[ Features ]
|
|
Ptfe O-Ring adopts special rubber resisting high temprature, F+ plastic and special engineering to compound this sealing product. It not only has low contraction permanent set functions of rubber O-ring, but also resist heat, cold, oil, friction, chemical corrusion and other performances. It can be used in all kind of dynamical seal and static seal widely, meanwhile can replace all traditional rubber and plastic o-ring.
