Seal Kit 7023528 – Optimized Product Page Content

🔹 Product Overview
The Seal Kit with JLG Part Number 7023528 is a crucial, high-quality seal set designed for the Main Lift Cylinder (sometimes referred to as the extension or tilt cylinder) used on various JLG Electric Scissor Lifts, most notably the popular 3246ES and 2646ES models.1
These lift cylinders are responsible for raising and lowering the entire platform assembly. Because they constantly bear the full weight of the platform, operator, and materials, the seals within the cylinders endure immense pressure cycling. When these seals wear, they cause external fluid leaks (weeping rod) or internal bypass (fluid leaking past the piston). Internal bypass is a severe safety hazard as it causes the platform to drift or creep downward under load.
Using the 7023528 seal kit allows for a complete overhaul of the cylinder, restoring its ability to hold pressure reliably, eliminating leaks, and ensuring the stability and safety of the platform at height.
🔹 Key Features & Benefits
