Key Features
- OEM-Grade Sealing Material — Manufactured to Husqvarna's material and compression specifications, ensuring the seal performs correctly under the wet, abrasive conditions typical of dust and slurry equipment operation.
- Drop-In Replacement Fit — Engineered to match the original profile and dimensions exactly, so this seal seats correctly without modification or adjustment during installation.
- Broad Model Compatibility — Fits the S13, S26, S36, T4000, T4000GP, D30, C5500, C5500B, PS30, HTCD10, and HTCD20, covering both dust extractors and floor grinder dust management systems.
- Prevents Contamination and Leakage — A correctly functioning seal keeps slurry, moisture, and fine particulate contained within the system, protecting internal components and maintaining suction integrity.
- Dust Containment Compliance — Using a genuine OEM seal ensures the equipment continues to perform within its intended dust containment rating, supporting compliance on jobsites with silica dust control requirements.
A seal in dust and slurry equipment forms a critical barrier between wet or particulate-laden airflow and the surrounding mechanical components. It maintains the pressure differential needed for effective suction and slurry containment, while preventing abrasive material from migrating into areas where it can accelerate wear. When a seal deteriorates or fails, suction performance drops, leaks may develop, and internal components become vulnerable to contamination — making timely replacement essential to keeping the equipment functioning as intended.
