The Genie 1284323GT O-Ring, 3.737 x.103 Buna is a genuine OEM sealing component built for Genie S-series telescopic boom lifts, including the S-65 XC, S-40 XC, S-45 XC, S-40 TRAX, S-45 TRAX, S-40 HF, S-45 HF, S-60 J, and S-80 J. Sourced directly from Genie, this O-ring matches the exact material grade and dimensional spec of the original, ensuring a proper seal without modification. Cross-reference part number 1284323GT against your machine's parts manual to confirm it is the correct item for your unit before ordering.
Key Features
- Genuine OEM Material Grade — Buna-N (nitrile) compound delivers the compression resilience and fluid compatibility specified for this application, maintaining a consistent seal over the service life of the component.
- Exact Dimensional Spec — The 3.737 x .103 inch cross-section matches the original O-ring exactly, seating correctly in the groove without stretching, pinching, or gaps that allow fluid past the seal.
- Direct OEM Replacement — Manufactured to Genie's original specification, this O-ring installs in place of the original with no rework to the mating components.
- Broad S-Series Compatibility — Fits multiple Genie S-series telescopic boom lift variants, including XC, TRAX, HF, and J models across the S-40, S-45, S-60, S-65, and S-80 lines.
- Leak Prevention — A sound O-ring maintains a tight seal at its joint; a worn, cracked, or extruded ring allows fluid to bypass the seating surface, leading to external weeping and pressure loss in the circuit it serves.
An O-ring is a precision-molded loop of elastomer that creates a pressure-tight seal between two mating surfaces or around a moving shaft. When seated correctly in its groove, it is compressed just enough to fill the interface and block fluid from passing through. Over time, heat cycling, pressure fluctuation, and chemical exposure cause the rubber to harden, crack, or take a permanent set — at which point the seal fails and fluid begins to escape. Replacing a worn O-ring with the correct OEM part, matched to the right compound and cross-section, restores the seal and prevents the ongoing fluid loss and component wear that a leaking joint causes.
