The Genie 107740GT is a genuine OEM Check Valve, 25 PSI designed for Genie telescopic and articulating boom lifts and GTH telehandlers, including models SX-150, SX-180, SX-135 XC, SX-105 XC, SX-125 XC, S-80 J. As a direct OEM replacement sourced through Genie's authorized parts network, this check valve is built to the same specification as the original component installed at the factory, ensuring hydraulic system integrity across the full range of compatible machines. Cross-reference part number 107740GT against your Genie parts manual to confirm fitment for your specific model and serial range before ordering.
Key Features
- Genuine OEM Hydraulic Specification — Rated at precisely 25 PSI cracking pressure, this check valve matches the original hydraulic circuit design so flow and back-pressure characteristics remain within the system's engineered parameters.
- Direct-Swap Installation — Manufactured to the same port thread type, body dimensions, and pressure rating as the original, this part drops into the existing hydraulic line without reworking fittings or adapters.
- Broad Boom and Telehandler Coverage — Fits Genie SX super-boom and S telescopic boom lifts, Z and ZX articulating booms, and GTH telehandlers, covering a wide range of DC, FE Hybrid, and XC variant machines.
- Protects Hydraulic Circuit Integrity — A functioning check valve prevents unintended fluid backflow that can cause boom drift, sluggish actuation, or pressure loss in critical lift and extension circuits.
- Aerial-Lift Safety Relevance — On boom lifts operating at significant working heights, uncontrolled hydraulic drift caused by a failed check valve creates a direct risk to operator safety; replacing a worn valve restores the positive pressure hold the system depends on.
A check valve is a one-way flow control device within a hydraulic circuit. It allows pressurized fluid to pass freely in one direction while blocking reverse flow, maintaining pressure downstream so that cylinders — such as those controlling boom lift, extension, or platform leveling — hold their position without creeping or drifting. When a check valve fails, internal leakage bypasses the valve seat, causing gradual or sudden loss of holding pressure that can manifest as unintended boom movement, slow response, or complete loss of function in the affected circuit. Replacing a worn or damaged check valve restores the directional flow control the hydraulic system requires to operate safely and responsively.
