Which butane do I need for my Defi Extreme or XXTreme Lighter?
Defi series of lighters use the tall red can of S.T. Dupont butane. Read the full guide for more details about refilling and compatibility.
Why won't my torch lighter ignite?
Torch lighters do not use a flint in the same way as soft flame models. If your lighter is properly filled and still will not ignite, it may need professional service or repair. Please contact us for repair assistance.
