SEAL KIT - HYDRAULIC CYLINDER (Toyota TY00591-27270-81)

A damaged seal kit can allow hydraulic fluid to bypass the piston, reducing cylinder force and causing slow or erratic movement. During inspection, a worn seal kit may show visible cracking, hardening, or flattened cross-sections on the O-rings and wiper seals. Seal kit condition directly affects the cylinder's ability to maintain pressure and prevent external leakage. Keeping a seal kit in sound condition helps avoid fluid contamination and component scoring from debris ingress. This aftermarket replacement part references Toyota catalog number TY00591-27270-81. The kit includes multiple elastomeric seals and backup rings designed to contain hydraulic fluid within the cylinder bore. Verify the serial number or application, then call (562) 693-7748. The item ships at approximately 0.308 pounds.
