The Husqvarna 593963904 Rubber Seal Set is a genuine OEM component designed for Husqvarna concrete core drill motors, including the DM700, DM280, DM406, DM540i, DM540iKIT, DM430, DM230, and DM400. As a factory-sourced seal set, this component is manufactured to Husqvarna's exact material and dimensional specifications, ensuring a proper fit and full sealing performance from the moment it is installed. Cross-reference part number 593963904 against your parts diagram to confirm compatibility with your specific drill motor before ordering. DHS Equipment supplies this part to help keep your core drilling equipment running at full capacity.
Key Features
- OEM-Grade Rubber Compound — Manufactured from Husqvarna-specified rubber materials that resist hydraulic fluid, heat, and compression set — critical properties for a seal set operating inside a working drill motor.
- Exact-Match Sealing Profile — Each seal in the set is formed to the precise cross-section and durometer required for the DM-series motor bores, ensuring full contact and no bypass leakage upon installation.
- Broad DM-Series Compatibility — A single seal set that spans the DM230, DM280, DM400, DM406, DM430, DM540i, DM540iKIT, and DM700 concrete core drill motors, covering a wide range of Husqvarna's professional drill motor lineup.
- Restored Motor Integrity — Worn or damaged seals allow fluid or air ingestion that degrades drilling torque and motor response. Replacing with this set restores the motor's designed operating pressure and consistent power delivery.
- Safe Fluid Containment — Properly seated seals prevent internal fluid migration that can contaminate motor windings or hydraulic circuits, protecting both the operator and connected equipment from uncontrolled fluid exposure.
A rubber seal set forms the critical fluid and pressure barriers inside a core drill motor. These seals prevent internal leakage between chambers and keep contaminants from entering precision-machined surfaces. When seals degrade — through heat cycling, age, or abrasive slurry ingestion common in core drilling environments — the motor loses pressure integrity, resulting in reduced torque output, erratic speed control, and potential internal damage to the motor housing or spindle. Replacing a worn seal set with the correct OEM components restores the motor's designed pressure boundaries and protects the surrounding mechanical assembly from secondary wear.
