SEAL KIT - HYDRAULIC CYLINDER (CAT CT277H8-59802)

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 often shows visible cracking or flattening of the sealing lips. Seal kit condition directly affects the cylinder's ability to hold pressure and maintain consistent motion. Keeping a seal kit in sound condition helps prevent external leaks that can create slippery surfaces and fluid loss. This aftermarket replacement part references CAT as the OE maker and carries the cross-reference part number CT277H8-59802. The item ships at approximately 0.1 POUNDS.
