Piston seal construction Cylinder

This is a compact seal that combines several functions in one unit. The outer polyurethane rings act as guides and supports, while the central rubber element is responsible for proper dynamic sealing. This solution ensures stable piston operation under load and resistance to abrasion and high operating pressure.

When to replace the piston seal

A worn cylinder piston seal is manifested by the lifter falling spontaneously, a decrease in lifting force, or oil leaks inside the cylinder. Regular replacement restores full tightness of the system and operational safety of the device.
