Key Features
- Genuine OEM Sealing Materials — Produced by Genie to match the original seal grades and dimensional tolerances of master cylinder 1276829GT, ensuring correct compression and seating on reassembly.
- Cylinder-Specific Fit — Engineered exclusively for master cylinder 1276829GT, so every seal in the kit corresponds to the correct bore, groove, and profile for that assembly.
- Broad S-Series Compatibility — Fits the S-40 XC, S-45 XC, S-40 TRAX, S-45 TRAX, S-40 HF, and S-45 HF telescopic boom lifts, covering all major variants of the S-40 and S-45 platform.
- Restores Cylinder Integrity — A worn or leaking master cylinder seal allows fluid loss and pressure drop, compromising control response. Replacing the seals with this kit restores proper cylinder function.
- Operational Safety — Maintaining sound seals in a master cylinder is critical to consistent, predictable control on aerial work platforms. Using the correct OEM kit removes the risk of mismatched seals that can fail prematurely under load.
A master cylinder seal kit contains the internal seals and O-rings needed to rebuild a master cylinder that has begun to leak or lose pressure. Over time, seals degrade from heat cycles, fluid exposure, and normal wear, causing the cylinder to bypass fluid internally or weep externally — both of which affect control feel and machine reliability. Replacing the seals at the first sign of leakage restores the cylinder to proper working condition and extends its service life without requiring a full cylinder replacement.
