The Genie 1258121GT Cylinder Seal Kit is a genuine OEM replacement built for GTH-1048 and GTH-1056 telehandlers. As a direct OEM part, it is manufactured to the same specifications as the original, ensuring correct fit and material compatibility right out of the box. This kit covers the part seals needed to restore cylinder integrity on these telehandler models — cross-reference part number 1258121GT against your machine's parts manual to confirm it matches your specific unit before ordering.
Key Features
- OEM-Grade Seal Materials — Genuine Genie seals are produced to the same material grade and dimensional tolerances as the originals, so compression and sealing performance meet the demands of the cylinder.
- Complete Kit Format — All seals needed for the cylinder service interval are packaged together, simplifying the rebuild process and reducing the risk of missing a component mid-job.
- Confirmed Fitment for GTH-1048 and GTH-1056 — Engineered specifically for these two Genie telehandler models, removing the guesswork from parts sourcing.
- Restored Cylinder Performance — Worn or damaged cylinder seals cause fluid weepage and loss of cylinder holding force. Fresh OEM seals restore proper cylinder function and prevent further fluid loss.
- Operational Safety — A cylinder that cannot maintain pressure under load is a safety concern on any telehandler. Replacing seals at the first sign of weeping keeps the machine operating as designed.
A cylinder seal kit contains the full set of seals required to rebuild a hydraulic cylinder — typically including piston seals, rod seals, wiper seals, and O-rings depending on the cylinder design. Over time, these seals degrade from heat, pressure cycles, and normal wear, leading to external fluid weepage or a cylinder that drifts or loses holding capacity under load. Replacing the complete seal set restores the cylinder's ability to hold and move loads reliably, and it is significantly more cost-effective than replacing the entire cylinder assembly.
