Good To Know
Q: What does a seal kit do? A: A seal kit replaces worn rubber components inside a hydraulic cylinder, stopping fluid leaks and maintaining pressure. Rebuilding with this kit can extend the cylinder's service life.
Q: How do I know this fits my cylinder? A: Verify your cylinder's bore and rod measurements are 1-3/4" and 1" respectively, and check for the K663304 cross-reference. Fit can vary by serial number, so always confirm before ordering.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
