Presto makes a 3-piece adjustable weight that can “convert” your Presto Gauge Pressure Canner into a “dual-gauge” pressure canner, like the All-American.
When you buy a new Presto pressure canner, one of the first things old hands will advise you to do is to splurge the 10 to 15 bucks to get this add-on accessory, so you don’t have to watch the gauge.
It’s a 3-piece weight that adjusts easily to 5, 10 and 15 lbs of pressure; the Presto part number is 50332.
This 3-piece weight is only designed for use with a Presto. If you have a different make of pressure canner, you need to look for a weight made specially for that.
The cost is about 13 bucks US (as of spring 2022), and it will change your life. You can order it on Gopresto (US Shipping Only)
The default weight that ships with the Prestos is 15 lbs, which is really only good for people at very high altitudes. For those people, it will be accurate as a rocker in the range of 15 to 16 lbs, but for everyone else, it’s just a counter-weight there to hold all the pressure in, with the added feature of its being able to move should it need to for way over-pressure safety purposes. You have to stand in front of the stove and watch the gauge constantly and fiddle with the burner constantly to maintain the correct pressure.
With the adjustable 3-piece weight, you no longer need to sit in front of the stove watching the gauge like a hawk, or, get your gauge tested yearly. Just adjust the heat so that this weight rocks constantly.
The weight is a 3-piece set: 1 spindle, with 2 detachable rings that stack on the spindle. The spindle by itself is 5 lbs weight. Each ring is an additional 5 lbs. So if put 1 ring on the spindle, it will be 10 lbs. With both rings on, it will be 15 lbs.
To detach the weights; you just pull up on a ring. They are somewhat snug at first but will come off; just pull up. To put back on, just set a ring over the spindle and press it down.
The spindle has a black wood knob that screws off, but you really don’t need to.
It rocks gently and constantly while the machine is use to release excess pressure.
This weight effectively keeps the machine at ½ lb or a lb over the pressure target, because what it does is release excess pressure over the amount selected (by the rings.) So when you have 10 lbs indicated on the weight, the machine will actually reach 10.5 or 11 lbs, at which point this rocker releases the excess pressure.
This 3-piece weight works with more current models of presto; it won’t work with many of the older models of Presto. [ The issue with older Presto models is that it won’t fit the older design of the vent pipe. And the vent pipe that would fit it, can have different size screw threads from the older canner lids, so that’s a no go, too. ]
For instance, it will work with:
- 16 quart gauge model (01755);
- 16 quart weight model (01745);
- 18 quart gauge model (01751);
- 22 quart gauge model (017800x);
- 23 quart gauge model (01781);
- 23 quart gauge induction-compatible model (01784).
When you get the 3-piece adjustable weight, simply take the 15 lb weight that came with the machine, file it away in a drawer, and use the adjustable one in its place over top the steam vent. Have the right number of rings on for your altitude. Remember, the spindle and handle itself counts as the first 5 pounds.
The rocker weight doesn’t screw onto the machine top; it just rests on: it has to be free moving to rock.
You just ignore the gauge completely and depend on the weight alone. The gauge just becomes a handy visual reminder or backup check (that may or may not be accurate as time goes by — note that in the insert that comes with the weight, Presto does say, “do not compare or rely on the dial gauge.”)
The regulator begins to rock “when the selected pressure is reached inside the canner. The heat should be adjusted to keep the weight rocking gently throughout the entire process. You learn to trust the sound of the weights.
You don’t want the weight to rock with violent, steam-engine rocking. That is a waste of energy in terms of money, but in terms of processing it can mean that you will run out of water inside the canner way too soon and run into pressure changes that cause liquid loss in your jars. If the heat source is not sufficient, it will stop rocking and you need to increase heat *and* start processing time all over again from the start of the time. [1] National Center for Home Food Preservation Self Study Course. Module 4. Canning Low Acid Foods: Dial Gauge Canners. Accessed March 2015. You want a very gentle, steady rocking. As long as it is rocking gently you have the correct pressure and temperature. So lower the heat as far as you can go while still maintaining that gentle rocking. It’s more energy efficient, and you’ll get a better, more efficient processing with no worries about boiling the water dry.
This video is from Presto, showing an optimal rock.
For higher altitude people, the decision to use a weight can be problematic. Your altitude may only require 12 lbs pressure, but the weights only allow an increase over that of 15 lbs. Some people feel that can result in over processing, and for that reason they prefer to use and watch a gauge which can deliver 12 lbs.
Summary
We have not heard of anyone regretting getting the 3 piece; the only regret that seems to ever be heard is that they didn’t get it right at the very start with the machine. If anything, you’ll hear complaints of people wondering why on earth it isn’t included with the canner, even if Presto had to charge a few dollars extra.
If you treat yourself to one thing this year, we’d suggest this be on the consideration list.
Again, the Presto part number for their 3-piece weight is: 50332.
Good luck and happy rocking.
Here’s an Amazon link. Amazon links change over time and they don’t give anyone any notice. Make sure you buy the 3-piece one with Presto part number 50332. Ask someone on Amazon if you have to before buying, and though price varies by phase of the moon on Amazon, you should never have to pay more than 15 to 30 dollars (depending on your country) for it at the very very most! If you see it costing more than that, keep searching, cheaper will turn up.

As of April 2023, Presto representatives say that the three piece weights on Amazon are NOT the same as the three piece weights directly from presto’s manufacturer. They are significantly lighter and presto has said they cannot guarantee the safety of items processed with these weights. I’d remove your affiliate link ASAP.

