  • Thank you  a lot for your answer, I am not using the Teflon inside the purge valve and I clean it with the solvent  acetonitrile   so as to avoid the  contented, 

    sorry these links don't open so I can:t see  the pictures 

    The O-ring is the P/N 5067-6595 1260 PV O-ring FKM5lpack it's cut so I think it is the real problem. and I cant buy another one  for now so  I ask for advice
