For reasons explained elsewhere, I would love to replace the 'spout' of about ten Blitz five-gallon plastic portable gasoline containers with a simple gas cap.
I called Blitz, who does not sell an alternative gas can spout - nor would they answer this question.
Do you know what 'threads' these cans use and what 'might' be used to replace the caps that would still handle the 22psi vapor pressure of gasoline & remain air & water tight?
Dumb ass gas cans such as this are mandated here. Real PITA to use and probably result in more gas spillage than old fashioned cans. When I needed a new can a few years ago, I learned that only the so called spill proof cans could be sold here. Doubt if manufacturer would sell you a spout to defeat the mechanism.
Is the threaded ring separate from the actual spout? If so, simple to make a plastic disc to take the place of the spout and seal very well to the top of the container.
IIRC I have bought "Blitz" brand containers in the past, but don't have any anymore due to having to leave them behind every time I've moved (for some reason moving and storage companies don't like dealing with gas cans.) lIRC they came with such a disc, although likely it has been lost over the years. They probably won't sell you replacement spouts or discs now though because of the requirement for the annoying new style nozzles.
I bought an old surplus jerry can while I still could; I hope that I don't end up having to leave that behind.
Non sequitur. Where did I say I was a victim of anything?
Didn't really want to carry gas cans in the same trunk with suitcases, coats, etc. - you know, the stuff you need immediately when you get to your destination. Plus a new gas can is what, $5? Makes far more sense to buy a new gas can at destination and not risk hundreds or thousands of dollars worth of clothes and other essentials.
I meant back before they became hard to get due to the new laws about gas can venting, just like I said.
Not hard. There are almost 700 listings for jerry cans on Ebay right now (including parts like spouts and gaskets).

Aside: Some are even free. About two years ago, while foraging through the neighborhood the night before heavy trash pickup, I spotted one. Zip, into the back of the truck.
I examined it when I got it home. Not only was is more than servicable, it had, stenciled on the bottom in fading white paint:
III Army SEP 44
It's possible my little can helped George Patton relieve the siege at Bastogne!
Well, you can't. CARB has made it illegal to sell anything but the CARB-compliant spouts to fit gas cans. Most other states have followed suit.
Even if you knew what thread it was, you couldn't legally obtain anything to fit it, except a replacement CARB-compliant spout.
The thread is a proprietary thread specific to Blitz's gas cans. I have a couple of Blitz cans, a few Sceptre cans, and one Harbor Freight special. All different threads.
The cap from one brand will cross-thread on to the others because they're close, but unless you use the original cap it leaks like a sieve.
They won't. In fact, when I called Blitz, they couldn't understand 'why' anyone would 'want' to replace the spout.
If you've ever tried to pour five gallons of gas at about chest level, they'd understand why.
You have to use one hand constantly on the spout button (or else it closes), and the other hand has to be holding up the entire five gallon can at about your chest level to pour it out. In addition, you MUST add a hose to the end of the spout because it's too short to fit into any normal tank opening.
The only practical way to use the spout is to simply remove it. But what can I replace it with?
All I need is a cap that fits and holds 22 psi of vapor pressure.
It's not a preoccupation - it's simply a design problem.
Once every couple of months, I drive to the gas station and fill up ten five gallon cans of gasoline. Back at home, I siphon that gasoline into a
55-gallon drum. Then, for the next two months, I use that gasoline to fill two cars and various typical small engine motors. When needed, I return to the gas station, two months thereafter.
NONE of these operations requires the spout.
I simply use the spout as a cap. It's not a big deal but the spout is harder to remove and put back on than a simple cap would be simply because you can't grip it with your entire hand (because the spout is in the way).
So you can only grip it with the tip of your fingers. But it's on pretty tight (air and water tight).
So, it would be a bit easier if I simply replaced the spout with a cap.
Do you have any idea what the threads are and where we can get a cap? I'm sure I'm not the first person who wants to cap a gasoline can nowadays.
I thought it strange that the can only need handle 15 psi (since I'm told the vapor pressure of gasoline is 22 psi) but I guess it's close enough for government work.
Also, it seemed odd that a 'venting port' was allowed - since the whole point of the California gas cans is that there is no longer a separate venting port (it's in the spout now - but that makes the spout nearly useless as fuel flow is severely restricted).
However, the diagram of the threads seemed to be the wierdest feature.
At the top of the threaded neck, the diameter to the outside peak of the threads seems to be 3.400 inches (+- 0.030 inches).
Yet, the last thread of the threaded neck, 1.20 inches later, seems to enlarge that to 3.480 inches (+- 0.030 inches).
And, each thread seems to be 0.016 inches tall.
I wonder why they make the last thread bigger? Is it to make is super air tight? Wouldn't normal threads be just as air tight?
The pitch seems to be 1/4 inch between threads, comprised of a 0.100 inch (+- 0.20 inches) peak, and the rest is a funny shape of 10 degree and 32 degree angles.
Overall, that's a weird shape!
But at least we now know the shape.
I wonder if it has a specific name like most other threads do?
But you gave me an idea. I might be able to pick up those tall metal jerry cans at the army surplus store. I hear you can even pour them straight into the vehicle (or into a 55-gallon drum).
THAT would be an improvement over my siphoning transfer of fuel!
Urgh, mine's like that and it never seems to seal properly.
I used to have a 5-gallon can which came with both a spout (threaded portion was part of the spout and not a separate ring) and a cap.
I've not seen one like that for a long time; maybe they stopped making them because too many people lost the spout while the cap was on (or vice versa).
Maybe I need to find another can like it and get creative with some gas- resistant glue, making myself a single-piece spout and a single-piece cap. cheers
The Jerry Can Paper had a lot of good information.

But it too excluded California: "California residents are no longer allowed to buy any of these jerry cans unless the corresponding spouts meet the new California Air Resources Board (CARB) spill-proof spouts."
Does that mean that if I do buy one of these Jerry cans, I'll have to have them ship it to another state?
The one I have...you unlock the spout, push the spout-in...and it stays open until you release the downwards pressure. I'm not sure if it's the same brand as yours'.
Frank... you are spot on. The new style "enviro-safe" caps literally burst gas into my mower due to the "safety" spring mechanism holding pressure until the can is inverted and forcing the gas out at high pressure... blasting spray and spillage out the to of the tank. I once got a face full of gas on a very hot day because I forgot to release the pressure first. The old style allowed you to simply pour the gas... but apparently that was too logical and easy for the enlightened/woke crowd out there and had to be gutted and regulated.
