Pro-Flex’s offering includes a traditional yellow-jacket version (Pro-Flex 1) and a black-jacket arc-resistant version (Flak Jacket). Both versions can be used with either natural gas or LP and utilize the same dual-seal, gasket and O-ring connection system that virtually eliminates the problem of leaks due to “bad cuts,” the company notes.
