4 in 1 Gas Refill Adapters for S T Dupont Lighter Yellow Red Green Blue Caps

I have a st DuPont ligne 2 with the yellow cap and the adapter with the little green o ring worked perfect for me.

I bought this product to refill my st DuPont lighters using a regular can of butane fuel. But several things happened in between my purchase and my first use. This product came packed in a plastic bag with each one packed in a single smaller plastic bag. No instructions about how to use it. The smaller bags had some letters on them. I presumed they were in Chinese… but not sure. The letter in our alphabet didn’t match the st DuPont “nomenclature” which is color coded. So, at the end you have to figured out what belong to what… so, basically this parts are useless.

This does work for St. Dupont lighters that need the gold bottle refill. You should do your own research on figuring out if one of the adapters in the set works for your lighter, but once you figure that out, the adapters work very well.

I’ve been smoking for 30 years at least. And I like my lighters. Spent tons of cashola on S.T. Dupont, and Dunhill lighters over the years. I had a stockpile of the single fill Dupont butane refills from back in the day which is great because they decided to stop making those, and make larger butane cans with a cheap plastic nozzle that “screws” onto the corresponding lighter. Horrible move by them. Butane goes everywhere. I used to get a 10 pack of single fills of whatever color for about $40. They worked perfectly. Put the lighter in the freezer for a couple minutes, fill it up in 2 seconds. No wasted butane.The new DuPont cans are about $25 and get you maybe 3 refills. Maybe more. Depends on how much goes shooting all over your hands.These type of adapters have been around for ages. I always resisted because to me, I’m not going to bother putting $5 butane in a $1000 lighter. But now, they don’t give you much choice.So I pulled the trigger and these are my results.The gold adapter works perfectly. No wasted butane. Filled 3 of my lighters wonderfullyRed adapter works, but lost a some butane. Will probably look for a better version as the lighter I use mostly needs red.Green also works, but boy the butane was shooting everywhere. I even tried the old method of putting the lighter in the freezer. Did not help much. The crazy thing is the green adapter has an O-ring which theoretically should help it seal better. It got the job done though.Didn’t use the blue adapter.All in all, it’s worth it enough. You lose about as much butane as the official new Dupont butane cans. So you might as well pick up a pack of these. Maybe some better quality ones out there though.

The adapter for "Red capped" Dunlop lighters is too short when the O-ring is used thus resulting in a severe loss of butane. The story is these adapters machined in China with poor tolerances.

Bought these so I could fill an ST Dupont Ligne 1, so that's the only one I've tried so far. Machined brass, nice quality, good fit on the butane can nozzle and no leaks. I'm happy with it.

Good adapters to fix typical poor French design flaws, even though S.T. DuPont is a famous brand.

These fit very loose on the Colibri 300ml butane can making the butane spray out the back due to the seal not being tight enough around the plastic tip of the butane refill can. All four tips were not engineered to the proper specs and are completely useless. 1/26/23 review and refund. I should have listened to other reviewers from Oct 2022 that said the same thing. I'm sad cuz I need the tri-tip one to fill an old 1953 ST Dupont lighter.
