The Bomag 06245009 Square Ring is a genuine OEM sealing component designed for Bomag BW 177-series and BW 179-series single drum rollers, BW 145-series single drum rollers, and the BC 601 RB refuse/landfill compactor. As a direct OEM replacement, this square ring is manufactured to Bomag's original specifications, ensuring a correct, leak-free fit without the need for modification. Sourced directly from Bomag, part number 06245009 is the same component installed at the factory, giving you confidence in both fitment and sealing performance across all covered machine variants.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Bomag's original material and dimensional specifications, delivering the compression and chemical resistance required for dependable hydraulic or fluid sealing in demanding compaction equipment
- Direct Drop-In Replacement — this square ring seats exactly as the original, with no trimming, adaptation, or reworking of the housing needed to achieve a proper seal
- Broad Fitment Coverage — fits BW 145, BW 177, and BW 179 single drum rollers across multiple generation variants, as well as the BC 601 RB refuse/landfill compactor, covering a wide range of Bomag heavy equipment in the field
- Leak Prevention Where It Counts — a failed or worn square ring allows fluid bypass, leading to pressure loss, component wear, and unplanned repairs; replacing it promptly restores system integrity and keeps compaction performance on spec
- Verified Part Number Fitment — ordering by Bomag part number 06245009 ensures you receive the exact ring profile, cross-section, and material grade specified for these machines, eliminating guesswork at the repair bench
A square ring is a sealing element used in hydraulic and fluid systems to prevent leakage between mating surfaces or around moving components. Unlike a standard O-ring, a square ring's flat-sided profile provides a larger sealing contact area, making it particularly effective in dynamic or high-pressure applications where extrusion resistance matters. When a square ring wears, hardens, or becomes damaged, it can no longer maintain a proper seal — resulting in fluid leaks, reduced hydraulic pressure, and accelerated wear on surrounding components that depend on proper lubrication or pressurization.
