Presto 85-729 Pressure Canner Steam Gauge

Works great

it fixed the problem

Broke mine this was a perfect price without the shipping cost

Used to replace my old gauge. Came in good time and fit well.

Nice item. I used mine to measure psi in a homemade low pressure tank that I made for mushroom cultivation. I only allow the low pressure tank to reach 3 psi before a pressure relief valve relieves the pressure. This pressure gauge does a good job to measure even the little bit of psi that is obtained inside of my homemade 55 gal steel drum/low pressure pasteurizing/sterilizing tank. I did have to buy a special little nut with fine threads for it. First I checked Lowes and they were currently not carrying the item so i went to a local hard ware store named Mead's Hardware and they carried it, but they carry a lot of variety of things. I forgot the size nut it was. You may have to go to lowes or some place to get the measure for the nut and then call around your area to see who is carrying the nut. I don't know how it installs into a pressure cooker. It comes with a rubber thing that you see in the picture. I thought about just using that to install the gauge but it really seemed like it wouldn't be enough to hold the gauge. i wouldn't even try it to see. I would actually bet money that it wouldn't. But I'm no expert, so I bought the nut to be safe. This item was packaged very well. I BELIEVE YOU MAY HAVE TO BUY A NUT FOR THIS ITEM.

It was weird not using a nut to tighten it but after I looked up some direction online I saw it just fit into the supplied rubber grommet.

I drilled a 1/2 inch hole in cooker lid. Installed grommet. Screwed gauge into grommet. Worked well. Found that my 15# weight only gave me 12 to 13 pounds pressure. (at 7300 feet elevation). After adding pressure gauge I had to add about 1 1/2 inches of copper tubing on top of weight. This gave me 16# pressure. The additional weight also gave me a more steady pressure. Could not reach a 240 degree temperature at 12 to 13 pounds. That's my thought.

I had an older 23 quart Presto Pressure canner. The gauge was failing. This the replacement. Works perfectly.

ok

The gauge works great and fits fine. The only issue is that it did not come with a nut to secure it to the lid of the canner. My old gauge had a nut but with a different thread. So I had to go and find the right one and purchase the nut so I could use the canner. It was the only thing missing from the package. No idea why they wouldn’t include it.
