The Husqvarna 590478602 Tank Cap Assembly is a genuine OEM component designed for the S36 dust extractor. This assembly provides a secure, airtight closure for the dust extractor's collection tank, ensuring the unit maintains proper suction and containment during operation. DHS Equipment supplies this part to help keep your equipment running at full efficiency.
Key Features
- OEM-Matched Seal Integrity — manufactured to Husqvarna's exact material and dimensional specs, ensuring the cap seats and seals the tank correctly every time.
- Direct-Fit Replacement — engineered to drop into the S36 tank opening without modification, using the original mounting interface for a secure, tool-free install.
- Confirmed S36 Compatibility — purpose-built for the Husqvarna S36 dust extractor; cross-reference part number 590478602 against your parts diagram before ordering.
- Sustained Suction Performance — a properly sealing tank cap is essential for maintaining negative pressure inside the collection tank; a cracked or ill-fitting cap reduces suction and allows dust to escape at the tank seam.
- Dust Containment Compliance — a correctly seated cap prevents uncontrolled dust release during tank handling and emptying, supporting on-site dust control requirements.
The tank cap assembly seals the top or access point of the dust extractor's collection tank, creating the closed system necessary for the motor to generate and sustain suction. When the cap is damaged, warped, or missing its sealing components, the extractor loses vacuum pressure, reducing its ability to capture airborne dust at the source. Replacing a worn cap assembly restores the airtight seal and brings the S36 back to its designed dust extraction performance.
