The Genie 106123GT is a genuine OEM End Cover O-Ring, 4HP/4HB built for a range of Genie scissor lifts and boom lifts, including GS scissor lifts, S telescopic booms, and Z articulating booms. As a direct OEM replacement, this seal is manufactured to Genie's specifications, ensuring correct material grade, dimensional conformity, and compression characteristics for the application. Compatible models include the GS-3384, GS-3390, GS-4390, GS-5390, S-60 J, Z-34/22 N, Z-51/30J, Z-33/18, Z-34/22 IC, Z-33 DC Power, and Z-34 IC, among others. Cross-reference part number 106123GT against your machine's parts manual to confirm this is the correct seal for your unit before ordering.
Key Features
- Genuine OEM Sealing Material — Manufactured to Genie's material and compression specifications for an end cover seal, ensuring the correct durometer and sealing performance for this application.
- Direct-Fit Replacement — Dimensioned to seat correctly in the end cover groove, eliminating the need for trimming, shimming, or adaptation during installation.
- Broad Genie Fitment — Fits GS scissor lifts, S series telescopic booms, and Z series articulating booms across multiple model variants; verify with your parts manual for your specific unit.
- Preserves Sealing Integrity — A sound end cover O-ring prevents fluid weepage at the cover interface; a degraded or cracked seal allows fluid loss and should be replaced promptly with the correct OEM part.
- Backed by Genie OEM Sourcing — Supplied as a genuine Genie part through DHS Equipment, so you receive the exact component specified for these machines rather than an approximate substitute.
An end cover O-ring forms the primary seal between an end cover and the component body it closes, preventing fluid from escaping at that joint. When the O-ring is in good condition, it compresses evenly in its groove and holds a leak-free seal under normal operating pressure. Over time, heat cycling, compression set, and exposure to fluid cause the rubber to harden, crack, or deform, at which point the seal begins to weep or leak and must be replaced. Fitting the correct OEM-specified part — one matched to the right size and material grade for the 4HP/4HB application — restores the seal to its original condition and prevents further fluid loss.
