SEAL KIT - HYDRAULIC CYLINDER (Yale YT129710021)

YT129710021: A damaged seal kit can allow hydraulic fluid to bypass the piston, reducing cylinder force and causing slow or erratic movement. During disassembly, a worn seal kit often reveals hardened or cracked sealing lips that no longer contain pressure. The seal kit's primary function is to prevent fluid leakage between the cylinder barrel and the moving rod or piston. Keeping the sealing elements in sound condition helps maintain consistent actuation and prevents external drips that create slip hazards. This aftermarket replacement part references the Yale catalog number YT129710021. The item ships at approximately 0.014 pounds. Verify the serial number or application, then call (562) 693-7748.
