Frequently Asked Questions
Q: What is the AC305 seal and what does it do?
A: The AC305 is a dynamic hydraulic seal that prevents pressurized fluid from leaking past the pump piston. It is critical for maintaining pump pressure and lift force on Noblelift AC55 jacks.
Q: What material is the AC305 seal made from?
A: The AC305 seal is manufactured from synthetic elastomer designed to withstand mineral-based hydraulic fluid, maintain elasticity across temperature ranges, and provide a reliable barrier against pressure loss.
Q: What symptoms indicate the AC305 seal has failed?
A: Replace the AC305 if the jack will not hold load, if fluid drips from the pump, if pumping requires excessive force, or if pressure drops immediately after lifting. These are signs of seal degradation.
Q: How long does the AC305 seal last under normal operating conditions?
A: In typical warehouse use with regular maintenance, the AC305 seal lasts 2-4 years. Seals degrade faster in high-temperature environments or with contaminated hydraulic fluid.
Q: Is the AC305 seal compatible with non-Noblelift pallet jacks?
A: The AC305 is engineered for the Noblelift AC55 pump bore and pressure rating. Do not substitute for other seal brands or models without verifying dimension and pressure compatibility.
Q: Can the AC305 seal be combined with other AC-series parts for optimal pump performance?
A: Yes. The AC305 seal works as part of a complete pump system with the AC303 piston and AC304 dust ring. Replacing all three together extends pump lifespan and restores consistent lift performance.
