The Husqvarna 576425101 O-Ring is a genuine OEM sealing component designed for the WS482HF, WS440HF, WS442, and WS482 wall saws. As a direct Husqvarna OEM part, it is manufactured to the exact material grade and dimensional tolerances required for proper sealing performance in these machines. This O-Ring is a direct-fit replacement for the original component, ensuring proper seating without modification. DHS Equipment supplies this part to help keep your wall saw operating at full capacity.
Key Features
- OEM-Grade Sealing Material — Manufactured to Husqvarna's exact compound and compression specifications, delivering the sealing integrity required for hydraulic and fluid-contact applications in wall saws.
- Exact Dimensional Fit — Matches the original O-Ring profile precisely, seating correctly in the groove without stretching, pinching, or rework.
- Broad Wall Saw Compatibility — Confirmed fitment for WS482HF, WS440HF, WS442, and WS482 wall saws. Cross-reference part number 576425101 against your parts diagram before ordering.
- Leak Prevention — A correctly installed O-Ring maintains internal pressure and prevents fluid ingress or egress, allowing the wall saw to sustain consistent cutting force and hydraulic performance.
- Fluid System Safety — A degraded or incorrectly sized O-Ring can lead to hydraulic fluid leaks, creating slip hazards and uncontrolled pressure loss during cutting operations. Using the correct OEM part directly addresses this risk.
An O-Ring is a circular elastomeric seal fitted into a machined groove to prevent fluid or air from passing between two mating surfaces. In wall saws like the WS482HF and WS482, O-Rings are found throughout hydraulic circuits and water-cooling passages, where they maintain the pressure boundaries essential to consistent blade speed and cooling flow. When an O-Ring ages, hardens, or becomes compressed beyond its serviceable limit, it loses its ability to seal effectively — resulting in leaks, pressure drop, and potential damage to surrounding components.
