S.T. Dupont, named for founder Simon Tissot Dupont, is the manufacturer of collectable metal lighters and other men's accessories. When a Dupont lighter ceases to produce a flame, you'll need to refill it with gas cartridges made specifically for S.T. Dupont lighters.

Skill level:


  1. 1

    Turn the lighter's valve cover screw counterclockwise with your fingers to remove it.

  2. 2

    Push down on the valve with a pencil or screwdriver to drain the reservoir and release any pressurised air.

  3. 3

    Screw the gas refill into the refill valve for 1, 2 and GATSBY lighter lines. For mini Jet, MaxiJet, D line or D-light line lighters, insert the gas cartridge into the refill valve and press it down gently. Hold for 5 seconds, and repeat the process until gas starts to leak.

  4. 4

    Replace the valve cover screw and use your lighter.

Tips and warnings

  • Do not refill your lighter near open flames.
