The Husqvarna 590400401 Sealing Collar is a genuine OEM component designed for the S13, S26, HTCD10, and HTCD20 dust extractors and floor grinders. As a direct Husqvarna OEM replacement, this sealing collar is manufactured to the same specifications as the original part, ensuring a correct, secure fit every time.

DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- Genuine OEM Sealing Material — manufactured to Husqvarna's original compression and material specifications, ensuring the collar maintains a proper airtight seal over its service life.
- Direct-Fit Replacement — engineered to match the original mounting interface exactly, so this collar installs into the machine's housing without any modification or adaptation.
- Broad Equipment Compatibility — fits the S13, S26, HTCD10, and HTCD20, covering both S-line dust extractors and HTCD-series floor grinders in a single part number.
- Maintains Dust Containment Integrity — a correctly seated sealing collar prevents air and fine particulate bypass, keeping the machine's dust extraction efficiency at its intended level.
- Dust Extraction Safety Compliance — maintaining an intact seal is essential for silica and fine-dust control; replacing a worn collar helps the system operate within its designed extraction and filtration parameters.
The sealing collar forms a compression seal at a connection or housing joint within the dust extraction or grinding system. Its role is to prevent unfiltered air — and the fine particulate it carries — from bypassing the filtration path, which would reduce extraction efficiency and allow harmful dust to escape into the work environment. When the collar wears, deforms, or cracks, suction performance drops noticeably and dust containment is compromised, making timely replacement essential for both machine performance and operator safety.
