YUSUD 5PCS Lighter Gasket Seal, Anti-Evaporation Accessories for Lighter Insert (Black)

UPDATE Nov 2025. After a little over a year, the hinge on the fill cover broke. It still seems to seal well. I refill it quite often, so I won’t gig the product. It did survive over a year of constant opening/closing…and I bought the 5-pack. I’m still happy with it. I am one of many who has had chemical burns on my legs from leaky lighter fluid, so I decided to give one of these gaskets a try. Gosh...I wish I had done this sooner. It has worked brilliantly so far. No leaking, much longer periods in between refueling, and I can even carry a spare flint under the fill cap. I was having to fill my lighter after every 4-5 days or so, now I can go over a week and it still lights the first time. Clearly, the gasket has helped prevent fuel evaporation. While the gasket did not sit flush with the edge of the lighter core bottom, I figured out that it was likely by design, as the lighter body still had no problem sliding into it's casing. I've seen some reviews where folks have mentioned trimming the edge of the gasket, but I would avoid that unless you absolutely cannot get the body to slide into the casing. The only concern I had was the small size of the fill hole on the bottom, but that concern has vanished now after a few fillings. Don't hesitate...this is a great upgrade for any normal-size Zippo.

Grrr. The product is great, but I don't see anywhere that I'm supposed to remove the felt. It may be somewhere, but I just can't find it. I had to Google to find out about the felt. So far good product & doesn't deserve to lose a star. Might suck later, but now I'm impressed

Works well allows the fluid to last another week. Wish Zippo design their fluid chambers so that they're more sealed this corrects that problem but fluid still escapes through the wick. There are great instructions you do take out that felt pad so this fits right back in I don't get why people leave reviews or questions mentioning doesn't fit but it fits perfectly. I use a couple of different lighters especially a rechargeable arc one when I'm at home kind of was getting tired of filling the Zippo and the fuel isn't great smelling. I have another Zippo that has a torch single torch that is I prefer that and will probably get another one. This company gives you I believe five of these items that if you have more lighters you can add to. Just wish the little door on this item to add the fluid would seal more tightly.

Bid farewell to the hassle of frequent lighter refills and embrace the enduring flame of Zippo longevity with the YUSUD 5PCS Lighter Gasket Seal! I recently outfitted my Zippo lighters with these seals, and I must say, they've revolutionized my experience. Installation was a breeze – no need for intricate tools or specialized skills. The rubber material itself exudes durability, promising sustained performance for the long haul. However, the true hero of this story is the remarkable fuel savings. Thanks to these seals, my lighters now retain fluid for at least three times longer than before! It's akin to witnessing magic (albeit rooted in science, but let's indulge in the wonder of it all). Frankly, these seals ought to be standard issue with every Zippo straight out of the box! Now, let's address some misconceptions. I've stumbled upon a few negative reviews citing issues like short flints or butane conversion woes. But hold your judgment, dear readers. Those individuals might be reviewing an entirely different product. This YUSUD offering isn't about converting to butane or providing flints; it's a top-notch rubber gasket meticulously crafted to curb fuel evaporation, and it excels at its task with aplomb. If you're weary of the perpetual cycle of Zippo refills, the YUSUD 5PCS Lighter Gasket Seal is a game-changer. With its effortless installation, robust construction, and significantly prolonged fuel life, it's a resounding 5-star champion in my repertoire. So wave goodbye to frustration and revel in the everlasting flames ignited by these modest yet indispensable rubber marvels!

These little rubber seals work extremely well. The lighter lasts maybe 3-5 times longer than if it had the regular felt pad on the bottom. You have to be careful not to overfill it however because the only place it can leak out from is the top wick. I wouldn’t fill it more than 8ml or so just to be safe. Great product. I can’t believe it isn’t more popular. Update: as I was opening the bottom to refill and take a picture of the cotton inside, the lid broke off. It still works fine but it is no longer physically attached to the hinge. Not sure if the lighter fluid deteriorates the rubber but still a good product. The lid still seals the bottom. If it starts leaking I will replace it. These are the real deal gaskets. I recently bought another brand that had a ten pack because they were cheep. They were not totally sealed up because they were the wrong size. They shrunk up and became hard and fit even worse. These are a bit more expensive but they are worth the money. The rubber will not shrink and fits perfectly. I will buy this brand every time!

The fluid in my zippo last longer because of these. I have zippo’s that don’t use these and another 5 zippos that do. These gaskets make the zippos more reliable and less prone to needing to be refilled.

I don't feel this is effective in saving lighter fluid to be honest. But, what I do like is it compresses the cotton wool in the lighter a tad, and I like the spare flint holder. A ranger band works better for fuel life extension IMO. Still, a fun product and I am keeping mine I think I bought around 4 or 5.

For under 6 bucks it will pay for it self over time, the trick is the rectangle compressed fuel tab, don't take it out take a small screwdriver and push it in all around then put the rubber seal in then insert spring and fuel up. Some people take that part out then complain it don't work. Follow my tip you will have much better results. Shipping was fast great purchase.

Doesn’t work

Put one on a zippo and left another zippo as per how they come from factory. Filled both and both were empty by the end of a month. If it makes a difference I did not notice it.

A la medida, le quedaron a todos mis zippos

Received in good condition good for the nrmal size lighter of this type , but wold like they will have for slim lighter too my favourite is slim zippo.

Cheap garbage. Might aswell have thrown my money in the wind. Made from the wrong kind of rubber. Srinks and go's stiff. DOES NOT SEAL !
