Key Features
- Genuine OEM Sealing Material — manufactured to Husqvarna's compound and durometer specifications, ensuring the correct compression and chemical resistance for hydraulic or fluid-system applications on demolition robots.
- Exact-Dimension Replacement — this O-Ring matches the original profile precisely, seating correctly in its groove without modification to maintain a leak-free interface.
- Broad DXR Family Fitment — confirmed compatible with the DXR250, DXR270, DXR300, and DXR310 remote-controlled demolition robots.
- Sealing Integrity Restored — a worn or damaged O-Ring allows fluid to bypass its intended circuit, leading to pressure loss or contamination; replacing it with this genuine component restores proper system containment.
- Fluid System Safety — maintaining a correctly seated O-Ring in hydraulic circuits prevents uncontrolled fluid release, protecting operators and keeping the machine's hydraulic pressure within safe operating parameters.
An O-Ring forms a static or dynamic seal between mating surfaces, blocking the passage of hydraulic fluid, lubricant, or coolant under pressure. On a demolition robot like the DXR series, these seals are critical to maintaining hydraulic circuit integrity across the tool carrier, drive system, and attachment interfaces. When an O-Ring degrades — through heat cycling, chemical exposure, or mechanical wear — it loses its ability to hold compression, resulting in fluid leaks, pressure drop, and potential damage to surrounding components. Replacing the failed seal promptly with the correct genuine OEM part restores the system to its designed operating condition.
