Comparation of rubber o-ring,PTFE encapsulated o-ring and FFKM o-ring
Advantage | Disadvantage | |
Rubber o-ring |
simple structure and wide application; cheap price | Easy to wear, poor corrosion resistance and poor gas permeability |
PTFE Encapsulated o ring | Combines the elasticity of rubber with the chemical resistance of PTFE, which has excellent chemical resistance, gas permeability and extremely low friction coefficient. | High hardness, however,hardness could be decreased by encapsulated hollow core rubber o-ring |
FFKM o-ring | Has advantage of rubber O-ring and a good chemical resistance, high temperature resistance | Very very expensive |
We manufacture the above three types o-rings. Our FEP/PFA O-rings are made of high-quality raw materials,certified by SGS ROHS, REACH and FDA. They have the advantages of ordinary rubber o-rings and can replace the costly FFKM O-rings. The quality is reliable and the price is more competitive
