Key Features
- OEM-Grade Seal Material — manufactured to Husqvarna's original compression and material specifications, ensuring the ring seats and performs exactly as the factory-installed component did.
- Direct Drop-In Replacement — engineered to match the original seating groove dimensions on the DM280, DM340, and DMS280, so this sealing ring installs without modification or adaptation to existing hardware.
- Broad Core Drill Fitment — compatible with the DM280 and DM340 drill motors and the DMS280 drill motor system, covering a wide range of professional concrete core drilling setups.
- Leak Prevention and Pressure Integrity — a properly seated sealing ring keeps internal fluids or pressurized air contained within the drill assembly, preventing contamination and maintaining consistent drilling performance.
- Genuine Husqvarna OEM Part — backed by Husqvarna's OEM quality assurance, this is the same component used in new machines — not an approximation or generic substitute.
A sealing ring creates a fluid-tight or pressure-tight barrier between mating surfaces or rotating components within the drill motor assembly. In concrete core drills like the DM280, DM340, and DMS280, maintaining that barrier is critical — a worn or damaged sealing ring allows coolant, water, or lubrication to migrate where it should not, which can lead to accelerated internal wear, loss of drilling efficiency, and potential damage to surrounding components. Replacing a compromised sealing ring promptly restores the integrity of the assembly and protects the broader investment in the drill motor system.
