The Genie 1278854GT is a genuine OEM Orifice Disc built for the Genie Z-45 XC articulating boom lift. Sourced directly from Genie, this part meets the original design specification for the Z-45 XC, ensuring it seats and performs exactly as the machine was engineered to require. As a genuine OEM component, it carries the same part standards as the disc installed at the factory. Cross-reference part number 1278854GT against your Z-45 XC parts manual to confirm it is the correct item for your unit before ordering.
Key Features
- Genuine OEM Construction — Manufactured to Genie's original dimensional and material standards, so the disc fits and functions exactly as designed for the Z-45 XC.
- Direct Drop-In Replacement — Engineered to the same geometry as the original, this disc installs in place of the worn or damaged part without rework or modification.
- Correct Fitment for Z-45 XC — Confirmed for the Genie Z-45 XC articulating boom lift; always verify part number 1278854GT in your machine's parts manual before ordering.
- Flow Control Integrity — A sound orifice disc maintains consistent, metered fluid flow through the circuit it serves. A damaged or incorrectly sized disc disrupts flow and can cause erratic or sluggish machine response.
- Operational Safety — Proper flow metering is critical to controlled, predictable boom movement on aerial lifts. Replacing a worn disc with the correct OEM part helps restore the controlled motion the machine depends on for safe operation at height.
An orifice disc is a precisely sized flow-restricting component installed within a fluid circuit to meter and control the rate of fluid passing through it. By limiting flow to a calibrated rate, it governs the speed and smoothness of the movements it serves — such as boom extension or lift functions — preventing sudden or uncontrolled motion. When an orifice disc wears, becomes clogged, or is damaged, the controlled flow it provides is disrupted, which can result in jerky, sluggish, or inconsistent operation that affects both productivity and safe machine handling.
