Product Overview
The 215-9985 (R) is a boom cylinder seal repair kit featuring a multi-stage seal combination structure with main sealing system and auxiliary seals.
Working Principle
When hydraulic oil enters one chamber of the cylinder, it pushes the piston and drives the piston rod while oil returns from the other chamber. The 215-9985 kit ensures hydraulic oil doesn't leak from the high-pressure chamber and prevents air from entering the low-pressure chamber.
