Abstract
A pressure tapping comprises first valve means selectively operable to be in an open or a closed setting, and second valve means connected to an outlet from the first valve means, which second valve means tends to be closed when fluid pressure acts on it from the said outlet, so that accidental leakage of fluid from the pressure tapping, by failure to close the first valve means when the adapter is removed from the pressure tapping, is less likely.
