PTFE step seal is used for hydraulic cylinder piston sealing with o ring together, o ring provide the elasticity to compresate the wear of PTFE ring to some extent. So PTFE step seal has the function of two-way sealing. Material:
PTFE ring: Bronze filled PTFE
O ring: NBR/FKM/high eastic nylon
Working temperature: -20~+80 ℃( Nylon O-ring)
-20~+250 ℃(FKM O-ring)
For piston hole sealing: For piston rod sealing:
Properties: Good static/dynamic sealing perfermance Low breakout friction, no stick-slip behavior High abrasion resistance property Low and high temperature application range Simply installation
