SEAL KIT - HYDRAULIC CYLINDER (Toyota TY00591-72597-81)

TY00591-72597-81: A worn seal kit can allow hydraulic fluid to bypass the piston, reducing cylinder force and causing sluggish movement. This aftermarket replacement part references Toyota catalog number TY00591-72597-81. The seal kit contains multiple sealing elements that prevent fluid leakage between moving and stationary cylinder components. A common failure consequence is external oil seepage past the rod seal, which leads to visible drips and gradual fluid loss. During operation, degraded seals may also permit internal leakage, resulting in diminished holding pressure and drift under load. The item ships at approximately 1.05 pounds. Verify the serial number or application, then call (562) 693-7748.
