The Bomag 05719631 O-Ring is a genuine OEM sealing component designed for BW 172 D-2 and BW 142 D-2 single drum rollers and the BW 135 AD tandem roller. Sourced directly from Bomag, this O-Ring is manufactured to the exact material grade and dimensional tolerances of the original part. Verified fitment across these machines means this seal drops into place with the same profile and compression characteristics as the part it replaces.
Key Features
- OEM Material Specification — manufactured to Bomag's exact compound and durometer rating, ensuring the correct compression set and sealing performance for this application
- Exact-Profile Replacement — matches the original cross-section and diameter precisely, seating correctly in the groove without trimming or adjustment
- Confirmed Fitment — compatible with the BW 172 D-2 and BW 142 D-2 single drum rollers and the BW 135 AD tandem roller, as specified by Bomag's OEM parts catalog
- Leak-Free Sealing — a properly installed O-Ring prevents fluid loss at the sealed joint, maintaining hydraulic or fluid system pressure and protecting surrounding components from contamination
- Genuine Bomag Part — supplied under part number 05719631 as an authorized OEM component, backed by Bomag's parts program
An O-Ring is a circular elastomeric seal fitted into a machined groove between two mating surfaces or around a shaft to prevent fluid or air from passing through the joint. In roller applications, O-Rings are used throughout hydraulic circuits, fluid reservoirs, and connection points where maintaining a leak-free seal is critical to consistent machine output and component longevity. When an O-Ring hardens, cracks, or deforms, the seal fails — leading to fluid loss, pressure drop, and potential damage to adjacent components if left unaddressed.
