The Genie 94643GT is a genuine OEM Straight Grease Zerk, 5/16-24 built for a wide range of Genie telescopic and articulating boom lifts, trailer-mounted booms, and GTH telehandlers. As a direct OEM replacement, this fitting threads in exactly where the original did, ensuring grease gun compatibility and a leak-free seat from the first service interval. Part number 94643GT is confirmed for Genie S and SX telescopic booms, Z and ZX articulating booms, TZ trailer-mounted booms, and GTH telehandlers including the GTH-644, GTH-842, and GTH-844.
Key Features
- Genuine OEM Fit, 5/16-24 Thread — Machined to OEM thread specification so this fitting seats cleanly without cross-threading or leakage at the grease port.
- Straight Entry Design — The straight-entry body allows direct grease-gun engagement on pivot points and pins where angled access is not required.
- Broad Equipment Coverage — Fits Genie S and SX telescopic booms, Z and ZX articulating booms, TZ trailer-mounted booms, and GTH series telehandlers, making it a useful stocking item for mixed fleets.
- Maintains Lubrication Intervals — A damaged or seized fitting prevents grease from reaching the bearing or pin surface it serves; replacing it promptly keeps lubrication schedules on track.
- Genuine Genie OEM Part — Sourced directly from Genie, this component meets the same material and dimensional standards as the part it replaces, with no substitution risk.
A grease zerk — also called a grease nipple or grease fitting — is the access point through which lubricant is forced into a bearing, pin, or pivot joint during routine maintenance. The fitting contains a small spring-loaded ball that opens under grease-gun pressure to admit lubricant and then seals to prevent contamination from entering the joint. When a zerk is damaged, corroded, or stripped, the grease gun cannot form a proper seal and lubricant bypasses the joint entirely, leaving the pin or bearing surface dry. Replacing a failed fitting with the correct OEM part restores full lubrication access and protects the joint from accelerated wear.
