This O-Ring is engineered to the exact material grade and dimensional tolerances specified by Husqvarna, ensuring a proper seal across compatible machines including the K770, K970, K760, K750, K650, K950, K960, K700, K760II, and K950Rescue power cutters, as well as the PP440, PP440HF, PP455E, PP480, PP480HF, and PP492 power packs, and the DM406 concrete core drill. As a genuine OEM part, it matches the original component in compression rating and material composition for a dependable, long-lasting seal. DHS Equipment supplies this part to help keep your equipment running at full performance.
Key Features
- OEM-Grade Seal Material — manufactured to Husqvarna's exact compound and compression specifications, delivering the same sealing integrity as the original part
- Exact Dimensional Fit — machined to precise cross-section and diameter tolerances so this O-Ring seats correctly in its groove without modification
- Broad Husqvarna Fitment — compatible with K-series power cutters including the K770, K970, K760, and K650, plus PP-series power packs including the PP440HF, PP480HF, and PP455E, and the DM406 core drill
- Leak Prevention — a correctly seated O-Ring maintains fluid and pressure containment within the machine; a degraded or incorrectly sized seal allows leaks that can compromise hydraulic performance and internal components
- Genuine OEM Confidence — cross-reference part number 740431300 against your Husqvarna parts diagram to confirm the correct application before installation
An O-Ring is a precision loop seal that sits in a machined groove to create a pressure- or fluid-tight barrier between two mating components. In power cutters and power packs, O-Rings are used throughout the hydraulic and fluid circuits to prevent leaks at connection points, housing joints, and valve assemblies. When an O-Ring hardens, cracks, or deforms with age or heat exposure, it loses its ability to maintain a proper seal, leading to fluid loss, pressure drop, and potential damage to surrounding components. Replacing a worn O-Ring promptly with the correct OEM part restores the integrity of the sealed system and keeps the machine operating as intended.
