SEAL KIT - HYDRAULIC CYLINDER (Toyota TY00591-40356-81)

TY00591-40356-81: A damaged seal kit can allow hydraulic fluid to leak past the piston, reducing cylinder force and causing sluggish or incomplete movement. During a cylinder rebuild, the old seals and wipers are removed and replaced with fresh components from this kit. The kit contains multiple elastomeric seals, O-rings, and backup rings that prevent internal and external leakage. A worn seal kit often leads to visible drips or a steady oil film on the cylinder exterior. Keeping a seal kit in sound condition helps maintain consistent pressure and prevents contamination from entering the cylinder. This aftermarket replacement references Toyota catalog number TY00591-40356-81. Verify the serial number or application, then call (562) 693-7748. The item ships at approximately 0.084 pounds.
