The Genie 139522GT is a genuine OEM Orifice, 0.030" designed for the Z-51/30J articulating boom lift, specifically for use with manifold 139391GT. As a direct OEM replacement, this orifice meets Genie's original design specifications, ensuring the correct 0.030" bore size for the manifold it serves. Confirm part number 139522GT and the applicable serial number range against your machine's parts manual before ordering to verify this is the correct component for your unit.
Key Features
- Genuine OEM Precision — Manufactured to Genie's exact 0.030" bore specification, ensuring dimensional conformity critical to correct flow control through manifold 139391GT.
- Direct OEM Replacement — Replaces the original orifice in manifold 139391GT without modification, restoring the assembly to its designed operating condition.
- Correct Fitment for the Z-51/30J — Designed specifically for the Genie Z-51/30J articulating boom lift; cross-reference your serial number to confirm applicability for your machine.
- Flow Control Integrity — A correctly sized orifice maintains consistent, metered fluid flow through the manifold circuit; an incorrect or worn orifice can cause erratic or uncontrolled machine movement.
- Operational Safety — On an articulating boom lift, precise flow control through the manifold directly affects smooth, predictable boom operation — using the correct OEM orifice supports safe, controlled machine function.
An orifice is a precisely sized restriction fitted within a fluid circuit to meter and control flow rate. By limiting the volume of fluid that can pass through at a given pressure, it governs the speed and smoothness of the movements driven by that circuit. In a manifold assembly such as 139391GT, the orifice plays a key role in maintaining consistent, controlled operation — if the orifice becomes damaged, blocked, or is replaced with an incorrectly sized part, fluid flow becomes uncontrolled, leading to erratic or unsafe machine behavior. Replacing a worn or damaged orifice with the correct OEM part restores proper flow regulation and predictable boom performance.
