This report summarizes data obtained from testing of type III Teflon gaskets used on PUREX-type process jumper connectors. The purpose of these tests was to asses the performance characteristics of the type III gaskets, currently planned to be used in the Hanford Waste Vitrification Plant (HWVP). Results indicate that the Teflon gaskets deform severally under heat and applied moment loads. The gaskets also lose their ability to hold pressure when thermally cycled, and cannot hold elevated pressures unless they are retorqued between cycles. Gasket failure ultimately occurs after one or more cycles.
