Teflon piston ring for Terex RT780

The Teflon piston ring, part number 7170187, serves as a sealing element within the hydraulic cylinders of heavy machinery. It is positioned between the piston and the cylinder wall to prevent fluid bypass, ensuring that hydraulic pressure is converted effectively into linear motion. By maintaining a tight seal, this component supports the operational efficiency of the hydraulic system.

This specific component is compatible with the Terex RT780 rough-terrain crane. It is utilized within the hydraulic cylinder assemblies that manage the movement of the boom and outriggers. Proper installation of this ring helps maintain the required pressure levels for these systems during operation.

In hydraulic systems, piston rings are used to separate the high-pressure and low-pressure sides of a cylinder. Their primary function is to contain the hydraulic fluid, which allows the cylinder to generate the force necessary to lift loads or extend structural components. When these rings wear, internal leakage can occur, which may lead to a reduction in force or slower movement of the hydraulic actuators. Regular inspection and replacement of sealing components are standard practices for maintaining the performance of hydraulic equipment.
