No I haven't @Tricky Micky, I have used teflon coated sous vide magnets as they are food safe. They feel very strong if you try to separate them but through the wall of the kegmenter they do not work. I guess that it is possible that the neodymium magnets could work (I just read that 304 SS will pass a magnetic flux) but when you feel the loss of magnetic flux with the magnets that I have tried though the kegmenter I am doubtfull. I should try out the neodymium magnets as they are fairly inexpensive.

Let’s call it 830mm bottom to top @kmar92

Perhaps that is the overall height of the All Rounder plus the hop bong? My 58l kegmenter is only 630mm high so the hop bong would be higher by itself, than the kegmenter.

It really depends on what grade of SS 304 you are getting with those, and where it’s made 🤷‍♂️

All Rounder plus Hop Bong equates to 830mm.

Thanks @Red devil 44, that would probably fit in my ferment fridge then. I am guessing a little and estimating that my 58L kegmenter with hop bong would be about 910mm high and my ferment fridge will fit about 1200mm of height.

Without wanting to start a massive debate,  after spending about 20 years as a sheetmetal worker who specialised in manufacture of food grade equipment, please take it from me 304 Stainless Steel is classified as Austenitic (meaning its chemical make up prevents this type of steel from being hardened by heat treatment and it is essentially non-magnetic).
Generally, stainless steel grades that start with a 4 in their grade (eg; 410, 420 and 440) are known as martensitic stainless steels. This type of stainless steel is magnetic primarily because it contains large quantities of ferrite in its chemical composition, which is a compound of iron and other elements. The grades used for commercial tableware and fastener industries (Eg; 18/8 and 18/10) are also known to be magnetic.

So simply, if an item is truly made from the grade 304 stainless steel, it should not be magnetic.

(C = Carbon,  Si = Silicon, Mn = Manganese, P = Phosphorus, Cr = Chromium, and Ni = Nickle)

Great analysis @Triple B Brewing 👍👍

The spunding valve is closed I'll let it build up under its own steam to 11 or 12psi

Keep a close eye on it.  The pressure can build up awfully quick.  And when I say awfully, that describes what it would look like if the FV ruptured.

I filled 6 kegs to 15 psi from the off gassing coming from a fermentation on its second day.  Imagine 90+ psi in one of those PET fermenters.
