The Husqvarna 593963906 Rubber Seal Set is a genuine OEM component designed for Husqvarna concrete core drill motors, including the DM230, DM280, DM400, DM406, DM430, DM540i, DM540iKIT, and DM700. This seal set delivers an exact fit to the original design specifications, ensuring proper sealing across the drill motor assembly. DHS Equipment supplies this part to help keep your core drilling equipment running at full capacity.
Key Features
- OEM-Grade Seal Material — Manufactured to Husqvarna's original rubber compound and compression specifications, maintaining consistent sealing integrity under the pressure and heat cycles typical of core drilling operation.
- Direct Drop-In Replacement — Engineered to match the original seal profiles exactly, so this set installs into the drill motor housing without rework or modification to mating surfaces.
- Broad Core Drill Compatibility — Fits a wide range of Husqvarna DM-series concrete core drills, including the DM230, DM280, DM400, DM406, DM430, DM540i, DM540iKIT, and DM700.
- Leak Prevention — Properly seated seals prevent coolant and lubricant migration within the drill motor, protecting internal components from contamination and premature wear.
- Fluid Containment Compliance — Maintaining effective seals on a water-cooled core drill is essential for safe, controlled operation on-site; worn or failed seals can lead to uncontrolled fluid ingress or egress that affects both performance and operator safety.
A rubber seal set provides the critical fluid and pressure barriers within a core drill motor assembly. These seals prevent water, coolant, and lubricants from migrating between internal chambers or escaping to the exterior, which is essential for protecting the motor's moving parts during wet-core drilling. When seals degrade or fail, the drill motor becomes vulnerable to coolant contamination and lubrication loss — conditions that accelerate internal wear, cause overheating, and can result in motor failure if not addressed promptly.
