SEAL KIT - HYDRAULIC CYLINDER (Toyota TY00591-20465-81)

TY00591-20465-81: A damaged seal kit can allow hydraulic fluid to bypass the piston, reducing cylinder force and causing slow or erratic movement. During a rebuild, the seal kit replaces all worn seals, O-rings, and wipers inside a hydraulic cylinder. The kit's primary function is to contain pressurized fluid and exclude contaminants from the cylinder bore. A common failure consequence is external leakage that creates slippery surfaces and fluid loss. Keeping a seal kit in sound condition helps maintain consistent cylinder extension and retraction speeds. This aftermarket replacement references Toyota catalog number TY00591-20465-81. Verify the serial number or application, then call (562) 693-7748. The item ships at approximately 0.272 pounds.
