    Dear Sir,

    I have a PTFE based system. The operating fluids are 80% Sulphuric Acid and 55% Hydroiodic Acid. I have detected some leakages in my system near PTFE tube fittings, Valve fittings and tank fittings. I am looking for an Acid (as mentioned above) resistant sealant that could be used with PTFE. Do you have any solution for me.

  5. Graham Marshall Graham Marshall United States says:

    Do you have a sealant that is acid resistant that I can use to cover a pressure sensor that is flexible enough to still transmit the pressure across the sealant layer to the pressure sensor
