The Bomag 05585022 O-Ring is a genuine OEM sealing component designed for Bomag single drum rollers, including the BW 124 DH-3, BW 124 PDH-3, BW 124 DH-4, BW 124 PDH, BW 124 DH-40, BW 124 PDH-40, C 815 C, and C815D. Sourced directly from Bomag, this O-Ring matches the original specification for a drop-in fit with no guesswork on sizing or material grade. It is the correct choice when servicing these single drum rollers and keeping hydraulic or fluid circuits properly sealed. Order part number 05585022 from DHS Equipment with confidence in fitment accuracy.
Key Features
- OEM-Grade Sealing Material — manufactured to Bomag's original compound and dimensional specification, ensuring the correct compression set and resistance to hydraulic fluid, heat, and pressure cycles specific to these single drum rollers.
- Exact-Profile Replacement — this O-Ring matches the original cross-section and inner diameter exactly, seating cleanly in its groove without adjustment or trimming.
- Broad Single Drum Roller Coverage — fits the BW 124 DH-3, BW 124 PDH-3, BW 124 DH-4, BW 124 PDH, BW 124 DH-40, BW 124 PDH-40, BW124DH 4, BW124PDH 3, BW124PDH-40, C 815 C, and C815D single drum rollers.
- Leak-Free Circuit Integrity — a correctly seated O-Ring maintains fluid pressure and prevents contamination ingress; a worn or damaged one leads to fluid loss, pressure drop, and accelerated wear on surrounding components.
- Genuine Bomag OEM Part — part number 05585022 is an authorized Bomag replacement, backed by the same quality control as the original production component.
An O-Ring is a precision-molded loop of elastomeric material that creates a static or dynamic seal between two mating surfaces, preventing fluid or gas from escaping a pressurized circuit. In single drum rollers like the BW 124 and C 815 series, O-Rings appear throughout hydraulic drive systems, vibration circuits, and fluid connections, where maintaining a leak-free seal is critical to consistent compaction performance and component longevity. When an O-Ring degrades — through heat fatigue, chemical attack, or physical deformation — fluid leaks develop, pressure drops, and the surrounding assembly can suffer accelerated damage if the seal is not replaced promptly.
