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

Doesn’t work

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.

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.

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!
