SEAL KIT - HYDRAULIC CYLINDER (Toyota TY00591-31672-81)

TY00591-31672-81: A damaged seal kit can allow hydraulic fluid to bypass the piston, reducing cylinder force and causing slow or erratic movement. During a cylinder rebuild, the seals inside the gland and piston must be replaced to restore proper sealing. Keeping a seal kit in sound condition helps prevent external leaks that create slippery floors and fluid loss. The aftermarket replacement part references Toyota as the OE maker and cross-references part number TY00591-31672-81. This seal kit is a set of rubber and polyurethane rings designed to contain hydraulic pressure within the cylinder bore. A common failure consequence is internal leakage that leads to drift or inability to hold a load position. Verify the serial number or application, then call (562) 693-7748. The item ships at approximately 0.66 pounds.
