As a direct OEM replacement, this orifice is manufactured to the exact dimensional specification required for correct fluid metering in the circuit it serves. Cross-reference part number 74991GT against your machine's parts manual to confirm it is the correct item for your unit before ordering.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Genie's exact 0.028" bore specification, ensuring the orifice meters flow at the correct rate for the circuit it serves.
- Direct OEM Replacement — Drops into the same position as the original component; no adaptation or rework needed to install this part.
- Confirmed Fitment — Designed for Genie Z-series articulating boom lifts, including the Z-34 IC, Z-25/8, Z-20/8, and Z-20/8N.
- Consistent Flow Control — A correctly sized orifice maintains controlled, predictable fluid flow through the circuit; an undersized or oversized opening can cause erratic movement or sluggish response.
- Genuine Genie Quality — Sourced directly from Genie as an OEM part, so the material grade and bore tolerance match the original specification exactly.
An orifice is a precisely sized restrictor fitted into a fluid circuit to control the rate of flow passing through it. By limiting flow to a set volume, it governs the speed and smoothness of the functions it serves — when the orifice is worn, blocked, or incorrectly sized, those functions can become erratic, too slow, or too fast. Replacing a damaged or incorrect orifice with the right OEM part restores the metered flow the circuit was designed around and brings movement back to its intended, controlled behavior.
