The Husqvarna 502496504 O-Ring is a genuine OEM sealing component designed for DM280, DM340, DMS280, DM540i, DM540iKIT, and DM200 concrete core drills. As a direct Husqvarna OEM part, this O-Ring is manufactured to the exact material grade and dimensional specification required for a proper seal in these machines. Correct fitment matters with sealing components — cross-reference part number 502496504 against your parts diagram before ordering to confirm your application. DHS Equipment supplies this part to help keep your core drill operating at full capacity.
Key Features
- OEM Elastomer Specification — manufactured to Husqvarna's exact material compound and compression tolerances, ensuring the seal performs under the pressures and temperatures typical of core drilling operation.
- Drop-In Sealing Replacement — dimensioned to seat precisely in the original groove, requiring no trimming or adaptation during installation.
- Broad Core Drill Compatibility — fits DM280, DM340, DMS280, DM540i, DM540iKIT, and DM200 concrete core drills, covering a wide range of Husqvarna's drill motor lineup.
- Fluid and Pressure Integrity — a correctly seated O-Ring prevents coolant or hydraulic fluid from bypassing the seal, maintaining the pressure differential the drill motor depends on for consistent performance.
- Leak Prevention — a worn or degraded O-Ring allows fluid ingress or egress that can lead to rapid component wear; replacing it at the first sign of weeping or seeping protects surrounding assemblies.
An O-Ring forms a static or dynamic seal between two mating surfaces, compressing into its groove to block the passage of fluid, air, or debris. In concrete core drills like the DM280 and DM540i, O-Rings are critical to maintaining coolant flow paths and hydraulic circuit integrity — functions that directly affect drilling force and motor longevity. When an O-Ring deteriorates through heat cycling, chemical exposure, or mechanical wear, the resulting leak places stress on adjacent seals and components, making timely replacement essential to sustained drilling performance.
