Hydrogen will leak right through the pipes - it doesn't have to be at a poorly fitted joint. The plastic pipe used for natural gas infrastructure is not dense enough to prevent seepage of the hydrogen. Natural Gas companies tried to install a sealant in the form of aluminum sleeving inside the plastic pipe to allow for future hydrogen distribution, but this proved to be unacceptably expensive.
