Key Features
- OEM-Grade Sealing Material — Manufactured to Husqvarna's exact material and dimensional specifications, delivering the compression and sealing integrity required for wall saw hydraulic and fluid systems.
- Drop-In Replacement Fit — Engineered to match the original port or passage geometry on compatible wall saws, seating correctly without additional tooling or adaptation.
- Broad Wall Saw Compatibility — Fits the WS440, WS440HF, WS442, and WS482 wall saws — confirm fitment by cross-referencing part number 579164701 against your parts diagram before ordering.
- Prevents Fluid Loss and Contamination — A correctly seated sealing plug blocks unwanted fluid escape and keeps contaminants out of internal passages, protecting downstream components and maintaining system pressure.
- Fluid System Integrity — Installing a genuine OEM plug eliminates the risk of an improperly sized or under-rated substitute working loose under operating pressure, which can lead to leaks or system pressure loss during cutting.
A sealing plug closes off hydraulic or fluid ports that are not in active use, preventing fluid from escaping and stopping debris or moisture from entering internal passages. In a wall saw system, maintaining sealed, pressurized fluid circuits is essential for consistent power delivery to the cutting head. When a sealing plug fails, cracks, or is missing, fluid loss and contamination can quickly compromise hydraulic performance and lead to costly secondary damage.
