The Genie 128619GT is a genuine OEM Grease Zerk, 1/8 NPT, 67.5° built for Genie Z-34 and Z-30 articulating boom lifts. As a factory-sourced component, this fitting matches the original specification for thread size and angle, ensuring proper installation without additional modification. It is compatible with models including the Z-34/22 Bi-Energy, Z-30/20 N, Z-34/22 IC, Z-34 IC, and Z-30/20. Cross-reference part number 128619GT against your machine's parts manual to confirm it is the correct fitting for your unit before ordering.
Key Features
- Genuine OEM Fit — Sourced directly from Genie, this fitting meets the original thread pitch and angular specification for a secure, leak-free installation at every greased pivot point.
- 1/8 NPT Thread, 67.5° Angle — The 67.5° angled body allows grease gun access in tight or restricted locations where a straight fitting cannot seat properly.
- Broad Z-Series Compatibility — Fits multiple Z-30 and Z-34 articulating boom lift variants, including Bi-Energy, IC, and standard configurations.
- Consistent Lubrication Delivery — A correctly seated zerk allows full grease flow to the joint it serves; a damaged or cross-threaded fitting blocks lubrication and accelerates wear at that pivot.
- Inexpensive Insurance — Replacing a stripped or damaged fitting promptly keeps lubrication intervals on schedule and protects higher-cost pivot components from premature wear.
A grease zerk is a one-way valve fitting threaded into a pivot point, pin boss, or bearing housing. When a grease gun is pressed against it, the spring-loaded ball inside the fitting opens and allows grease to flow into the joint, then reseals when the gun is removed to keep contaminants out. A damaged, stripped, or clogged zerk prevents grease from reaching the joint, which accelerates wear on pins, bushings, and bearings at that location. On an articulating boom lift, where multiple pivot joints carry dynamic loads during operation, keeping every zerk in serviceable condition is essential to maintaining proper lubrication across the machine's articulating structure.
