5. FAQ

Q: What materials make up the seals in this kit?
A: The kit uses a combination of materials: polyurethane, nitrile rubber, fluororubber, PTFE, and a fabric-reinforced wear sleeve, each tailored to different pressure and friction points in the cylinder.

Q: What is the main purpose of this seal kit?
A: It prevents hydraulic oil leakage, maintains stable internal pressure, keeps out dust and debris, and protects the cylinder’s piston and rod from wear and contamination.

Q: Can I reuse old seals after disassembling the cylinder?
A: No, it is not recommended. Used seals lose elasticity and develop permanent deformation under heat and pressure, so they cannot form a reliable seal again.

Q: What happens when the seals fail?
A: Hydraulic oil will leak, causing pressure loss, slow cylinder movement, reduced lifting power, and even damage to other parts of the hydraulic system.

Q: What preparation work is needed before installing the new 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 burrs that could damage the new seals.

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