Key Features
- OEM Material Grade — manufactured to Husqvarna's exact compound and hardness specifications, delivering the compression and temperature resistance required in wall saw and drill feed hydraulic and fluid systems
- Exact-Profile Replacement — matches the original cross-section and diameter precisely, seating correctly in the groove without modification to the housing or mating surfaces
- Broad Fitment Across Two Equipment Families — compatible with the WS440, WS440HF, WS442, WS460, WS462, WS463, WS482, and WS482HF wall saws, plus the AD10 automatic drill feed
- Maintains Fluid and Hydraulic Integrity — a correctly seated O-Ring prevents fluid bypass and pressure loss, keeping the hydraulic circuit or coolant path operating within specification
- Genuine Husqvarna OEM Component — sourced directly from Husqvarna's construction equipment parts program, ensuring the part meets the same standards as the original installed unit
An O-Ring is a loop-shaped seal that sits in a machined groove between two mating surfaces or components, creating a pressure-tight barrier against fluid, hydraulic oil, or coolant leakage. In wall saws and automatic drill feeds, O-Rings are used throughout the hydraulic and water management circuits where maintaining consistent pressure and preventing contamination are critical to smooth, controlled cutting and drilling operation. When an O-Ring becomes worn, cracked, or compressed beyond its service limit, it loses its sealing ability — leading to fluid leaks, pressure drop, and potential damage to surrounding components if left unaddressed.
