SEAL KIT - HYDRAULIC CYLINDER (Toyota TY00591-42494-81)

TY00591-42494-81: A worn seal kit can allow hydraulic fluid to bypass the piston, reducing cylinder force and causing slow or erratic movement. This aftermarket replacement part references the Toyota catalog number TY00591-42494-81. 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, which creates slippery surfaces and potential contamination. During operation, degraded seals may also permit internal leakage, leading to loss of holding pressure. The item ships at approximately 0.222 pounds. Verify the serial number or application, then call (562) 693-7748.
