As a genuine OEM part sourced directly through Genie's supply chain, it is built to the same specifications as the original components it replaces.
Key Features
- Genuine OEM Seal Grade — manufactured to the same material and dimensional standards as the original seals, ensuring proper compression and sealing integrity within the valve assembly.
- Direct-Fit for Manifold 139391GT — this kit is engineered specifically to service manifold 139391GT, so the seals align correctly without modification.
- Serial-Number-Specific Fitment — verified for Z-51/30J units from SN Z452510A-39751 and from SN Z452511B-1607; cross-reference your serial number to confirm applicability.
- Restores Valve Function — worn or degraded valve seals allow fluid to bypass the valve, causing erratic or unresponsive control behavior; replacing them with this kit restores proper valve operation.
- Operational Safety — correct valve sealing is critical to consistent boom control on aerial lifts; using the right OEM seal kit helps maintain the integrity of the control circuit it serves.
A valve seal kit replaces the seals within a valve body that would otherwise allow fluid to leak past internal components, reducing the valve's ability to regulate flow and pressure accurately. On an articulating boom lift, a valve that leaks internally can cause sluggish, inconsistent, or uncontrolled boom movement, which affects both productivity and safe operation. Replacing the seals at the correct service interval — or when leakage is detected — restores the valve to its original performance and keeps the machine operating as intended.
