Husqvarna OEM Bottom Flap Assembly Kit for S13, S26 & S36 Vacuums — Part #590398601

Maintain a proper dust seal at the base of your Husqvarna vacuum with this genuine OEM bottom flap assembly kit. A damaged or worn bottom flap compromises the bag seal, allowing fine dust to bypass containment — this complete kit restores the original fit and function of your S-Series vacuum.

Restore Proper Dust Containment at the Base

The bottom flap is a critical sealing component on Husqvarna S-Series dust extractors. When it wears, cracks, or loses its shape, dust leaks past the bag seal and contaminates the work environment. Replacing it with a factory-spec assembly kit ensures your vacuum operates at full containment efficiency — essential for concrete prep, surface grinding, and dust-controlled jobsites.

Genuine OEM Assembly Kit — Complete Replacement

This is a full assembly kit — not just a single flap. All components needed for a complete bottom flap replacement are included, engineered to Husqvarna's original specifications for a direct, no-modification install on S13, S26, and S36 units.
