My units aren't that old at all. '94 and 2003. I bought them used so I don't know the history of whether they were misused/abused or not. The one I remember offhand was around 28 lbs. Remember that I have 2 protection vents, the red one and the metal one with the spring. That's why I believe that I may upgrade to the latest stopcock and try the "over pressure" again.

I bet its actually possible. You can get all the parts to do it. I think you just have to drill the same sized hole into the side by the bottom in the right spot for the heating element power cords. Then from there its just mounting all the hardware to the base from the sterilizer models.

If your current stopcocks pop open at 28psi you don't need to change it.

Have you seen anyone try this before? It may be worth me giving it a shot, but I'll get a new PC first for that. I'm hoping the holes would seal off correctly, and not leak.

I understand your point Juiceh but I am wondering why I have 2 backups after that. I am glad that I do however.

Induction doesn't work with aluminum pots. Thats what the adapter is for in the second image. The induction cooktop heats the adapter, and the adapter heats the pressure cooker.

Not that I recall. I think every part needed to do it can be purchased though. If I were to do this I would convert my 930 I think. Just because its one of the sizes that you can't get in an electric sterilizer model. Before attempting it I would want to find a maybe broken 25x to take apart and see exactly how its put together.

Just extra redundancy. What sterilizer models do you have? I think I saw that you have a 1925x? I been thinking about getting a 1925x basket to use in my 930 with an air exhaust tube from an 1941x. Is anything put under the basket before use? Like a trivet?

What is the weight limit of the induction cooktop? My next house may not have a stove with enough room to handle the 941 so I've been looking at other heating options just in case. But I'm not sure many induction cooktops can handle the weight of a fully loaded 941.

20 lbs is the "weight limit," but I go over that every time.

Juiceh, I have a 1915x and the 1925x. There are four bulges in the bottom of the baskets that keep the accessory from sitting flat on the bottom of the vessel itself. I'm sure that the 1941x tube will fit in the 930 as they are the same height. I am thinking of getting the basket for my 941 to do the complete conversion.

Edit: I didn't realize this thread was still getting some love. Been busy hunting.

I like the new gauge setup. My reason for posting here has to do with negative pressure also. Anyone else have problems with the release valve sticking shut while holding negative pressure? I have tried to let air into it after it's cooled. I lift the lever and no air sucks in. Even if I do it slowly. So I have had to warm the pc back up and let it build pressure to 0 psi.
Usually I will try to catch it when it's cooling down and open it at 0 psi. Then let it cool the rest of the way with the release valve open.
Check it out. The valve is in the fully open position.

LoL yup, I was gonna post this a few weeks ago. I thought I was going crazy!
It's happened twice to me. I just fuck with the blow out plug in front of the hood and let some air get sucked in there.

I even looked under the vent shield, and the lever was in fact pulling the stop up. So I thought the vent got blocked somehow from the foil covering the one jar in the cooker. But when I opened the PC this is what I saw:

Man. Your pc looks like it's got a bad case of skid marks. Don't let your lady see that. ;-)
What are those marks from. Are you cooking in it also?

I haven't had any trouble with the stopcock sticking. Maybe pulling up on the stopcock to break the seal would work.
So on a sort of related note, I totally fucked up the lid on my 23qt presto which means I'm down a canner and if I actually need to can something I'll have to use the 25x. I noticed that some of the old AA canners have stopcocks on them so I'm wondering if I can get away with canning in the 25x just by switching out the overpressure plug and taking the vent tube off.

Those are from jar lid rings. Been thinking about trying to clean that up. Was gonna try some CLR, but the bottle says not to use on aluminum. A scouring pad \ steel wool would work but takes a bunch of scrubbing that I haven't felt like doing. My 930 has a bunch too.

My old 941 came with an older stopcock. I don't see why you cant use a sterilizer for canning. Just keep the pressure in the range required for the application. Don't bother switching out the plug, but I would remove the tube if your not using the basket. Does the 25x come with a stand to hold stuff above the element without the basket?

The common practice, as mentioned before, is to "tie" up the tube to the top of the lid with a rubber band (I use a large twist tie) to keep it out of the way if you are going to continue to use it for both applications. If using it for a dedicated application, removing it would be safer. I don't trust today's cheap rubber bands for this purpose, especially when high temps are involved.
Nice to see you back Tahoe. Nice pics.

So I was doing some research and I think I found out how the previous owners of my pressure cooker raised the PSI capabilities of the PC.
They say that All American pressure cookers are tested up to 200psi.....which is fine, I'll never try it, but 30 seems fine. maybe 50 even?
Anyhoo, Theres a Nu-Pro (Swagelok) check valve, and a poppet check valve? on my pressure cooker. I found this to kinda clue me in on whats going on BUT I have not found the exact model, but some are adjustable. from the looks of it mine is fixed. http://www.swagelok.com/en/catalog/Valves
 maybe its this one, they don't make a 35psi one and I hit 31 psi while I use it myself so i think its 40psi. Mines SS too, and these are not cheap, at all. Probably a +100 dollar valve http://www.swagelok.com/en/catalog/Product/Detail?part=SS-CHS10MM-40&item=

Nice find! It sure looks like the one on your sterilizer. How do these connect? Looks like they require a tube to be crimped onto or something. Any idea what the other valve is that's in the spot the stock gauge goes?
I see from the sticker on top of the lid that it is a sterilizer model, did you get it with the basket and does it have the air exhaust tube as well?

They are both the same brand, one is a check valve, the one that is directly on the lid, to the best of my knowledge, is a "poppet" check valve.
They are all SS, that valve on the stem probably costed more than I paid for the pressure cooker, lol.
They are are all 3/4 inch pipe fittings. they screw. no crimping. i think it did come with a basket...I can't remember, but the twist knob is an adjustable bleed valve.
I think anyone could safely adjust their All American to run higher than spec, but I couldn't endorse it, proceed at your own risk, lol.
Some of these parts (check valves) are $100 and up in SS but you can find them in brass cheaper, and then there's used pieces too. I'd buy used.
it hink I see what you mean by crimping, The check valve had all male endings the piece of the post in the middle was a male so they made a small section of pipe with two females to connect.
