The Husqvarna 522961601 O-Ring is a genuine OEM sealing component designed for the DXR140, DXR250, DXR270, and DXR300 demolition robots. Sourced directly from Husqvarna, this O-Ring delivers the exact material grade, compression profile, and dimensional tolerancing required to maintain a proper seal in demanding demolition environments. It is a direct replacement for the original component, confirming compatibility with the DXR series platform. DHS Equipment supplies this part to help keep your equipment running at full operational capacity.
Key Features
- OEM-Grade Elastomer Construction — manufactured to Husqvarna's material specification, ensuring the correct compression set and chemical resistance for hydraulic and mechanical sealing applications in demolition robots.
- Exact Dimensional Fit — matches the original groove geometry and cross-section of the DXR series, seating correctly without shimming, modification, or adjustment.
- DXR Series Compatibility — confirmed fitment for the DXR140, DXR250, DXR270, and DXR300 demolition robots, covering both mid-size and large-frame models in the DXR platform.
- Leak Prevention Under Load — a correctly seated O-Ring maintains system pressure integrity during heavy-duty breaking and demolition cycles, preventing fluid ingress or bypass that could compromise hydraulic performance.
- Genuine Husqvarna OEM Part — supplied under Husqvarna part number 522961601, cross-reference this number against your machine's parts diagram to confirm the correct application before ordering.
An O-Ring creates a static or dynamic pressure seal between mating components, preventing hydraulic fluid, lubricant, or contaminants from migrating across the joint. In a demolition robot like the DXR series, O-Rings are subjected to high-pressure hydraulic cycles, vibration, and exposure to concrete dust and debris — conditions that degrade the elastomer over time and cause the seal to lose its compression. A failed or worn O-Ring leads to fluid leakage, pressure loss, and potential ingress of contaminants that can damage adjacent hydraulic components. Replacing a compromised O-Ring with a correctly specified genuine OEM part restores the sealed interface and protects the broader hydraulic system.
