The Genie 1271789GT is a genuine OEM Tube Assembly with 12 Swivel Nuts designed for Genie GS large-frame scissor lifts, including the GS-3384, GS-3390, GS-4390, and GS-5390. As a direct factory replacement, this assembly delivers an exact fit without the guesswork — simply cross-reference part number 1271789GT against your parts manual to confirm compatibility with your machine's serial range. Sourced directly through authorized channels, this component meets the same specifications as the original part installed at the factory, making it the straightforward choice for operators and service technicians keeping large-capacity GS scissor lifts running at full performance.
Key Features
- Genuine OEM Construction — Manufactured to the same material and dimensional standards as the original, ensuring the swivel nut fittings seat and seal correctly every time.
- Direct Bolt-In Replacement — Designed to install into the existing hydraulic or pneumatic tube routing on GS large-frame models without rework or adaptation to mounting points.
- Broad GS Large-Frame Fitment — Compatible with the GS-3384, GS-3390, GS-4390, and GS-5390 scissor lifts, covering Genie's heaviest-duty rough-terrain and high-capacity slab scissor platforms.
- Integrated Swivel Nut Fittings — The 12 pre-installed swivel nuts allow flexible line routing and connection alignment, speeding up reassembly and reducing the risk of cross-threading during installation.
- System Integrity at Height — A correctly functioning tube assembly maintains consistent fluid or pressure delivery throughout the lift's range of motion — a worn or damaged tube can result in pressure loss, erratic platform movement, or system fault codes on GS scissor lifts.
A tube assembly on a large-frame GS scissor lift routes hydraulic fluid or pneumatic pressure between key system components, enabling the lift cylinders, brake circuits, or auxiliary functions to operate as designed. The swivel nut fittings at each connection point allow the tube to mate cleanly with hoses and ports even when angles are not perfectly aligned, which is critical on machines that flex and articulate during platform travel. When a tube assembly develops a crack, corrosion, or a fitting that no longer seals, the result is pressure bleed-off, fluid contamination, or a complete loss of function in the circuit it serves — making prompt replacement essential to keeping the machine safe and operational.
