Teflon ring for Terex HC230

The Teflon ring, identified by part number 0669 722 21, functions as a sealing or support component within the Terex HC230 crane. It is typically employed in hydraulic or pneumatic assemblies to maintain system integrity. This component may be found in cylinders, valves, or other areas where precise sealing and friction reduction between moving parts are required.

This part is compatible with the Terex HC230 model. It is manufactured from polytetrafluoroethylene (PTFE), a material selected for its low coefficient of friction and chemical resistance. Proper installation of this ring helps maintain the performance of the hydraulic or pneumatic circuits in which it is installed.

Teflon rings of this type act as secondary seals or backup rings in heavy machinery. They are designed to support primary seals by preventing extrusion under pressure and reducing wear on sliding surfaces. By providing a low-friction interface, these rings assist in the smooth operation of mechanical systems, ensuring that internal pressures are contained effectively during crane operation.
