The Bomag 05722419 Square Ring is a genuine OEM sealing component designed for the BW 90 AD tandem roller, BW 75 AD-2 walk-behind roller, and a broad range of Bomag reversible vibratory plates including the 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 65/70 D, BPR 70/70 D, BPR 100/80 D, and BPH 80/65 S. As a genuine Bomag part, this square ring is manufactured to the exact material grade and cross-section geometry required by the original design, ensuring correct compression and seal integrity in service. This component drops into place without modification, restoring the sealing performance the machine was built to maintain.
Key Features
- OEM Sealing Material Grade — manufactured to Bomag's original compound and compression specification, so this square ring delivers the same fluid-barrier performance as the part it replaces
- Exact Cross-Section Geometry — the square profile seats flush in its groove, preventing the roll and extrusion failure that can occur with an incorrectly sized ring
- Broad Bomag Fitment — confirmed for the BW 90 AD tandem roller, BW 75 AD-2 walk-behind roller, and reversible vibratory plates including the BPR 75/60 D series, BPR 65/70 D, BPR 70/70 D, BPR 100/80 D, and BPH 80/65 S
- Fluid System Integrity — a correctly seated square ring keeps hydraulic or lubricating fluid where it belongs, preventing pressure loss and contamination that degrade compaction output
- Genuine Bomag Part — sourced directly from Bomag's OEM supply chain and carries part number 05722419 for confident, verified ordering
A square ring is a sealing element used in hydraulic circuits, fluid passages, and rotating or sliding interfaces to prevent fluid leakage between mating components. Unlike a round O-ring, its flat, square cross-section resists rolling and twisting under pressure, maintaining a stable seal over a wider range of operating conditions. When a square ring wears, hardens, or takes a compression set, the result is fluid leakage, loss of hydraulic pressure, or contamination ingress — any of which can cause erratic vibration output, overheating, or accelerated wear in the assemblies it seals.
