Key Features
- OEM-Grade Rubber Compound — Manufactured from the same rubber formulation specified by Husqvarna, delivering the correct compression rating and chemical resistance required for drill motor sealing applications.
- Complete Set for a Full Service — Includes all rubber seals needed for the service interval, allowing a thorough reseal of the drill motor without sourcing individual components separately.
- Broad DM-Series Compatibility — Fits DM230, DM280, DM400, DM406, DM430, DM540i, DM540iKIT, and DM700 concrete core drill motors, covering a wide span of the Husqvarna DM lineup.
- Leak Prevention and Motor Protection — Properly seated seals contain lubrication and block contaminant ingress; worn or degraded seals allow moisture and debris into the motor, accelerating internal wear and risking motor failure.
- Genuine OEM Part Number — Supplied under Husqvarna article number 593963905, eliminating guesswork and ensuring you receive the correct replacement every time.
The rubber seals within a core drill motor form the critical barrier between the motor's internal lubricated components and the harsh, water-saturated environment of diamond core drilling. They prevent coolant water and slurry from entering the motor housing while retaining the lubricants that keep internal moving parts protected. When these seals degrade — through heat cycling, chemical exposure, or age — leaks develop that can introduce contamination into the motor, leading to premature bearing wear and eventual motor failure. Replacing the full seal set with a genuine Husqvarna Rubber Seal Set restores that protective barrier and extends the service life of the drill motor.
