Arrived fast and packaged nicely.
Fit both my Garageboss and Midwest gas cans. Didn't fit my Blitz can. I bought more of these

Good seal on my tanks.

Less prone to split and crack from alternating heat and cold than the original caps.
I like these. The only thing I could see to be improved is that they are too deep for some gas cans. The edge of the cap could bottom out before getting a good seal inside the cap. They just barely fit my MidWest steel cans. They are easy to grip for tightening and removing. The plastic is a better grade for a range of temperatures and far less likely to crack, shrink, or strip. I feel greatly more confident in these than the original caps for transporting and storing gasoline safely. I'll soon buy more for the gas cans at my workplace.

When you need a cap...
Fit our 5-Gallon plastic fuel containers as hoped and do not leak. Over time we sometimes over tighten or the sun and dry weather weakens the plastic and they can crack and start leaking. But these are great replacements and I've not found any that perform better.

Fit metal cans perfectly
These are great caps for the price. Much cheaper than some of the other, maybe a little lacking on the grip but they seal tight. The spout caps on the harbor freight metal cans split in less than a month. These were a perfect leak proof fit with their nice rubber seal
