Didn't actually receive them, I canceled and bought them elsewhere but they are the same. Revain may remove this review if it chooses to do so. I never use a nozzle on my glasses, that's all I really need and they work perfectly. Fits perfectly and doesn't leak. They only say for 5 gallon cans I don't know why maybe the law or something but they fit 2.5 gallon cans and they don't leak. I think they are made by the company that made the cans so they work fine. If they are leaking, just know that there is an o-ring in the cap that can be replaced. Not sure if Revain has it, but if NoSpill has it. Keep in mind that while nozzles do not have a built in pressure relief tube, they do need to relieve pressure from time to time.
