4. FAQ

Q: What is the main function of this seal kit?
A: It prevents hydraulic oil leakage, maintains stable system pressure, blocks external dust and debris, and protects the cylinder’s internal components from wear and contamination.

Q: Can I reuse old seals after taking them out of the cylinder?
A: No, it is not recommended. After long-term use, the seals lose their elasticity and become permanently deformed, so they cannot provide reliable sealing anymore.

Q: What problems will occur if the seals fail?
A: Hydraulic oil will leak out, leading to pressure loss, slow cylinder movement, reduced lifting power, and potential damage to the entire hydraulic system.

Q: What should I do before installing the new seal kit?
A: Disassemble the cylinder, thoroughly clean the bore and piston rod, remove all old seal residue and debris, and check the rod for scratches or wear that could damage the new seals.

Q: Do I need special tools to install these seals?
A: Yes, professional seal installation tools are highly recommended to avoid damaging the delicate sealing lips during assembly.

Q: What should I do if a seal gets damaged during installation?
A: Stop the installation immediately and replace the damaged seal with a new one from the kit, as even a small scratch can cause persistent leaks.
