Review on 🔥 AmerStar 10-Pack Enhancing Fuel Gas Can Jug VENT CAPS with Retaining Lip - Effortless Installation on Gas Can for Quicker, Seamless Pouring (10 PCS) by Ricardo Ware

I bought these gaskets for use on kerosene can necks and lid inserts. The fit is excellent, however they are almost unusable because. The gasket absorbs the kerosene, swells, and the rubber becomes _very_ sloppy, to the point where the gasket loosens, if at all, by rubbing on the threads when the spout or liner is inserted into the cap. Over time they regain their integrity as the kerosene evaporates, but in everyday use they are almost always wet with the contents of the canister.
