Key Features
- Genuine OEM Material Grade — manufactured to Genie's original dimensional and material specifications, so this seal compresses and seats correctly within the pump housing.
- Direct-Fit Replacement — engineered to install in place of the original without rework, keeping replacement straightforward for field or shop technicians.
- Broad GTH Telehandler Coverage — fits the GTH-636, GTH-844, GTH-1056, GTH-1256, GTH-1044, GTH-1244, GTH-1544, GTH-644, and GTH-842 telehandler models.
- Fluid Retention — a sound pump seal prevents fluid weeping or leakage at the pump, keeping the circuit operating at the pressure the system requires.
- Verified Part Number — ordering by Genie part number 138077GT ensures you receive the correct seal profile for this pump application, not a generic substitute.
A pump seal closes the interface between rotating and stationary pump components, preventing fluid from escaping around the pump shaft or housing joint. When this seal wears, cracks, or takes a set, fluid begins to weep past the sealing surface, causing a loss of pressure and visible leakage at the pump. Replacing the worn seal with the correct OEM part — the Genie 138077GT — restores the tight sealing surface the pump needs to maintain consistent fluid delivery to the circuit it serves.
