The Genie 55558GT is a genuine OEM Long Orifice M. 0.37 built for Genie GS scissor lifts and TZ articulating booms. As a direct OEM replacement sourced from Genie, this part meets the same design and dimensional specifications as the original component it replaces. Cross-reference part number 55558GT against your machine's parts manual to confirm it is the correct item for your unit before ordering. This orifice fits a wide range of GS models — including the GS-1530, GS-1532, GS-1930, GS-1932, GS-3232, GS-3246, GS-4069BE, GS-4069DC, GS-4069RT, GS-2669RT, GS-3369RT — as well as the TZ-50 and TZ-50/30.
Key Features
- Genuine OEM Conformity — Manufactured to exact Genie OEM dimensional specifications, ensuring the orifice opening is precisely sized for the circuit it serves.
- Broad GS and TZ Fitment — Compatible with multiple Genie GS scissor lift variants — including BE, DC, and RT models — as well as TZ-50 and TZ-50/30 trailer-mounted articulating booms.
- Flow Regulation Integrity — A correctly sized orifice maintains consistent, controlled fluid flow through the circuit it serves; a damaged or incorrectly sized orifice can cause erratic or uncontrolled movement.
- Operational Safety — On aerial lifts, precise flow control directly affects platform movement and positioning — using the correct OEM-spec orifice helps maintain predictable machine behavior.
An orifice is a precisely sized restriction fitted into a fluid circuit to control the rate of flow through that passage. By limiting flow to a calibrated volume, it governs the speed and consistency of the actuator or function it feeds. When an orifice becomes blocked, damaged, or is replaced with an incorrectly sized substitute, fluid flow becomes unpredictable — resulting in jerky, too-fast, or non-responsive machine movement. Installing the correct OEM-specification orifice restores controlled, consistent operation to the circuit it serves.
