Polytetrafluoroethylene (PTFE) O-rings
Polytetrafluoroethylene (PTFE) O-rings are widely used for chemical applications due to their wide temperature operating range, as well as low moisture absorption properties. These O-rings are hydrophobic, which don't get wet when they come in contact with water.
You need to keep in mind that PTFE O-rings are not compatible with:
High vacuum seals
High temperature steam
Low compression vacuum sealing flanges
