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

These take my zippo lighter fluid refills from lasting 3 days-ish to lasting roughly a week. They nearly double the fuel lifespan inside my zippo insert, maybe a smidge longer if I’m not lighting too often to use up the fuel. These stick in pretty firm once you install them and I haven’t had any problems with leakage either, just be sure you aren’t over filling your lighter. These even help a bit with loose insert creep, although nothing beats a perfect insert fit, these do help a little. Overall these are a no brainer buy if you prefer a soft flame and the original zippo insert. Sure a sealed insert with a wick cap would be best for fuel evaporation, but this isn’t a bad inexpensive alternative either.

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
