The Husqvarna 590476201 Tank Cap Assembly is a genuine OEM component designed for the S13 dust extractor. This assembly ensures a correct, airtight seal on the tank, maintaining the suction performance and containment integrity the machine depends on. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- OEM-Engineered Seal Integrity — manufactured to Husqvarna's exact material and compression specifications, ensuring the cap seats correctly and holds a consistent seal under operating conditions.
- Direct-Fit Replacement — this assembly installs directly onto the S13 tank opening using the original mounting configuration, requiring no rework or adjustment.
- Built for the S13 Dust Extractor — engineered specifically for the S13, so you can cross-reference part number 590476201 against your parts diagram with confidence before ordering.
- Maintains Dust Containment Performance — a properly functioning tank cap is critical to maintaining negative pressure inside the unit; a worn or damaged cap allows air ingress that directly reduces suction efficiency.
- Dust Exposure Compliance — a correctly sealing tank cap prevents the escape of collected dust during operation and emptying, supporting safe handling of silica and other hazardous particulates on the worksite.
The tank cap assembly serves as the primary closure for the dust extractor's collection tank, forming an airtight seal that is essential to maintaining consistent suction pressure throughout the unit. When the cap degrades or no longer seats properly, air leaks into the system, reducing extraction efficiency and potentially allowing collected dust to escape during use or when servicing the tank. Replacing the Tank Cap Assembly with a genuine OEM part restores the intended seal and keeps the S13 operating as designed.
