Key Features
- OEM-Grade Seal Material — Manufactured to Husqvarna's exact rubber compound and compression specifications, ensuring the seals conform correctly to mating surfaces within the drill motor assembly.
- Complete Set for Full Service — Includes all rubber seals required for a thorough service interval, so all worn or compromised seals are replaced in a single procedure.
- Broad Core Drill Compatibility — Engineered to fit the DM280, DM406, DM430, DM700, DM540i, DM540iKIT, DM230, and DM400 concrete core drills, covering a wide range of Husqvarna's professional DM-series lineup.
- Restored Fluid Integrity — Properly seated seals prevent hydraulic fluid or coolant ingress and egress, protecting internal drill motor components from contamination and premature wear.
- Leak Prevention at the Source — Worn or cracked seals are a leading cause of fluid loss and motor damage in core drills; replacing them with a correctly specced OEM set addresses the failure at its root.
A rubber seal set provides the critical barrier between moving and stationary components inside a concrete core drill motor, preventing fluid leakage and keeping contaminants out of precision internal parts. When seals degrade — due to heat cycles, abrasive slurry, or extended service hours — fluid begins to bypass the sealing surfaces, leading to loss of operating pressure, overheating, and accelerated wear on the motor's internal components. Replacing the full set with genuine OEM seals restores the original sealing performance and protects the integrity of the entire drill motor assembly.
