Key Features
- Genuine OEM Seal Materials — Factory-sourced seal compounds matched to the compression ratings and fluid compatibility required by cylinder 48025, not generic substitutes.
- Cylinder-Specific Fit — Engineered exclusively for cylinder 48025 on the TMZ-50/30, so every seal in the kit corresponds to the correct bore, groove, and seat dimensions of that cylinder.
- Confirmed TMZ-50/30 Compatibility — Built specifically for the Genie TMZ-50/30 trailer-mounted articulating boom, eliminating guesswork when sourcing seal components for this machine.
- Restores Cylinder Integrity — A worn or leaking primary cylinder seal allows fluid to bypass the piston, causing sluggish or uncontrolled boom movement. This kit returns the cylinder to proper operating condition.
- Operational Safety — The primary cylinder controls critical boom positioning on an aerial lift. Maintaining a sound, leak-free seal is essential to predictable, safe platform movement at height.
Seals inside a hydraulic cylinder prevent fluid from bypassing the piston, maintaining the pressure needed to extend, hold, and retract the boom with control. Over time, seals degrade from heat, pressure cycles, and normal wear, leading to internal leakage that causes slow response, drift, or loss of lift capacity. Replacing the seals in cylinder 48025 with the correct kit restores full cylinder performance and prevents further damage to the bore.
