Key Features
- OEM-Grade Sealing Material — manufactured to Husqvarna's material and compression specifications, ensuring the seal performs under the hydraulic pressures and operating temperatures typical of heavy demolition work.
- Direct-Replacement Fit — this seal installs directly into the designated sealing cavity with no rework, maintaining the correct interface dimensions for a secure, leak-free connection.
- Broad DXR Demolition Robot Compatibility — confirmed fitment across the DXR250, DXR270, DXR275, DXR300, DXR305, DXR310, and DXR315 demolition robots, covering a wide range of Husqvarna's remote-controlled demolition platform.
- Hydraulic System Integrity — a correctly functioning seal prevents fluid loss and contamination ingress, keeping the hydraulic circuit pressurized and the robot's attachments operating at full force and precision.
- Fluid Containment and Environmental Compliance — maintaining an intact seal prevents hydraulic fluid leaks that could create slip hazards or environmental violations on the worksite.
A seal serves as the barrier between pressurized hydraulic fluid and the external environment — or between two internal hydraulic circuits — within the demolition robot's hydraulic system. When a seal is functioning correctly, it prevents fluid from escaping under pressure, maintains consistent system pressure, and keeps contaminants from entering sensitive components. When a seal deteriorates or fails, the result is hydraulic fluid loss, reduced attachment force, erratic machine response, and potential damage to surrounding components if the leak goes unaddressed.
