No leaks.
They fit standard cans. Tight seal no leaks. Finally a lid that won't leak when i go get gas for the mower.

Thick quality material
Sealed well even after the sun hit and built pressure. I use them for bad gas to take to hazardous waste and a leaky nozzle is not needed in the mix.

Better for storage, indirectly better for pouring
Compared to spouts with caps on the tip, these provide a much more reliable seal and are eliminate the awkward spout for storing gas in 5 gallon cans. Using them for storage also might free up useful, old-style gas can spout, if you have one (spouts that actually let gas come out of a gas can without a hassle --- remember those?) for use at the moment of pouring. This in turn saves untold aggravation, a fair amount of spilled gas, the constant need for a third hand, and considerable arm strain by not having to deal with today's modern, "improved" spouts, while holding a heavy gas can that has the handles in the wrong place in the air while the new spouts take longer and longer to fill whatever it is that still requires gas. This after you get flow started, hopefully that without spilling gas all over the place. Highly recommended!

Will not fit all 5 gallon cans
Doesn’t fit all sizes of cans but fine for the sizes that it does fit

Not what is represented
This product was supposed to include a pouring spout. It wasn’t included. Do not buy. Also the caps aren’t universal, only fit one type of fuel jug

No leaking
Makes diesel fuel cans much easier to refill. No rubber gasket or screw down filling device to get in the way. Seals tight without leakage.

Be patient
Don’t seal well on my harbor freight Midwest cans. A real PIA. Can’t tighten down too much. There is a sweet spot if you get the rubber gasket just so and don’t over tighten.
