FNG here. I found this thread while looking for tech data on the AA PC/Sterilizer. Glad to see some free thinkers actually working on their equipment.

Let me add a couple tid bits of mechanical knowledge.

Those petcocks that don't fit have too big of a diameter. Those pipe threads are tapered, the farther you thread them the smaller they get. You need a 1/8npt die to do that, as opposed to a tap for holes. Poorly done QC.

Also, those newer petcocks with the deflector shields are multi-piece. The bottom piece, under the deflector, should be screwed in and out separately, so the torque doesn't bust the 'legs'.

And the flexible spiral vent tube in the sterilizers is to let the air out from tyhe bottom. Steam is lighter than air, and rises to the top. Air vs steam is discussed in a 'getting started' FAQ. If you don't have the flexi vent tube, it will just take a couple extra minutes of 'exhausting' to get the air out.

Did the guys who had broken jars us a bottom screen? Holding stuff up off the bottom makes for more even heating, less irregular expansion.

Anyways, I want to do the reverse adaptation. I stole a 1915x from eBay for $80 delivered. I want to pressure fry chicken, KFC style. Only full size chickens, not the hatchlings they sell by the piece instead of the pound. Anybody willing to send me their leftovers parts?

Good thing for us that all the sheeple have been herded over to Facebook.

bumping this to brag about completing this upgrade myself. deffo worth the effort.

even with teflon tape, screwing the stopcock into the lid was pretty awful, because unscrewing the old part took some of the aluminum threads with it. always be cautious screwing steel into aluminum. i opted to spring for the cheapest 1/8" tapered NPT tap i could find to recut the threads, which made a major improvement.

first run, i bumped into the lower range of pressure release, the valve hissed a little around 25psi, and got louder up to around 28psi. thankfully, the blowout plug didn't give up.

using less water means this thing got up to temperature so much faster, and i didn't realize just how loud the hissing weight mech really was. so nice not to hear it.

there's no flowhood in my near future, but i want to run some bags. so i spec'd a design for an automatic inline intake filter. if it ever gets built, i'll post it here.

should is subjective. tapered threads are what they are explicitly to address the question: how to create pipe joints which hold pressure without any kind of additional seals or sealant? but dissimilar metals under elevated temperature and pressure sometimes like to chemically stick themselves together, which explains my threads tearing out.

in short, if your valve holds pressure, and you have no plans to ever remove it, it's all good. if you have plans to remove it or are accident prone and can foresee breaking the thing off, a barrier of some kind, like teflon tape or antisieze paste would be wise. if it's been ages and dozens of pc runs since you installed it, any attempt to remove the valve now might well break it off. probably not worth the risk.

I have found a place to get the All American pressure canners at great prices for a limited time. I have posted it in the Marketplace here.

I guess I don't need to explain the deals to people following this thread. It is a great chance for anyone who is into this hobby to get an All American for a great price.

Hello all, I am new here. I bought used PC, it comes with two vents which can be changed - one for 8 PSI, other for 17 PSI. Can anyone tell me how to know which one is correct one? Because they look identical. I don't have papers for PC. Also PC has safety vent, maybe it is all automatic cooking? So when vent goes to 17 PSI, safety vent starts steaming?

Buy something modern those old off brand PCs probably have no replacement parts and without having some basic mechanical and engineering know how you're not going to be able to find parts you could use as replacements. Especially if they use gaskets you might have a hard time finding a replacement for those on a off brand model.

As for which one is which for the psi thing if you choose to go this route. The one that's harder to push on and open is the higher PSI one. Or put them both on and try to test runs you'll figure out which one holds more pressure as it takes longer to get it to pop open.

Well it took me a few days to read but this has been a very interesting thread, thanks for all the info.

I am new to the hobby and hoping someone can look at the pics of my PC and tell me whether it is likely to achieve the same result as what the modification does, assuming it’s all in good working order with no leaks or broken parts??

Thanks for the reply Jack. From that I’m assuming you mean we probably don’t need to buy any of the new parts listed in this post and, that this PC should basically perform as a steriliser just as it is??

It’s an old used model but it seems to be in good condition. We are new to this and have not tested it yet so don’t know for sure. Shipping from USA down to here is a real ball tearer to be honest, almost making a reasonable purchase unviable, so we are hoping to spend nothing more on it, if what we have looks ok.

ha, that does look like some shit i'd do.

r3d, if i understand it correctly, that lid has the classic version of the stopcock, meaning you bring it up to boil with that doodad open, vent for several minutes before shutting it. it will not stop pressurizing the way a jiggler weight would, so you have to mind the gauge.

Thanks again Jack.

So if the gauge is cactus, we could be in trouble? Sounds daunting.

I will be closely babysitting the gas burner level, but assumed the 4 small holes around the perimeter of the petcock body would also be for pressure relief no?

Perhaps I should use a portable LPG gas burner outside, instead of in our kitchen where the Mrs will probably shoot me if I blow it up.

Hopefully the old overpressure plug is in good order too then, as I don’t know whether they ever need servicing or replacing over time, I can’t find much info on this particular model nor the parts. I was hoping the OP would also weigh in on this one, as he posted a similar pic to this model.

This may or may not be the place for this but enough people on this thread have AAs so I'm gonna ask. 

I just picked up a used AA 921 with the old style petcock!  I'm elated!  But then I pressurized it and I have some concerns.

I've got some bubbling around the seal.  I cleaned it up with a scotchbrite pad after using iso and paper towels as pasty recommended in a thread before the first use.  Then upon seeing it still bubbling, I took some 0000 steel wool to it as WAFCO recommends and I've seen many other people around here mentioning.  However I'm still seeing bubbling.

It does maintain pressure and pulls a vacuum for at least 12 hours when it cools, but I'm disconcerted about  regular use with the seal bubbling.  It also pops and dings sometimes during heatup and cooldown.

Yes I'm using petroleum jelly around the seal. 

Am I right to be concerned?  Should I take any other steps?  I've seen 000 steel wool recommended but I'm nervous about putting scratches in the seal that could potentially compromise it.  RE: the use of the 0000 steel wool, I was only mildly aggressive with scrubbing at it and made sure to use full round strokes so as not to wear down one area disproportionately.

odds are quite low you'll blow anything up. the petcock should vent somewhat before the relief opens. the relief is there in case the petcock gets clogged. my new school petcock, for instance, started spitting around 25psig or so. old springs don't get stiffer so assuming it worked that way to begin with, it should still work that way. you look to have the lid without the over pressure plug. it's old enough to have the safety relief valve. meaning, if it blows, you have a mess, but you don't have to find the plug.

hobbyist, i don't know what's involved in dressing the seal surfaces. if the bubbling is minor, and it holds pressure, i wouldn't worry about it too much. trying to fuck with the surfaces could just as easily make it worse as fix it. have you tried turning the lid 180 on the pot?
the pops and dings, i'm not sure about either, but i think they result from unevenly tightening the lid. i'm sorta compulsive about tightening crosswise, with an even gap, uniformly all the way around. mine does ping occasionally, but not often.

I haven't tried that.  I'll do so. :laugh: 

I was concerned about that very thing which is why I was nervous to mess with the mating surfaces much at all. 

I tested it and my petcock releases at about 26 pounds.  Apparently the old hexagonal shaped metal safety release plug has a lead pellet inside that will melt at 28psi and release pressure.  Since they don't make them anymore I'm gonna really hope that doesn't happen!

As an aside I looked up the melting point of lead and it appears to be above 600* and since I'm pretty sure the PC doesn't get that hot at 28psi, I'm a little confused..    :utterconfusion:
