Thanks for the response. I spoke to TODO awhile back, but they said it is not for natural gas. I don't need the dry-break system where the coupling seals, as I can vent the line upstream of the coupling. Just need a quick disconnect that will be a sure seal in service.
I am looking for a way to quickly connect/disconnect a 2" or 3" flex hose from an industrial burner. Natural gas supply line, operating pressure 20# / design pressure 100#. Does a quick connect exist that assures no leaks and can prove closed to BMS? Thanks!
