4. FAQ

Q: Why are multiple materials adopted for these seals?
A: Combined materials deliver strong wear resistance, oil resistance and pressure resistance to adapt to tough working conditions.

Q: Can I put the old seals back for reuse?
A: It is not allowed. Disassembled seals lose elasticity and get deformed, so they cannot seal well.

Q: What issues will defective seals cause?
A: Oil leakage occurs, system pressure declines, and the cylinder moves slowly with reduced working power.

Q: What preparation is needed before installation?
A: Fully clean the cylinder wall and piston rod, clear residues and check for scratches on the surface.

Q: Do we need to add sealant while installing?
A: No. Extra sealant may clog pipelines and lead to hydraulic system failures.

Q: What if a seal is damaged during assembly?
A: Replace it with a new one at once. Any small damage will cause persistent oil leakage.

Q: How do we check if seals need replacement?
A: Check for oil seepage around the rod. Sluggish cylinder movement is also an obvious warning sign.

Q: Are generic seal kits good alternatives?
A: No. Cheap alternatives wear out fast and bring more frequent maintenance troubles.
