The Husqvarna 574880301 O-Ring is a genuine OEM sealing component designed for the WS440HF, WS440, and WS482 wall saws. As an authentic Husqvarna part, it is manufactured to the exact material grade and dimensional tolerances required for a proper seal in these track-mounted wall saw systems. This O-Ring is a direct replacement for the original, ensuring the correct compression fit within its mating surfaces without any 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 specification, delivering the correct durometer and compression set resistance required for this application.
- Exact Dimensional Fit — Matches the original cross-section and inner diameter, seating correctly in the designed groove without adjustment or reworking.
- Wall Saw Compatibility — Fits the WS440HF, WS440, and WS482 track-mounted wall saws; cross-reference part number 574880301 against your parts diagram to confirm placement.
- Leak Prevention — A correctly seated O-Ring maintains fluid or pressure integrity within the saw's hydraulic or coolant circuit, preventing costly leaks and protecting surrounding components.
- Genuine Husqvarna OEM Part — Sourced directly from Husqvarna's construction equipment parts program, ensuring consistent quality and traceability for every service interval.
An O-Ring is a precision-molded loop seal that sits within a machined groove to prevent the passage of fluid or air between two mating surfaces or components. In a wall saw system such as the WS440HF, WS440, and WS482, O-Rings are used throughout the hydraulic circuit and water-feed connections to maintain pressure and prevent leaks. When an O-Ring degrades, becomes compressed, or is damaged during disassembly, the result is fluid seepage, pressure loss, or contamination that can impair cutting performance and accelerate wear on nearby components — making timely replacement with the correct part essential.
