Review on Acxico 3Pcs Brass Gas Refill Adapter for S.T Dupont Memorial Lighter - Improved SEO by Greg Baker

Well they go through the nozzle on the butane refill bottle - not in cans with Dupont style threads, but in the usual neon or vector refill cans. I didn't use any other adapter inside - as you can see from one of the seller's photos, only for a metal nozzle in a can. lighter. This allows you to refuel your lighter and reduce the amount of fuel that leaks out the side and returns to you when you refuel your lighter. It's not ideal as there is some kickback, but it's better than using the plastic adapter that comes with many butane cans (break them off the can lid). I'm glad I bought the product as it reduces the hassle and wasted fuel I had trying to use the plastic adapters that come with butane refill bottles. It doesn't screw into the gas station well, but you can see that in the photos provided by the seller. All three adapters are the same size - a hole in the end if good in all three parts which was a comment in another review that there was an issue with one of them not having a hole drilled in the end - it wasn't here . I probably should have tried the brass weights from the tackle box as they are very similar. The bottom line is that it works, and while it's not perfect, it's better than what I had and it works. I'd hesitate if I had a $400-$900 lighter to use them and buy a Dupont brand canister or screw-in refill adapter.
