Resistência a alta temperatura FEP PFA Preto FKM Encapsulado PTFE O Rings
Encapsulated O Ring adopts special rubber resisting high temperature, 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 resistant 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.
