PTFE-C25 T125 - black
General
T125-C25 is a PTFE (Polytetrafluorethylene) filled with 25% carbon powder. The fillers make the
material more resistant to “cold flow” and provide the necessary properties to use it as composite seal
with energizer to withstand high pressures. It has similar chemical resistance and can be used in the
same temperature range like virgin PTFE and is especially used in rotary applications. T125-C25
should not be used for dynamic applications in water.
