The Genie 40318GT is a genuine OEM O-Ring Seal for the pump, designed for a wide range of Genie personnel lifts and articulating boom lifts including the AWP Super Series, IWP Super Series, DPL-25S, DPL-30S, DPL-35S, Z-30/20 N, Z-34/22 N, Z-34/22 DC, Z-30/20HD, and TMZ-34/19. As a genuine OEM part, it is manufactured to the same specification as the original component installed at the factory, ensuring a correct, drop-in fit at the pump sealing point. Cross-reference part number 40318GT against your machine's parts manual to confirm it is the right seal for your unit before ordering.
Key Features
- Genuine OEM Material Grade — Manufactured to OEM specification with the correct elastomer compound and dimensional tolerances for a proper pump seal interface.
- Direct-Fit Replacement — Engineered to seat correctly at the pump without modification, restoring the original sealing geometry.
- Broad Genie Fitment — Fits AWP Super Series, IWP Super Series, CWP Super Series, DPL personnel lifts, and Z-series articulating boom lifts including the TMZ-34/19.
- Leak Prevention — A sound O-ring seal maintains fluid integrity at the pump. A worn, cracked, or deformed seal allows fluid to escape, leading to pressure loss and pump performance degradation.
- Safety-Critical Sealing Component — On aerial lifts, a compromised pump seal can affect the lift and drive functions that operators depend on. Replacing a failed seal promptly with the correct OEM part supports safe, intended machine operation.
An O-ring seal forms a compressed, circular barrier between mating components at the pump, preventing fluid from escaping the circuit. Over time, heat cycles, pressure fluctuations, and normal wear cause O-rings to harden, crack, or deform, breaking the seal and allowing fluid to weep or leak. Replacing a failed pump O-ring with the correct OEM seal — such as this Genie 40318GT — restores proper sealing and protects the surrounding components from contamination and fluid loss.
