The Genie 58330GT is a genuine OEM O-Ring OR-151 N73038 (74994) built for Genie Z-series articulating boom lifts, including the Z-34/22 Bi-Energy, Z-30/20 N, Z-34 IC, and Z-30/20. As a direct OEM replacement, this O-ring is manufactured to the same material and dimensional standards as the original, ensuring a correct fit the first time. Cross-reference part number 58330GT against your machine's parts manual to confirm it is the right item for your unit before ordering.
Key Features
- Genuine OEM Material Grade — manufactured to Genie's original compound and dimensional specification, delivering the same compression and sealing performance as the factory-installed part.
- Direct-Fit Replacement — matches the original O-ring profile exactly, dropping into place without modification for a clean, confident installation.
- Broad Z-Series Fitment — confirmed for the Z-34/22 Bi-Energy, Z-30/20 N, Z-34 IC, and Z-30/20 articulating boom lifts.
- Leak Prevention — a sound O-ring maintains a fluid-tight seal at its joint; a worn or cracked one allows fluid to weep, leading to pressure loss and component damage if left unaddressed.
- Operational Safety — on aerial boom lifts, a failed seal can compromise fluid pressure and affect machine function; replacing a degraded O-ring promptly keeps the equipment performing as intended.
An O-ring is a circular elastomeric seal seated in a groove between two mating components. Its purpose is to block fluid from escaping the joint under pressure. Over time, heat cycling, fluid exposure, and compression set cause the material to harden, crack, or deform, allowing fluid to bypass the seal. Replacing a worn O-ring with the correct OEM part — confirmed by cross-referencing 58330GT in your Genie parts manual — restores the sealed interface and prevents fluid loss at that connection.
