Key Features
- Genuine OEM Elastomer Specification — manufactured to Husqvarna's exact compound and durometer rating, ensuring the correct compression and sealing performance for power cutter operating pressures and temperatures
- Drop-In Sealing Fit — sized to the original groove dimensions, so this O-Ring seats correctly without trimming, shimming, or modification
- Broad K-Series Compatibility — fits the K650, K700, and K650CutnBreak power cutters, covering multiple machines in Husqvarna's professional handheld cutting lineup
- Leak-Free System Integrity — a correctly installed O-Ring maintains internal fluid or pressure containment, preventing seepage that can lead to power loss or accelerated wear on surrounding components
- Verified Part Number Cross-Reference — cross-reference part number 740480703 against your machine's parts diagram before installation to confirm the exact sealing position
An O-Ring is a precision-molded elastomeric seal that sits in a machined groove to create a pressure- or fluid-tight barrier between two mating surfaces or components. In a power cutter like the K650 or K700, O-Rings are used throughout the fuel, cooling, and hydraulic or lubrication circuits to prevent leaks and maintain the correct operating environment inside the machine. When an O-Ring hardens, cracks, or deforms over time, it loses its ability to seal, resulting in fluid leakage, pressure drop, or contamination ingress — all of which can degrade cutting performance and cause damage to adjacent components if left unaddressed.
