SEAL KIT - HYDRAULIC CYLINDER (CAT CT1146963)

A worn seal kit can allow hydraulic fluid to bypass, reducing cylinder force and causing slow or erratic movement. This aftermarket replacement seal kit references CAT as the OE maker and cross-references part number CT1146963. The seal kit contains multiple sealing elements that prevent fluid leakage between moving and stationary cylinder surfaces. Over time, seals harden and lose elasticity, leading to external drips or internal bypass that degrades system pressure. Keeping a seal kit in sound condition helps maintain consistent cylinder performance during repetitive actuation cycles. The item ships at approximately 0.01 pounds. Verify the serial number or application, then call (562) 693-7748.
