Key Features
- OEM-Grade Seal Material — Manufactured to Husqvarna's precise compound and durometer specifications, ensuring the correct compression set and chemical resistance for hydraulic and fluid system applications in demolition robots.
- Exact-Dimension Replacement — Matches the original profile and cross-section, so this O-Ring seats correctly in its groove without reworking or adjustment.
- Broad DXR Demolition Robot Fitment — Compatible with the DXR250, DXR270, DXR275, DXR300, DXR305, DXR310, and DXR315 demolition robots, covering the core of Husqvarna's remote-controlled demolition robot lineup.
- Leak-Free System Integrity — A correctly installed O-Ring maintains pressure and prevents fluid ingress or egress, protecting adjacent components and sustaining full hydraulic performance throughout the robot's operating cycle.
- Hydraulic System Safety — A failed or extruded O-Ring can cause uncontrolled fluid loss and pressure drop in hydraulic circuits; replacing it with the correct OEM component restores safe, controlled system operation.
An O-Ring creates a static or dynamic fluid seal between mating components in hydraulic circuits, fluid passages, and service joints. In a demolition robot like the DXR series, these seals are critical to maintaining hydraulic pressure, preventing contamination ingress, and ensuring that attachments and drive systems respond predictably under load. When an O-Ring degrades, flattens, or extrudes from its groove, the result is fluid leakage, pressure loss, and potential damage to surrounding components — making timely replacement with the correct OEM part essential to sustained machine performance.
