Turcon Stepseal for Demag HC1020

The Turcon Stepseal, part number 25576340, serves as a hydraulic seal for the Demag HC1020 crawler crane. It is installed within hydraulic cylinders to maintain pressure and prevent fluid bypass between the piston and the cylinder wall. This component is essential for the operation of systems such as boom lift, extension, or outrigger cylinders, where it facilitates controlled and precise movement during heavy lifting tasks.

This seal is compatible with the Demag HC1020 model. The design features a two-piece configuration, typically consisting of a PTFE sealing ring and an elastomer energizer. This construction is engineered to provide a seal under reciprocating motion in high-pressure hydraulic environments.

Hydraulic seals of this type function by creating a barrier that contains pressurized fluid within the cylinder chamber. By maintaining this seal, the component prevents internal and external leaks that would otherwise lead to pressure loss, erratic cylinder performance, or reduced load capacity. Regular inspection and replacement of these seals are standard procedures in hydraulic maintenance to ensure the continued efficiency of the crane's lifting systems.
