Good To Know

Q: How do I know if my cylinder needs this seal kit? A: Visible fluid weeping around the cylinder rod or a loss of lifting power are common signs of worn seals. Replacing them early helps prevent rod and bore damage from contaminated fluid.

Q: Does this kit cover a full cylinder rebuild? A: This kit supplies the sealing components for a standard cylinder reseal job. Check the bore and rod for scoring before rebuilding, since damaged metal surfaces will destroy new seals.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
