The Genie 128620GT is a genuine OEM Grease Zerk, 1/8 NPT, 45 Deg designed for Genie Z-30/20 and Z-34/22 articulating boom lifts. Sourced directly from Genie, this fitting delivers an exact match to the original component, ensuring correct thread engagement and grease-flow angle right out of the box. The 45-degree fitting angle is engineered to reach grease points that a straight fitting cannot access in tight pivot and joint locations on these Z-series booms. Cross-reference 128620GT against your parts manual to confirm the correct service point before installation.
Key Features
- OEM Thread Integrity — Manufactured to Genie specification, this fitting delivers the correct 1/8 NPT thread form and taper for leak-free seating in cast and machined grease ports.
- Angled Access — The 45-degree body puts the grease-gun coupler in a workable position at pivot pins, boom joints, and turntable fittings where straight zerks cannot seat properly.
- Confirmed Fitment for Z-Series Booms — Compatible with the full Z-30/20 and Z-34/22 family, including N, RJ, DC, Bi-Energy, and IC variants — covering the most widely deployed Genie articulating boom models in the field.
- Lubrication System Performance — A properly seated zerk allows grease to reach bearing surfaces under operating pressure; a damaged or clogged fitting starves the joint and accelerates wear on pins and bushings.
- Direct Drop-In Replacement — Installs into the existing threaded port with no re-tapping or adapter required when replacing a stripped, sheared, or clogged original fitting.
A grease zerk — also called a grease nipple or fitting — is the small threaded port through which lubricant is injected into a pivot pin, bearing, or joint during routine service. On articulating boom lifts like the Z-30/20 and Z-34/22, these fittings are located throughout the boom structure, turntable, and axle assemblies, and they must accept a grease-gun coupler reliably under pressure. When a zerk becomes stripped, corroded, or sheared flush with the housing, grease can no longer reach the bearing surface, leading to accelerated wear, stiff or binding articulation, and potential joint failure. Replacing a damaged fitting promptly with the correct part restores the lubrication pathway and protects the surrounding components.
