4 Pcs Dual Gas Refill Adapter Brass Lighter Gas Refill Adapter Fluid Fuel Gas Refill Adapter Compatible with St Dupont Lighter, Gold

ST Dupont probably doesn't like this 4 piece refill adapter set but they work. And I can fill Dupont lighters using a good quality (double or triple refined) butane gas which means I don't have to purchase the crazy expensive Dupont gas. I wish I would have discovered these years ago.

These little adapters work great with a plastic chipped butane can. If you have the lighter that they fit - which I cannot remember the picture is not large enough for me then these will work for you. I recommend them

I recently came into a really expensive light that needed this adapter. It works well very high quality and doesn’t spill any butane as I’m refilling my lighter. Thank you for making this product.

Although well executed, unfortunately, we did not served, it's intended purpose. None of the attachment facilitated a smooth flow to any of the lighters I acquired the attachment for. So be it.

Simple adapter. I noticed a bit of a gap with the hole even though it stated the size of the hole is around 1.8mm. But when used with the butane, it didn't cause any leakage. It charged perfectly.
