DIY Spunding Valve

dmaraio · 07-31-2009, 12:21 AM

Just got the parts today, it is only rough fit but it looks like its going to work well.

Got all parts from McMaster, including the item numbers here:

48935K25 Pressure Relief Valve 1/4" NPT Male, 0-20 PSI
4089K23 1/4" NPT Male Center Back, 0 - 60 PSI Gauge
4429K223 Low-Pressure Brass Threaded Pipe Fitting 1/4" X 1/8" X 1/4"
50675K161 Brass 37 Degree Flared Tube Fitting Adapter for 1/4" Tube OD X 1/8" NPT Male Pipe

Total cost was about $35, that includes shipping. The relief valve only goes to 20psi, on hindsight I should have gotten something that is capable of up to 40 if I want to carbonate outside of fridge, I can always swap in another valve

Edit:

I found an alternative valve that will allow you to go between 25-200 PSI. This would be great for doing a highly carbonated ale, think Hefeweiss.

OK. I had no idea what a spunding valve was until your post. For anyone else who had no idea there is a link below. Seems like a good way to save time allowing carbonation for keggers. Is this what you are using it for (looks like it from the flare fitting)? Didn't know if there was more than one use for it.

P.S. How much did the pressure gauge cost from McMaster? (Ball park figure)

You'd definitely want to grab a pressure gauge off Ebay at a hefty discount.

The gauge was $10.28, you could probably do better. It seems like its made well enough. The housing of it is plastic and could break if you stepped on it or dropped it thought.

And yes, the fitting is 1/4 flare. I will be connecting this to a flare, ball-lock gas disconnect.

Thanks for the pricing and info. I was just curious for my kegging needs in the near future.

I am not sure how I can connect this to my sanke coupler. Does the size flare fitting on the parts list fit the flare nut already on a standard "D" sanke keg coupler?

Thanks.
