The Husqvarna 531073887 Radial Sealing is a genuine OEM component designed for the DM225 and DM225D concrete core drills. Sourced directly from Husqvarna, this part meets the exact material grade and dimensional tolerances specified for these machines. It is a direct replacement for the original, fitting the DM225 and DM225D without modification. DHS Equipment supplies this part to help keep your core drill performing at full capacity.
Key Features
- OEM-Grade Sealing Material — manufactured to Husqvarna's compression and material specifications, delivering the same performance as the original radial seal installed at the factory.
- Direct Drop-In Replacement — engineered to match the original seating geometry of the DM225 and DM225D, allowing straightforward installation against existing hardware.
- Confirmed Fitment — verified for the DM225 and DM225D concrete core drills; cross-reference 531073887 against your parts diagram before ordering.
- Restored Fluid Containment — a correctly functioning radial seal maintains the integrity of the drill's internal lubrication and hydraulic circuits, preventing fluid loss that leads to accelerated internal wear.
- Leak Prevention at the Shaft Interface — radial seals are a common wear point in core drill motors; replacing a degraded seal promptly prevents contamination ingress and protects surrounding components.
A radial sealing sits at the rotating shaft interface within the drill motor, creating a pressure-tight barrier that keeps lubricating oil in and contaminants out. In a concrete core drill like the DM225 and DM225D, this seal is subject to continuous rotational stress and exposure to water and slurry, causing it to harden or crack over time. When the seal fails, fluid leaks from the motor housing, lubrication is lost, and internal components begin to wear prematurely — making timely replacement essential to maintaining full drilling performance.
