The Genie 634397GT is a genuine OEM O-Ring built for Genie GTH series telehandlers. Sourced directly from Genie, this replacement seal meets the same material and dimensional standards as the original part installed at the factory. It is confirmed to fit GTH-2506, GTH-3007, GTH-5519, and related GTH variants including AU, AU.2, AU.3, AU-AG, ACF, and FMS configurations.
Key Features
- Exact Dimensional Fit — Matched to the original cross-section and inner diameter so this O-Ring seats correctly in its groove without trimming or adjustment.
- Broad GTH Variant Coverage — Fits GTH-2506, GTH-3007, and GTH-5519 across multiple regional and configuration variants, including AU, AU.2, AU.3, AU-AG, ACF, and FMS models.
- Maintains Sealing Integrity — A sound O-Ring prevents fluid weepage at joints and fittings; a cracked or flattened one allows leaks that can lead to component wear and unplanned downtime.
- Genuine Genie Part — Cross-reference part number 634397GT against your machine's parts manual to confirm this is the correct O-Ring for your unit before ordering.
An O-Ring is a circular elastomeric seal that sits in a machined groove between two mating surfaces or at a threaded fitting, creating a pressure-tight barrier that prevents fluid from escaping the joint. When an O-Ring ages, hardens, or becomes pinched during assembly, it loses its ability to conform to the mating surfaces and weeping or active leaks develop at that connection. Replacing a worn O-Ring promptly with the correct OEM part restores the seal and protects surrounding components from fluid contamination or starvation.
