Key Features
- Genuine OEM Material Grade — Manufactured to Husqvarna's original compound and compression specifications, delivering the correct sealing performance required in hydraulic and fluid-handling circuits.
- Exact 3/4 Sizing — This sealing ring matches the original port and bore dimensions, seating correctly without modification against mating hydraulic fittings and housings.
- Broad Fitment Across Husqvarna Construction Equipment — Compatible with PP325E, PP455E, and 965156408 power packs, the WS460 wall saw, and the RC455 compactor, covering hydraulic connections across multiple machine families.
- Hydraulic Integrity Restored — A correctly seated sealing ring maintains system pressure and prevents fluid weepage that would otherwise lead to power loss or inconsistent tool performance.
- Fluid-System Safety Compliance — Using the correct OEM seal ensures hydraulic connections remain leak-free under operating pressure, supporting safe and code-compliant operation on the jobsite.
A sealing ring forms a pressure-tight barrier at hydraulic fittings, ports, and connections, preventing fluid from escaping around threaded or push-fit joints. In hydraulic power packs and wall saw systems, even a minor seal failure can cause a gradual loss of working pressure, reducing the torque and cutting force delivered to the tool. When a sealing ring becomes brittle, compressed, or damaged, it allows fluid to bypass the joint — resulting in visible leaks, reduced system efficiency, and potential contamination of surrounding components. Replacing a worn sealing ring with the correct OEM part restores a proper hydraulic seal and returns the machine to its intended operating pressure.
