To help you get started, we’ve put together this guide to ensure you enjoy your Ligne 2 lighter to its fullest. From refilling to troubleshooting, here’s everything you need to know.

You can always check the gas refill cover if you are unsure which butane you require. 

 Using the recommended gas ensures optimal performance and longevity.

2. Which Flint Refills Are Required?

S.T. Dupont Ligne 2 lighters use S.T. Dupont Black Flints. These flints are designed specifically for the Ligne 2 mechanism, providing smooth ignition and protecting the roller from unnecessary wear. Avoid using generic flints, as they may damage the lighter over time.

3. How to Change the Flint and Refill the Gas

Changing the Flint:

  1. Locate the flint chamber inside the lid of the lighter.

  2. Press the small button located on the front of the flint section. The slide should unlock and move out of place.

  3. Remove any remnants of the old flint and insert a new S.T. Dupont Flint.

  4. Pull the slide shut with your hand. This may require effort for brand new lighters as well as some older models.

  4. Let the lighter rest for a minute to stabilize before testing ignition.

5. Troubleshooting Common Issues

Issue: The lighter isn’t igniting.

  • Check if the gas reservoir is empty and refill if necessary.

  • Ensure the flint isn’t depleted and replace it if needed.

Issue: The flame is too weak or inconsistent.

  • Ensure you’re using the correct gas refill for your lighter. 

  • Check if the gas reservoir is empty and refill if necessary.

Issue: The ignition roller spins freely but doesn’t spark.

  • This often means the flint is worn out. Replace the flint to restore functionality.
