Key Features
- OEM-Grade Rubber Compound — Manufactured to Husqvarna's material specifications, ensuring the correct durometer and compression set resistance for sustained sealing performance in a core drill environment.
- Direct-Fit Replacement — Each seal in the set is dimensioned to match the original profiles in the drill motor housing, allowing straightforward installation without modification.
- Broad Core Drill Compatibility — Fits a wide range of Husqvarna DM-series concrete core drill motors, including the DM230, DM280, DM400, DM406, DM430, DM540i, DM540iKIT, and DM700.
- Restored Motor Integrity — A failed or deteriorated seal allows fluid ingress or pressure loss inside the motor assembly, directly affecting drilling torque and control. Replacing the set restores the motor's designed operating condition.
- Complete Set Supplied — Includes all required rubber seals for the service interval, so the repair can be completed in a single procedure without sourcing individual components separately.
The rubber seals within a core drill motor serve as critical barriers that maintain pressure boundaries and prevent fluid or debris ingress into precision internal components. When seals harden, crack, or deform through heat cycling and normal use, the motor can lose hydraulic efficiency, develop leaks, or become vulnerable to contamination that accelerates internal wear. Replacing the full Rubber Seal Set at the first sign of seeping or reduced performance restores the motor's operating integrity and protects the surrounding components from consequential damage.
