DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- OEM Material Specification — Manufactured to Husqvarna's exact compound and durometer requirements, ensuring the correct compression set and long-term sealing performance for this specific application.
- Drop-In Sealing Fit — Dimensionally identical to the original, this O-Ring seats into the existing groove without modification, restoring a leak-free seal immediately upon installation.
- Broad Compatibility Across Drilling and Sawing Equipment — Fits the DM700 and DM650 concrete core drills as well as the WS8 and WS220 wall saws, making it a versatile service part across multiple Husqvarna Construction product families.
- Leak Prevention and System Integrity — A correctly seated O-Ring prevents fluid or pressure loss at critical joints, keeping hydraulic or water-feed systems operating within their designed parameters.
- Fluid and Contamination Resistance — Formulated to withstand exposure to water, hydraulic fluid, and the particulate-laden environments typical of concrete cutting and core drilling work.
An O-Ring creates a pressure-tight or fluid-tight seal between two mating surfaces, preventing leaks at joints, ports, and housings within the machine. In concrete core drills and wall saws, O-Rings are found throughout water-feed lines, hydraulic circuits, and motor housings where maintaining a reliable seal is critical to both performance and component protection. When an O-Ring degrades, flattens, or cracks, the resulting leak can cause pressure drop, water ingress into sensitive components, or hydraulic fluid loss — all of which compromise cutting performance and can lead to accelerated wear on surrounding parts.