It’s actually very easy to get any pressure greater than 5 psi with this set.
The 50332 which I received from Amazon, made by Presto, is 83 grams for 15 psi. The weight that came with my 23qt presto is 86 grams, which gives average 5.7 grams per psi.
Just go to the Home Depot, buy 1 foot of a thick bare copper wire, cut off an inch and weigh it out. Now if you need 12 psi for example, just cut off 11.4 grams length of wire, make a ring and put it on top of the 10 psi weight.
Example – your results will be different!!! Depends on the wire’s gauge!
1 inch – 4.2 grams
1 psi = 5.7/4.2 = ~ 1 1/3 ” of wire.

I live at an altitude of 2162 Ft above sea level. According to guides lines, using the presto 23 qt canner I need 12 PSI. Regulators come in increments of 5-10-15 psi. Has anyone heard of a place that rings that are increments of 1-3-6 that could interchange with the 5-10-15 giving variable pressure weights?

I ordered this regulator jiggle but for my older model of presto canner. Fingers crossed it will fit the 0175003 model. If not I have a friend that just bought the 23 quart and I will give it to her. My juggler is only for 15 psi and my jiggler never rocks as I have 11 psi recipes 😪

I have a large presto pressure canner tall enough to put quart jars in with the lid on. I got the triple weighted rocker from Amazon it was about 25 bucks, the 15 lb. rocker that ships with the canner is too heavy for when just 10 lb. is required. Excellent deal, came in 3 days. 5 lb runs at 7 lb, 10 lb runs at 11 to 12 lb. I live at 88 ft above sea level, I canned pint jars of roast beef this week, 75 minutes…perfect!

where can i order from beside Amazon? site says unavailable
Colby Curtis
So on Presto website it says it’s compatible with 23 q 1782 but doesn’t list the 1781 which I have. But on this website they say it will work. Can anyone confirm this will work on my 23q 1781 model with the gauge in the center and the weight offset from the center?

I have a question about testing the dial gauge on a Presto canner: If the default weight is set to jiggle at 15 pounds (as this article explains), wouldn’t it be a reasonable test of the dial gauge to simply run the canner up to where the weight starts jiggling, then read the gauge? If it’s 15 pounds, that would indicate an accurate dial gauge, correct? I ask because there is a lot of talk online about getting gauges tested, and I suppose I should do so — but this seems like an easy at-home test method that would save me the trouble of shipping the gauge to the company’s headquarters. Thanks.
Kim
I totally agree with this. There’s no arguing with the physics behind it. When the 15 pound weight start to jiggle, read your gauge and that’s your canner calibrated, simple as that. If the gauge reads 16 psi while testing, you need to hold +1 psi above what pressure the recipe calls for. If the gauge reads 14 psi while testing, hold -1 psi below what pressure the recipe calls for. Can’t see why this isn’t the normal way of doing it at home?

OMG! Just found this blog a week ago and ordered my weighted regulator right away and I love it!
Cheryl Latschaw
I have a 17 quart Presto canner model #0175003 and another model *0175006, can this weight be used with these canners?
Healthy Canning
Hi Cheryl, contact Presto’s excellent customer service, and ask them. You can contact them by email, or phone: https://www.gopresto.com/information/feedback.php

How do you purchase this 3 piece weight regulator for a 23 presto canner. Ours is # 01781 presto canner.
Healthy Canning
One place you can get it is Amazon. Your local hardware store may be willing / able to source it for you as well.
Robert Wade
Fred, if you read the article above they give some of the common presto canners that the weighted gauge will work with. they DO list the 01781 pressure canner in that list. In case you missed it, the weighted gauge is Presto #50332…
Ray
I’m looking to ship a 23 quart pressure canner over seas and I don’t know how much it weighs. Want to figure out the cost
Healthy Canning
There will be two weights: the canner by itself and the canner with packaging. You’ll want the canner with packaging weight. I don’t know that, sorry. Maybe Presto will; try them directly.
Sue
How do I figure out what model Preto Canner I have? I bought it off craigslist without the box or papers. I’m missing the regulator as well and ran into your site. I’d be thrilled if I could exchange the guage for weights! I’m new to canning and haven’t tried it yet.
Healthy Canning
Can you email a mobile phone pic please to [email protected] or post it to https://www.facebook.com/healthycanning ? Thanks :}
Sue
Thank you

Hi Sue. on my Presto Pressure cooker the model is stamped into the bottom of the pot, in the centre. It is not a label. It is stamped right into the metal and can be easily overlooked without a close inspection. If you see a series of numbers just search Google with it. You should see pictures of your pressure cooker if in fact it is the model number… Good luck!
D
Look on the bottom of the canner. The model number should be stamped in the center.
Healthy Canning
We can’t see a model number on the bottom of either the current 16 quart or the current 23 quart.
Richard Gunn
The model # will either be stamped on the bottom of the canner or on the outside under the handle.
Lorraine
The model number is on the side of the canner under the handle.
Carla
How long does it take for the regulator to start rocking? I’ve had mine on for almost 35 minutes and the regulator is not budging
Healthy Canning
Hi Carla, you’ll get faster replies, and help from more people, over on our facebook page. https://www.facebook.com/healthycanning . Over there, can you say what make and model you have exactly, what type of stove, and what type of burner you have it on?
