The Genie 139512GT is a genuine OEM Valve Seal Kit designed for Genie S series telescopic boom lifts and Z series articulating boom lifts. As an authorized OEM part, this seal kit is manufactured to the exact material and dimensional specifications required for a correct, lasting repair. It fits a wide range of S series models — including the S-40, S-45, S-60, S-60 XC, S-60 TRAX, S-65, S-65 XC, S-65 TRAX, S-80, S-80 XC, S-85, and S-85 XC — as well as select Z series articulating booms including the Z-45/25, Z-45/25J IC Power, Z-51/30J, Z-60/34, and Z-62/40. Always cross-reference part number 139512GT against your machine's parts manual to confirm this is the correct kit for your unit.
Key Features
- Genuine OEM Sealing Material — Manufactured to Genie's original compound and durometer specifications, ensuring each seal in the kit delivers the correct compression and fluid containment for the valve it services.
- Complete Kit, Direct Installation — Supplied as a complete seal kit so all serviceable seals in the valve assembly are replaced in a single service event, reducing the risk of a repeat repair from a missed seal.
- Broad S and Z Series Coverage — Fits a wide range of Genie telescopic and articulating boom lifts, from compact S-40 and S-45 models through full-size S-85 XC and Z-62/40 machines.
- Restored Valve Function — A worn or degraded valve seal allows fluid to bypass or weep past the valve, causing sluggish or erratic boom movement. Replacing the seals with this kit restores proper valve response and consistent boom control.
- Operational Safety — Valve integrity directly affects boom movement and hold. Seals that have deteriorated can compromise the valve's ability to maintain position under load, making timely seal replacement an important part of safe boom operation.
A valve seal kit contains the seals and o-rings that keep fluid contained within a valve body and prevent internal bypass between ports. When these seals wear, harden, or take a set over time, the valve can develop internal leakage — leading to slow or inconsistent boom response, visible weeping at the valve body, or an inability to hold position under load. Replacing the full set of seals restores the valve to proper operating condition and prevents minor seepage from developing into a more significant fluid loss or control issue.
