The Genie 1257787GT Heated Pressure DEF Hose, 10K is a genuine OEM DEF hose built for the Genie GTH-844 telehandler. As a direct OEM replacement, this hose is manufactured to the same specifications as the original part, ensuring correct fit and compatibility with the GTH-844. Sourced directly through authorized channels, it delivers the assurance of a part designed specifically for this machine. Verify part number 1257787GT against your GTH-844 parts manual to confirm it is the correct hose for your unit before ordering.
Key Features
- Genuine OEM Construction — Built to Genie's original material and pressure specifications for the DEF circuit, ensuring the hose meets the thermal and chemical demands of DEF fluid handling at 10K pressure.
- Integrated Heating Element — The built-in heating element keeps DEF fluid flowing in cold operating conditions, preventing the line from freezing and maintaining emissions system function.
- Direct OEM Replacement — Matches the original hose routing, end fittings, and pressure rating of the factory part, allowing straightforward installation on the GTH-844.
- Confirmed Fitment — Designed specifically for the Genie GTH-844 telehandler; cross-reference part number 1257787GT with your parts manual before ordering.
- DEF Compatibility — Constructed from materials chemically compatible with diesel exhaust fluid, resisting degradation that standard hose materials can suffer when exposed to DEF over time.
- Emissions System Integrity — A sound, leak-free DEF hose is essential to keeping the machine's DEF and SCR system functioning correctly; a cracked or failed hose can trigger fault codes and take the machine out of service.
A heated DEF pressure hose carries diesel exhaust fluid from the DEF tank to the dosing system at the pressure and temperature needed for the SCR emissions system to operate correctly. The heating element built into the hose prevents DEF — which freezes at approximately 12°F (-11°C) — from solidifying inside the line during cold-weather operation. When this hose cracks, leaks, or loses its heating function, DEF flow is interrupted, which can trigger fault codes, derate the engine, or take the machine out of service entirely; replacing it promptly with the correct OEM part restores normal operation.
