Boom Lift Swivel Seal Kit 7017127 – Optimized Product Page Content (E400AJP)

🔹 Product Overview
The Boom Lift Swivel Seal Kit with JLG Part Number 7017127 is a critical, genuine Original Equipment Manufacturer (OEM) or high-quality aftermarket seal set specifically designed for the Boom Swivel/Articulation Cylinders found on various JLG Electric Boom Lifts, including the popular E400AJP model.
These articulation cylinders are essential for the JIB movement (articulation joint between the main boom and the platform) or other smaller boom sections that utilize an internal swivel mechanism. The seals within these cylinders endure constant pressure cycling and movement. When they wear, they can cause external hydraulic fluid leakage (weeping rod) or internal bypass, leading to instability or drift in the articulated boom sections.
The 7017127 seal kit provides all the necessary components (seals, wipers, O-rings) to rebuild the cylinder to OEM specifications, eliminating leaks and restoring the precise, safe control required for accurate platform positioning on the E400AJP.1
