The Genie 54428GT is a genuine OEM Hydraulic 90° O-Ring Fitting built for a wide range of Genie equipment, including SX and S series telescopic boom lifts, Z and ZX series articulating boom lifts, GTH series telehandlers, and TML light towers. As a factory-sourced component, this fitting meets the original design specifications for the hydraulic circuits it serves. Confirm part number 54428GT against your machine's parts manual to verify it is the correct fitting for your unit before ordering.
Key Features
- Genuine OEM Construction — Manufactured to Genie's original specifications, with correct O-ring groove geometry and thread form to ensure a leak-free seal at the fitting junction.
- 90° Angle Configuration — The right-angle design routes fluid lines cleanly in space-constrained areas, maintaining proper line routing without stress on adjacent components.
- O-Ring Face Seal Design — The O-ring sealing interface delivers a reliable, pressure-rated connection that resists weeping and leakage better than tapered-thread alternatives.
- Direct OEM Replacement — Installs in place of the original fitting with no modification, preserving the integrity of the hydraulic circuit it serves.
- Broad Equipment Compatibility — Fits multiple Genie equipment families, including SX and S telescopic booms, Z and ZX articulating booms, GTH telehandlers, and TML light towers.
A hydraulic fitting connects two fluid lines or a line to a component, maintaining a sealed, pressure-rated junction within the hydraulic circuit. The 90° configuration allows the line to change direction at the connection point, which is essential where straight fittings would kink a hose or interfere with surrounding structure. An O-ring face seal fitting relies on an elastomeric O-ring compressed between machined faces to form the seal, making it highly resistant to leaks under pressure. When a fitting cracks, corrodes, or loses its seal, fluid escapes the circuit — causing pressure loss and leaving the machine unable to operate correctly. Replacing a damaged fitting promptly with the correct OEM part restores circuit integrity and prevents further fluid loss.
