Key Features
- Genuine OEM Material Grade — Manufactured to Husqvarna's original compression and sealing specifications, delivering the same leak-resistance as the factory-installed component.
- Direct Drop-In Replacement — Engineered to the exact profile and thickness of the original, this sealing washer seats correctly without modification.
- Confirmed Fitment — Verified for the K760II and K760 power cutters; cross-reference part number 579733701 against your parts diagram before ordering.
- Leak Prevention — A properly seated sealing washer maintains fluid or pressure integrity at its joint; a worn or damaged washer can allow seepage that leads to operational issues and accelerated component wear.
- Fuel and Fluid System Integrity — Where sealing washers are used in fuel or hydraulic circuits, using a correctly rated OEM part is essential to safe and compliant machine operation.
A sealing washer creates a pressure-tight, leak-free joint between mating surfaces such as fittings, bolts, or housing connections. Unlike a standard flat washer, it is designed to deform slightly under torque, filling microscopic surface irregularities to prevent fluid or gas from escaping. When a sealing washer degrades — through heat cycling, overtightening, or age — it loses its ability to maintain a reliable seal, which can result in fluid loss, contamination ingress, or pressure drop that affects machine performance.
