Well at least we've figured everything out and you can get the right part without doing any modifications to your lid. For the time being you should try the weight. Put some Teflon tape on the threads. Did you get the weight cleaned up? At the very least you can order a replacement.

one down, one to go.  this is the 941


my metal working buddy had a tap, could still not fit it in the 921.  had to order another lid :oldman2:

but at least i got the 941 hooked up.  got it up to 20PSI, then flipped shit, cut the heat, and ran out of the house to smoke.  came back, and it was in one piece still :blazed:

thanks for the help tahoe, eno, and J.  this is probably going to be one of the best purchases i made all year.  for less than $30, i don't know why everyone doesn't do it.

So...is there a known incompatibility with this part and the AA model 921, because that's the model I own and I also had a problem.

AFAIK, my 921 is an older model, and it will not fit.
this 941 was purchased in 2012, and the stop cock screwed right in w/o resistance.

thats my best guess :shrug:

Blinding leaf. Good to here that you are good to go. I think I will add buying a tap to the original post. Some might need to cut new threads and some might need to clean out threads.

I do know that the vent is not made by aa. They are an aluminum foundry. The valve might not be aa specific either. There are plenty of 1/8th 5-200 steam blow out valve's on the market. The one for the aa is made by Kingston. The psi could be changed on the valve of you spun the inside cartridge. Although there is a dimple on the side which is supposed to keep it from spinning.
Look close and read the writing. Kingston mfg 11/14, 122 wemp (might be part number) 1/8 npt, set 26psi.
Here is the dimple that keeps us from tampering with it.

When I get some more time on my hands I will remove and plug up the safety valve. Then hook it up to an air compressor and pump it up until the blow out plug goes. I will make a vid with the go pro. It might not be that impressive because it will lack the surprise and 275 degree steam. But it will be nice to have an idea of what happens.

Aa says that they are both 1/8th national pipe thread/male pipe thread. I think a tap will still be a good idea with this upgrade.
Here is the reply from aa

Good morning,

 

You are correct they are 1/8 NPT. 

 

Thank you,

just an FYI to anyone who cares, the 941 pulled a vacuum and kept it for 24 hours, and it was not at full capacity. only two grain bags @ 7 lbs each.  i do not have the extension pipe thing that goes down.

Liar! You need the tube for vacuum!!!!! :ducklol:

A new stopcock was delivered to my house today for my oldschool 941. I'll try to get it installed and tested when I get home after work. This is a pretty old 941, I have no idea when it was made, but it has the older label.

How much did the stopcock screw into your newer 941? They only thread in a few turns on my newer 921('12 or '13) and 930('15).

I need to work out a kink with my 930. It's not pulling vacuum, but I'm certain its the blow out plug, it makes some hissing and bubbling sounds during operation. I'm thinking that a little vaseline around the contact points of the BOP and lid may solve the issue. Might be the same with my 941, so I may give that a whirl before before replacing the stopcock. Though I still want to replace the stopcock, since the newer ones hold a little more pressure. The stock one on my 941 releases at ~22psi.

oh cool, do u have one of the gauges that reads negative pressure??  i've always wanted to see those.

it screwed into my 941 actually a lot.  i'd guess about 6 turns with my fingers, and another 2-3 with a wrench.

good luck on the older model man.  i was thinking, since i ordered a new lid for the 921, but the physical body of the PC is still the older model….u think it will fit ok, metal to metal seal wise?  i hope they didn't alter that at least.

Blinding leaf, I can switch lids on my 921 and 25x. The new lid will fit. Why did you have to go with a full lid replacement?

So speaking of holding negative pressure. What are the advantages of of being able to do this. The pc sucks in a bunch of dirty air when you pull the lever. Btw, I probably knew the answer, it's just not coming to mind

I could be wrong, but my understanding was that bacteria and mold are killed not only by the change in temperature but that their cell membranes lyse due to the change in pressure.

No I just have a stock gauge. Swapping it out for a gauge that shows a vacuum range wouldn't be that hard. The stock gauge indicates vacuum. Take a look at the gauge under no pressure. The needle sits at 0psi, but there is a peg a couple millimeters below the arm. Under vacuum the gauge arm will pull down and rest on the peg. When you release vacuum you can watch the needle raise back to 0.

The lid should fit fine. My 921 & 930 lids are interchangeable. You could still salvage the old lid, couldn't you? If the threads are fucked, you could drill it out and retap it for a larger size, and use an adapter to install the stopcock. I would imagine your buddy with the metal shop probably could do that.

A regular PC will suck in dirty air on cool down through the imperfect vent\weight seal. Anything without a filter on it in your pc could be at risk. Having the chamber pull vacuum until you release it allows you to open it and suck in clean air in aseptic conditions without the cooker having to be moved to aseptic conditions while still under positive pressure and hot.

I did not install the new stopcock today. It was broken, the deflector shield is loose. :frown: I will post pics tomorrow.

The lid is definitely salvageable. Do not buy a new one. There are a few really easy options. Assuming we are talking screwed up threads. Even with bad threads you should be able to tap it with the 1/8npt. Pipe threads are tapered, so the valve gets tighter the further it's screwed in.

Option two. Weld around the hole with appropriate welder. Make hole smaller, tap.

Or drill out to 1/4inch npt. Thread in a reducer and then go from there.

All three options are safe. You will not weaken an aa nor blow one up.

Welding aluminum?...mmmm I'd be concerned.  That's much easier said than properly done.  A better idea is to drill and tap the boogered hole to accept a stainless steel bolt and plug that hole with the bolt.  Then drill and tap the lid in a new, convenient place for the valve.

Welding aluminum is easy. I would not randomly drill holes in the pressure cooker. The pressure cooker is cast with thicker areas on the lid to accept milling and drilling.

tahoe, no worries.  i had a metal working friend look at it, he mentioned one of the options u did, but i felt safer ordering a new one.  the tap didn't work, but i really think its cause this is an old PC man, i think 00-01, but i don't remember the seller so can't know for sure.

would have been cool to weld i guess.  i've done MIG welding with angle iron, but thats about it.

That sucks you have to order a new lid. Does anyone here know how to read the serial number to tell when the PC was made? The serial number on my 25x is 0014156. Does that mean it was made in 2000?
