Extended Evaporation Lighter Gasket - Fits Most Fluid Lighters for Longer Burn Time

These fit all my zippo lighters perfectly. Do they stop them from evaporateting fluid anymore so then the stock cover that the zippos come with? That's yet to be seen. I use my zippo daily and seem to fill it up about the same as if I didn't install this, but it has a place for a extra flint and that's just fine for me.I used to smoke and was refilling my Zippo every few days.I've since quit, but still carry the Zippo out of habit and convenience.I noticed my fuel would be dry every few days even without constant use. (Nothing more embarrassing than "Sure I have a lighter... *flick, flick, flick, flick")This product extends the fuel lifespan to several weeks between fills.I also like that it holds a spare flint (I used to keep several under the felt).This is a must have for someone who carries a Zippo, whether they use it every day or barely ever use it.These things are great. I smoke about a pack to a pack and a half a day and I have not had to refill my zippo yet and it’s been a week. I have seen reviews that are unsure or deny the life extension of your fuel. It is undeniable. I used to have to fill every 3 to 4 days prior to installing. Make sure you don’t take out cotton or pad from the lighter. Place this over the top and push tight so that it is flush. Great for a smoker.Wish something like these were invented 45 years ago. Tried one in my Zippo for about a month. Did have to add a bit of cellucotton after removing the felt. I use my Zippo daily. Under my use, a single filling lasted 6 days. No leaks in my pocket after filling as recommended. A good add on for a Zippo.They aren't bad. Seems like it runs longer between fills maybe 50% longer. Carry in pocket tho so evaporation takes place. Does great w alcohol fuels for lighting a pipe as i hate the scent of the petro fluidWill it fit perfect. So i dont know if it last longer your fliudOne didn't fitI tested my Zippo with these inserts and with the standard one. There is no difference.
