The Bomag 05722258 Square Ring is a genuine OEM sealing component designed for a wide range of Bomag tandem rollers, walk-behind / light rollers, and reversible vibratory plates. Sourced directly from Bomag, this square ring delivers the exact material grade, dimensional tolerancing, and compression profile specified for the original application. It is confirmed to fit models including the BW 90 AD tandem roller, BW 65, BW 62 H, BW 75 AD-2, and BW 75 S-2 walk-behind / light rollers, as well as reversible vibratory plates including the BPR 50/52 D, BPR 65/52 D-3, BPR 65/70 D, BPR 70/70 D, BPR 75/60 D, BPR 75/60 D-2, BPR 75/60 D-3, BPR 75/60 HD-2, BPR 75/60 HD-3, BPR 100/80 D, BPH 80/65, and BPH 80/65 S. Ordering by part number 05722258 ensures you receive the correct seal geometry without guesswork or modification.
Key Features
- OEM Sealing Integrity — manufactured to Bomag's original compression and cross-section specification, ensuring consistent sealing pressure without distortion or creep over time
- Drop-In Replacement — matches the original groove dimensions exactly, seating fully on installation with no trimming or adaptation needed
- Broad Fitment Coverage — compatible with Bomag tandem rollers including the BW 90 AD, walk-behind / light rollers including the BW 65 and BW 75 AD-2, and reversible vibratory plates across the BPR 50, BPR 65, BPR 70, BPR 75, BPR 100, and BPH 80 series
- Leak Prevention — a correctly seated square ring maintains fluid containment in hydraulic or fuel circuits; a worn or flattened ring allows seepage that can lead to pressure loss and accelerated component wear
- Genuine Bomag Part — supplied as an authentic OEM component under part number 05722258, backed by Bomag's material and dimensional standards
A square ring is a four-sided profile sealing ring used in place of a traditional O-ring in specific groove geometries where a flatter contact face improves sealing stability under dynamic or static load. It creates a controlled compression seal between mating surfaces — typically within hydraulic circuits, fuel connections, or fluid reservoirs — preventing leaks that would otherwise cause system pressure loss or contamination. When a square ring degrades, flattens, or takes a permanent set, the seal breaks down, leading to visible fluid seepage, reduced hydraulic efficiency, and the risk of broader damage to surrounding components.
