Compound O-Ring

[ Features ]

Compound 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.

[ Main properties ]
We can produce other no-nominal compound o-ring.
