Description

PILOTSEAL 570 is a superior performance and quality biaxially orientated PTFE sheet material which is highly conformable which makes it ideally suited to both standard and irregular flanges.

Applications

  • PILOTSEAL 570 is specially designed for low bolt torque applications and irregular flanges. It is ideally suited for use on glass lined vessels, ceramic or plastic flanges or any application where there is an uneven surface finish and is suitable for use with a wide spectrum of chemicals across the whole pH range.
  • PILOTSEAL 570 has extremely low gas permeability aned excellent creep resistance

Chemical Compatibilities

For the pH range 2 -12, the packing is suitable for dilute acids and alkalis, oils, solvents, steam and water
