Key Features
- Genuine OEM Sealing Material — manufactured to Husqvarna's exact material specification, delivering the compression and chemical resistance required for hydraulic and mechanical sealing applications in construction equipment
- Drop-In Replacement — this sealing washer installs directly in the original position with no rework, maintaining the correct clamping load and seating geometry of the factory assembly
- Broad Multi-Platform Fitment — compatible across Husqvarna wall saws, power packs, power cutters, wire saws, and compactors, including the WS220, WS482HF, PP440HF, PP480HF, K3600, CS10, CS2512, and RC455 series
- Leak Prevention — a properly seated sealing washer maintains fluid containment and pressure integrity; a worn or damaged washer can allow leaks that compromise hydraulic performance and create contamination risks
- Fluid System Safety — hydraulic fluid leaks caused by a failed sealing washer present both a slip hazard and a fire risk on active jobsites; replacing a worn washer with a correct OEM part restores safe, compliant operation
A sealing washer creates a pressure-tight, leak-free joint at threaded or flanged connections in hydraulic and fluid-carrying systems. It works by compressing against mating surfaces when torqued, filling any micro-gaps that would otherwise allow fluid to escape under pressure. When a sealing washer becomes deformed, cracked, or loses its elasticity, the joint loses its integrity — resulting in fluid leaks, pressure drop, and potential damage to surrounding components. Replacing it promptly with the correct OEM part restores the sealed connection and protects the broader hydraulic circuit.
