5PCS Lighter No Evaporation Gasket … (Black)

They've been working great in all my Zippos.Nice and Thick Plastic that has stood up to the heat of long burns & it has remained it's original strength.The only thing is refilling my Zippo I have to have a tool to open the port (Because, I don't have any finger nails.).But, everything stays sealed up.

My old F XIII zippo dosnt have the fill hole in the lift up felt at the bottom of the lighter. My F 04 has the fill hole in the felt. So i switched the felts from my new to my old zippo. ( what i did with the new zippo is an other review) It mostly worked. A little to much wadding under the felt of my old zippo.It will fit older models. It fit like a plug in my newer 04 so well i left it out of the case for 12 hrs. It lit after a few flicks.( ya i forgot to put it back in the case after filling once. Thats how i know. Camping) It helps prevent evaporation.

Installed 2 of the 5 in 2 Zippos and they have remained fueled well past when they usually go dry, long term we'll see but so far they do the job, saw these on a youtube vid originally. I don't smoke but a good flame is great for sealing synthetic cord ends and there's often something that requires a flame. Dec 25 Update, both Zippos I use them on still have fuel, I don't use em that often but the fuel I put in when I installed these is still there.To get around the small hole issue I bought some small syringes wo needles,Karlling Pack of 5 X 10 ml 10cc Syringes Without Needlehttps://www.amazon.com/gp/product/B013WWFJX0/ref=ppx_yo_dt_b_asin_image_o01_s00?ie=UTF8&th=1

I don’t smoke. My Dad always told me to carry one for emergencies. The one issue I’ve seen with Zippos is evaporation. The gasket fits well and holds an additional flint. Double win. I’ll check and see how well it works. But at the outset I’m very happy with this product.I grabbed a 2mm thick Ti lighter from China last year with an included gasket at hinge. It works well. I added this gasket to that lighter. Hopefully with the extra gasket the evaporation will cease entirely or greatly.The only other thing I could think of to reduce evaporation is to get a Zorro lighter body with the brass wick cap when closed. However, how much do you need to spend on the perfect evaporation proof lighter when the ROI takes too long as I don’t use it very often.

I don't think these really do anything. I found a video online of someone using a corner of a sandwich bag and that works ten times better.

I tested with 4 zippos 2 with and 2 without these caps. I tested how much longer they retain the fluid then switched lighters and tested again on average with these caps they retained fluid and extra two+ weeks. Great product

Whoever came up with this invention should get a prize. It's pretty hard to improve on the Zippo design, but these little rubber gaskets really improve the lifespan of a fluid refill. I've used them in 3 of my Zippos (dating from 2005 to 2022) and they fit perfectly, and I'm going much longer than refills than I used to. It's an A-1 product.

I sure can't see why people are complaining about these things. I use the Zippo fluid that comes in the black can and I have had no problems with these things ever getting hard or falling out. I've been using the same one now, which is the first one I put in, for 6 months with no issue at all. Love it.
