Key Features
- OEM Material Integrity — Manufactured to Husqvarna's exact compound and compression specifications for a hydraulic sealing ring, ensuring consistent performance under operating pressures.
- Drop-In Hydraulic Fit — Sized precisely for 1/2" hydraulic connections, this sealing ring seats correctly without modification, maintaining proper interface geometry at the port.
- Broad Cross-Machine Compatibility — A single part number covering PP325E, PP220, and PP455E power packs, WS440, WS440HF, WS460, WS462, and WS463 wall saws, DM406 core drill, CS2512 wire saw, and RC455 compactor.
- Leak Prevention at Critical Hydraulic Joints — A correctly seated sealing ring eliminates fluid loss at hydraulic connections, maintaining system pressure and protecting downstream components from contamination or starvation.
- Verified OEM Part Number — Cross-reference part number 531119185 against your machine's parts diagram to confirm the correct position before installation.
A sealing ring forms a pressure-tight barrier at hydraulic port connections and fittings, preventing fluid from escaping the circuit and stopping contaminants from entering. In hydraulic-driven equipment such as power packs, wall saws, and core drills, even a minor seal failure can cause gradual pressure loss, reduced cutting or drilling power, and fluid contamination that damages pumps and motors. Replacing a worn or damaged sealing ring promptly restores system integrity and protects the wider hydraulic circuit from secondary damage.
