The Husqvarna 740431100 O-Ring is a genuine OEM sealing component designed for K2500 and K3600 power cutters and the WS440, WS440HF, WS442, WS460, WS462, WS463, WS482, and WS482HF wall saws. As an authentic Husqvarna part, this O-Ring is manufactured to the exact material grade and dimensional tolerances specified for these machines, ensuring a proper seal every time. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- OEM-Grade Sealing Material — manufactured from Husqvarna-specified compound to deliver the correct compression and chemical resistance for hydraulic and fluid-contact applications in these machines.
- Exact Dimensional Fit — engineered to the precise cross-section and inner diameter required for the sealing grooves on compatible power cutters and wall saws, seating correctly without adjustment.
- Broad Fitment Coverage — a single OEM part number covering K2500 and K3600 power cutters and the full WS440, WS460, WS462, WS463, WS482, and WS442 wall saw series.
- Leak Prevention Where It Counts — a properly seated O-Ring maintains system pressure and keeps fluids contained; a worn or damaged ring leads to leaks, pressure loss, and potential component damage.
- Verified Cross-Reference — cross-reference part number 740431100 against your machine's parts diagram to confirm the correct sealing position before installation.
An O-Ring is a circular elastomeric seal fitted into a groove between two mating surfaces or components. Its primary role is to prevent fluid or air from bypassing the joint under pressure, maintaining system integrity throughout operation. When an O-Ring deteriorates — through heat cycling, chemical exposure, or simple age — it loses its ability to compress evenly, allowing leaks that can compromise hydraulic pressure, contaminate surrounding components, and ultimately lead to more significant mechanical failures if left unaddressed.
