Potential Hazards of Teflon Gaskets in Liquid Fluorine Systems
Recent developments in the use of liquid fluorine as a fuel for space vehicles has created a requirement to establish safety criteria which will eliminate potential hazards in the plumbing systems and holding tanks. An area of extreme potential hazard is the use of porous Teflon gaskets which contain organic solvents. When Teflon is processed through cleaning cycles containing trichloroethylene, the Teflon can absorb a sufficient quantity of solvent to cause incompatibility with liquid fluorine, creating a violent reaction.
