The Genie 48402GT is a genuine OEM Seal Kit for the 42407, 42559 cylinder, built for Genie Z-34/22 Bi-Energy and Z-34 IC articulating boom lifts. Sourced directly from Genie, this seal kit delivers an exact match to the original seals installed at the factory, ensuring the cylinder it services returns to proper working condition. Cross-reference part number 48402GT against your machine's parts manual to confirm it is the correct kit for your unit before ordering.
Key Features
- Genuine OEM Sealing Materials — Manufactured to Genie's original material and dimensional specifications, so every seal in the kit meets the same compression and durability standards as the parts it replaces.
- Cylinder-Specific Fit — Engineered specifically for the 42407, 42559 cylinder; each seal profile matches the bore, rod, and gland geometry of that assembly without adaptation.
- Confirmed Fitment — Compatible with Genie Z-34/22 Bi-Energy and Z-34 IC articulating boom lifts; verify part number 48402GT against your serial number in the parts manual before ordering.
- Restores Cylinder Integrity — Worn or damaged seals allow fluid to bypass the piston or escape past the rod, causing the cylinder to drift or lose extension force. A fresh seal kit restores full holding and actuation capability.
- Complete Service Kit — Supplied as a matched set covering the sealing points of the cylinder, so all wear items are renewed in a single service event rather than one at a time.
A cylinder seal kit contains all the sealing elements needed to rebuild a hydraulic cylinder — typically including piston seals, rod seals, wiper seals, and any backup rings or O-rings used at the gland and port connections. Over time, these seals degrade from pressure cycling, heat, and contamination, allowing fluid to leak past the piston or out along the rod. When that happens, the cylinder loses the ability to hold its position or generate full force, which directly affects boom movement and positioning on the machine. Replacing the full kit restores the cylinder to a serviceable condition and prevents the gradual fluid loss that leads to sluggish or unpredictable boom response.
