S.T. Dupont Blue Gas Refill is a dedicated butane refill developed for selected S.T. Dupont lighter models. Designed to match the filling system of compatible lighters, the 30 ml refill provides the correct fuel connection for maintaining reliable everyday operation.
S.T. Dupont uses a colour-coded refill system across its lighter collection, with different lighter families requiring specific refill types. Choosing the correct colour is therefore essential: the Blue refill should only be used with S.T. Dupont models specifically designated for Blue gas.
