The Genie 7-256-27GT is a genuine OEM Male Pressure Check Valve designed for Genie GTH-series telehandlers, including the GTH-636, GTH-644, GTH-842, GTH-844, GTH-1048, and GTH-1056. As a direct OEM replacement, this valve is built to the same specifications as the original component installed at the factory, ensuring a correct hydraulic connection without modification. Cross-reference part number 7-256-27GT against your parts manual to confirm fitment for your specific unit before ordering.
Key Features
- Genuine OEM Hydraulic Integrity — Manufactured to Genie's original pressure and flow specifications, ensuring the valve seats, seals, and checks pressure exactly as the hydraulic circuit requires.
- Direct-Fit Replacement — Male-threaded connection matches the original port geometry on GTH-series telehandlers for a straight swap with no line or fitting adaptation needed.
- Broad GTH Telehandler Coverage — Fits the GTH-636, GTH-644, GTH-842, GTH-844, GTH-1048, and GTH-1056, covering a wide range of Genie telescopic handler configurations.
- Hydraulic Circuit Protection — A correctly functioning check valve prevents backflow and maintains line pressure, keeping the hydraulic system responsive and protecting downstream components from pressure spikes.
- Operational Safety — On telehandler boom and carriage circuits, a failed or leaking check valve can cause unintended load drift. Replacing a worn valve with this OEM part restores proper pressure hold and load-handling control.
A male pressure check valve is a one-way hydraulic valve that allows fluid to flow in a single direction while blocking reverse flow, maintaining pressure in the circuit when the pump is idle or demand shifts elsewhere in the system. On a telehandler like the GTH-series, these valves are critical to boom extension, carriage tilt, and attachment functions — without a properly seating check valve, hydraulic pressure bleeds back through the line, causing slow response, load sag, or loss of boom position. When this valve leaks internally or fails to seat cleanly, operators typically notice sluggish boom movement or gradual drift under load, making timely replacement essential to safe machine operation.
