This is a hydraulic cylinder seal kit designed to restore the sealing integrity of hydraulic cylinders within CAT equipment. It is manufactured to meet stringent OEM quality standards, ensuring superior performance and durability compared to worn or damaged seals that can lead to internal leakage. Operators may observe a loss of hydraulic system pressure, sluggish cylinder movement, or external fluid leaks when these seals begin to fail.
Always verify with serial number before ordering.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
Initial signs of seal failure include a noticeable decrease in lifting or extending force and slower cylinder response. If ignored, the cylinder may exhibit external fluid leaks and a progressive loss of hydraulic pressure, impacting overall equipment performance. Continued operation with compromised seals can lead to premature wear on other hydraulic components.
Thoroughly clean all internal surfaces of the cylinder housing and piston rod before beginning assembly. Avoid using sharp tools that could scratch or nick the new seals during installation.
Inspect the cylinder bore for scoring and the piston rod for straightness and surface finish during seal replacement.
