The Genie 102298GT Cummins B4.5 O-Ring Seal is a genuine OEM seal designed for the S-100, S-105, S-120, and S-125 telescopic boom lifts. As a direct OEM replacement, this seal is manufactured to the same specifications as the original part, ensuring correct fit within the Cummins B4.5 engine used in these machines. Cross-reference part number 102298GT against your machine's parts manual to confirm it is the correct seal for your unit before ordering.
Key Features
- Genuine OEM Material Grade — Produced to Genie OEM standards, this O-ring is dimensionally correct and made from a compound rated to maintain an effective seal under the operating conditions of the Cummins B4.5 engine.
- Exact-Fit Replacement — Engineered to seat correctly in the same groove or port as the original, this seal installs without modification for a secure, leak-free connection.
- Confirmed Fitment for S-Series Booms — Fits Genie S-100, S-105, S-120, and S-125 telescopic boom lifts equipped with the Cummins B4.5 engine.
- Maintains Fluid Integrity — A sound O-ring seal keeps fluid from weeping past joints and connections. A worn or damaged seal allows leakage that can affect engine operation and lead to more extensive repairs if left unaddressed.
- Operational Safety on Elevated Equipment — On a telescopic boom lift, maintaining the integrity of every engine seal is essential to consistent, dependable operation at height. Using the correct OEM seal supports ongoing mechanical reliability.
An O-ring seal creates a compressed barrier at a joint, port, or fitting, preventing fluid from escaping past mating surfaces. On the Cummins B4.5 engine fitted to these Genie S-series boom lifts, O-ring seals are used at various connection points to keep fluid where it belongs. When an O-ring hardens, cracks, or takes a permanent set, it loses its ability to seal effectively, resulting in leakage at the joint it serves. Replacing a worn seal promptly with the correct OEM part — confirmed by cross-referencing 102298GT with your parts manual — restores the tight, leak-free fit the engine requires.
