The Genie 1279050GT Master Cylinder Seal Kit is a genuine OEM seal kit built for Genie S series telescopic boom lifts, including XC and HF variants across the S-60, S-65, S-80, and S-85 model lines. As an OEM part, this kit is produced to the exact material and dimensional standards required for a correct, lasting cylinder repair. Cross-reference part number 1279050GT against your machine's parts manual to confirm this is the right kit for your specific unit before ordering.
Key Features
- Genuine OEM Seal Material — Each seal in this kit is manufactured to OEM specifications, ensuring the correct compound grade and dimensional tolerances for a proper cylinder fit and lasting sealing performance.
- Complete Kit for the Master Cylinder — Includes the seals required for a full master cylinder rebuild, reducing the need for multiple separate part orders and keeping your repair on track.
- Direct Replacement Fit — Engineered to install into the master cylinder without modification, maintaining the correct clearances and compression characteristics of the original assembly.
- Broad S Series Compatibility — Fits Genie S-60 XC, S-65 XC, S-60 HF, S-65 HF, S-80 XC, S-85 XC, S-80 HF, and S-85 HF telescopic boom lifts, covering both XC and HF variants of these popular models.
- Restores Cylinder Integrity — Worn or degraded seals allow fluid to bypass the cylinder, causing sluggish or unresponsive movement. Replacing the seal kit restores proper cylinder function and keeps the boom operating as intended.
- Operational Safety — The master cylinder plays a direct role in boom movement and control on aerial lifts. Using the correct OEM seal kit ensures the cylinder performs reliably at working height, where seal integrity matters most.
A master cylinder seal kit contains the internal seals and related sealing components needed to rebuild a cylinder that has begun to leak or lose pressure. Over time, seals degrade from heat, pressure cycling, and normal wear, allowing fluid to bypass the piston and reducing the cylinder's ability to generate and hold force. A cylinder with worn seals may move slowly, drift under load, or fail to hold position — all conditions that affect safe machine operation. Replacing the full seal kit rather than individual seals restores the cylinder to proper working condition and is the recommended approach when internal leakage is detected.
