Key Features
- Precision-Molded OEM Sealing Dimensions — Manufactured to Husqvarna's exact 9.3 x 2.4 mm profile, ensuring correct compression and seal integrity in every application where this O-ring is specified.
- Drop-In Replacement — Matches the original groove dimensions and cross-section exactly, allowing this O-ring to seat correctly without modification to the housing or mating surfaces.
- Wide Cross-Family Fitment — Compatible with the DM406 core drill, FS-series floor saws, WS-series wall saws, the CS2512 wire saw, and the K3500 power cutter, making it a common service item across multiple Husqvarna Construction equipment families.
- Fluid and Pressure Containment — A correctly seated O-ring prevents coolant, hydraulic fluid, or water from bypassing sealing interfaces — loss of seal integrity at this point can cause fluid ingress, pressure drop, or internal contamination.
- Genuine Husqvarna OEM Quality — Sourced directly from Husqvarna, this component meets the same material grade and compression specifications as the original part fitted at the factory.
An O-ring is a circular elastomeric seal that sits in a precision-machined groove between two mating surfaces or components. Its job is to prevent fluid — whether water used for blade cooling, hydraulic oil, or cutting slurry — from leaking past the joint under operating pressure. When an O-ring ages, it can harden, crack, or take a permanent set, losing its ability to maintain compression and allowing fluid to bypass the seal. Replacing a worn O-ring promptly with a correctly dimensioned part like this one restores the pressure boundary and protects surrounding components from moisture or fluid damage.
