Key Features
- Genuine OEM Fluid-Tight Integrity — Manufactured to Husqvarna's original coupling specification, delivering the sealing performance and pressure tolerance the hydraulic or water circuit demands on a production floor saw.
- Exact-Match Connection — This Quick Coupling is engineered to mate directly with the mating ports on compatible FS-series floor saws, requiring no modification to the existing plumbing or fittings.
- Broad FS-Series Compatibility — Fits the FS400LV, FS413, FS513, FS520, FS524, FS600E, and FS309 floor saws, covering a wide range of Husqvarna's professional flat saw lineup.
- Restored Flow and Pressure Performance — A worn or damaged coupling can cause fluid leaks, pressure loss, or interrupted flow to critical systems; replacing it with this part restores consistent, uninterrupted operation.
- Leak-Prevention Safety — A properly sealed coupling prevents hydraulic or water fluid from escaping onto the cutting surface or operator area, supporting safe working conditions on the job.
A quick coupling is a connect-and-disconnect fitting used in the fluid circuit of a floor saw — typically in the water supply or hydraulic system — that allows hoses or lines to be joined or separated rapidly without tools. It maintains a leak-free seal under operating pressure, keeping fluid flowing to the blade cooling system or hydraulic drive where it is needed. When a coupling cracks, corrodes, or its internal seals fail, it can cause fluid loss, pressure drops, and potential system damage, making timely replacement essential to keeping the saw cutting accurately and safely.
