The Genie 66844GT is a genuine OEM O-Ring,.285 X.065 built for TML-4000 and TML-4000N light towers. As a direct OEM replacement, this O-ring is manufactured to the same dimensional specification as the original, ensuring a correct, consistent seal wherever this size is called out in your parts manual. Cross-reference part number 66844GT against your machine's parts manual to confirm this is the correct item for your unit before ordering.
Key Features
- OEM Dimensional Conformity — Manufactured to the exact .285 X .065 profile specified by Genie, ensuring the correct compression and sealing performance in its designated seat.
- Direct OEM Replacement — Sourced directly from Genie as a genuine OEM part, this O-ring installs in place of the original with no modification needed to the mating components.
- Confirmed Fitment — Designed specifically for the TML-4000 and TML-4000N light towers; verify part number 66844GT in your parts manual before installation.
- Sealing Integrity — A correctly sized O-ring maintains a fluid-tight seal at its joint. A worn, cracked, or improperly sized ring causes weeping or leakage that can lead to component damage and unplanned service intervals.
An O-ring is a loop-shaped sealing component seated in a groove between two mating surfaces or around a shaft. When compressed, it forms a barrier that prevents fluid from escaping the joint. Over time, O-rings can harden, crack, or deform under heat and pressure cycles, causing a seal to fail. Replacing a degraded O-ring with the correct OEM part — matched precisely to the .285 X .065 dimensions called out for this application — restores the seal and protects the surrounding components from fluid loss and contamination.
