Description
 
This spunding assembly includes everything you see in the photo (if you select Ball Lock in the dropdown)

The assembly includes the following:
Threaded 1/4" NPT Tee (304 Stainless Steel)
0-30 PSI Gauge threaded into one port.
Adjustable PRV (Pressure Relief Valve), Brass with stainless poppit and spring. This can be completely disassembled for cleaning.

Options for the remaining "tank connection" port:
Ball Lock or Pin Lock Gas QD, or Sanke Tailpiece (for connection to a Sanke coupler)

Note that if you select SANKE, the input to the spunding will be a tailpiece and beer nut but it does NOT include a keg coupler. If you are connecting to a conical fermenter, the 1.5" TC option would make sense.



Uses? Measuring carbonation level in a keg already carbonated (measure temp, measure constant pressure over an hour, refer to carbonation chart), Vent a keg that is naturally carbonating with priming sugar to avoid overcarbonation, pressure ferment in a corny (the true meaning of spunding).


We've had a lot of questions about how to use this device. First, please be aware that we don't have a lot of experience using spunding for pressure ferments but here are a few notes. You can use this device to check and/or vent a keg that has had the gas source disconnected. If you want to just use it to check pressure, turn the PRV all the way clockwise so that it doesn't vent and then connect to the keg's gas post. If the pressure is higher than you wanted, turn the PRV counterclockwise to allow venting.

In order to set the PRV pressure for venting during fermentation, it's best to pressurize the keg first to just over your desired vent pressure, rotate the PRV clockwise nearly all the way and then attach the spunding valve to the keg. Rotate the knob counter-clockwise slowly until it begins venting. Find the spot where it vents down to your desired pressure and then stops. To check that you've set it properly, remove the spunding, repressurize the keg to a few PSI above your set pressure and then reattach the spunding to watch for appropriate pressure venting.

This process sounds tedious but gets much easier after you've done it once or twice. You can also save gas by connecting the spunding directly to a gas source using our ball lock jumper post. If you don't have a CO2 source, it would be best to start using the spunding until after fermentation has become quite active.
That way it will be building pressure while you are working on adjusting the knob

Warning:We recommend using a corny keg with a lid mounted overpressure vent in ADDITION to using the spunding. It's always better to have redundant overpressure protection when fermenting in a pressure vessel. It is safer to use an open blowoff device for the front end of a fermentation and then switch to spunding when krausen has subsided.

Easy to use and exactly what was needed. I move it around between Keg and fermenters.

2 of 5 Leaky Valve June 3, 2021
Reviewer: Scott Walker from Rockford, IL United States  
I also have problems with the valve slowly leaking. It does work, but you need to monitor it every 6 hours or so, since it slowly leaks and you need to adjust the valve to compensate for the leaking

1 of 5 Leaky and no support May 3, 2021
Reviewer: Justin from Utah  
No matter what I did I could not get this to properly hold pressure.  Working with support they gave me a couple suggestions on cleaning/lubricating the poppet gasket, but in the end it just didn't work.  Trying to get further support or some sort of replacement from these guys has so far gone no where.  After weeks of waiting it appears my follow up emails are just getting ignored.

I bought this so I could ferment / naturally carbonte / serve in the same keg.

To set the valve up, I filled my keg with water, hooked up to CO2, and put the spunding valve on the Out post.  Pressurized the keg and slowly turned the knob until the gauge read the pressure I wanted for naturally carbonating in my 65 degree basement (~23psi).

Racked straight from my brew pot into the keg, pitched yeast, closed keg, and attached the spunding valve to the Out post.  Replaced the dip tube with a floating one to keep trub out of the served beer.

This was an English Dark Mild using S-04.  After about 6 days, it was carbonated with no problem.  I took off the spunding valve, hooked it up to serving pressure CO2 (10psi), and put it in the kegerator.  

Worked extremely well and saved me a bunch of work / sanitizing / cleaning by doing everything in the same keg.  Also saved at least a day of waiting for it to carbonate, since the fermentation naturally carbonated the keg for me.
