Key Features
- OEM Material Specification — Manufactured to Husqvarna's exact compound and durometer spec, ensuring the correct compression set and sealing performance for hydraulic or fluid-circuit applications on demolition robots.
- Exact-Dimension Replacement — This O-Ring matches the original groove geometry and cross-section diameter, seating correctly without modification to mating components.
- Broad DXR Family Fitment — Compatible with DXR140, DXR145, DXR250, DXR270, DXR275, DXR300, DXR305, DXR310, and DXR315 demolition robots, covering a wide range of the DXR platform.
- Leak Prevention — A correctly seated O-Ring maintains fluid containment within the hydraulic circuit; a degraded or improperly sized ring leads to fluid seepage, pressure loss, and potential system failure.
- Hydraulic System Integrity — Maintaining proper seals throughout the hydraulic system is critical on demolition robots, where pressure loss can compromise tool force, responsiveness, and safe operation.
An O-Ring forms a pressure-tight seal between two mating surfaces or within a port, preventing hydraulic fluid or lubricant from escaping the circuit. On a demolition robot like the DXR series, the hydraulic system powers the arm movements and tool attachments, so even a minor seal failure can cause measurable pressure drop and reduced cutting or breaking force. When an O-Ring hardens, cracks, or loses its original profile from heat and chemical exposure, it can no longer maintain that seal, making timely replacement essential to sustained hydraulic performance.
