PTFE wear rings are used in control & regulating apparatus because of its lowest coefficient of friction, wide fluid application range, resistance to cold flow etc. Mechanical properties of PTFE can be improved by adding fillers such as Carbon, Graphite, Bronze etc.
Application & Usage
The function of a PTFE wear ring is to guide the piston and piston rod, absorbing transverse forces. It prevents metal-to-metal contact optimizing the sealing performance.
Virgin PTFE and Filled grades like Bronze, Glass and MOS2
