it promptly with a correctly specified part prevents larger, more costly failures downstream.
