Inert bag method making sure I have my ducks in a row

[hellocana]

I'm planning on doing this method in the next month, I would do it sooner if my license wasn't suspended lol. Just looking to make sure I have everything in order. I'm also planning on going in one go at a hotel. I can't really do testing ahead of time but if anything I can do testing right before or pass on the testing all together. I've hyperlinked the products below

Tank:
I can get a nitrogen tank which measures to 24 inches. Based on what I'm seeing, that should be more than the 600L required. It's the 11AL on the chart below and %99.9+ nitrogen according to safety data sheet. Just to make sure is the tank big enough?


Tank Items:

Harris flow meter regulator. This is for Argon, but for conversion for nitrogen flow should be 26 CFT. Is this correct?
Nut and nipple Nut is 5/8" and Nipple is for 1/4" rose. Question: does the nipple screw in to the nut by the threading?
Flexbible PVC tubing 1/4" it says soft water tube, should that be okay?
Tube cutter to shorten the tube
Hose clamp to tighten around the nipple
Wrench to tighten the bolts



Bag:

Reynolds oven bag : Measures 19 x 23 inches
Elastic cord and cord lock to go tighten the bag
Scissors to cut the cord
Micropourose surgical tape on top part of bag and to seal bottom



Thick oven gloves to protect my hands, safety strap to keep cylinder in place

Any insights would be appreciated!

I got the 11 AL and it was 55 scf which was 1.53m3 in volume which is 1,530 Liters weighing 22.6 pounds, which is more than enough.

As for the nitrogen conversion with the argon I reference this post https://www.sanctioned-suicide.net/...ert-gas-megathread.8393/page-176#post-2711877

No the nipple doesn't screw it, it just rests in the nut, a perfect fit. Make sure you also test this part of your setup for leaks with soapy water. (I use dish soap, some use windex)

As for your tubing, I used a similar if not the exact same hose with 10mm OD and it left a big gap that when I tested it on my dummy head, didn't inflate the bag well.

However I got oxygen tubing, and it did inflate the bag well, and didn't leave a huge gap. So I recommend oxygen tubing.

I recommend these turkey bags: https://www.amazon.ca/dp/B075BQYDFV?ref=ppx_yo2ov_dt_b_fed_asin_title
Also confirm the size of the exit bag, a little big isn't a huge deal but too small won't work.

Thanks for the response! If the nipple doesnt screw in wouldn't it just blow out?

Couple other questions:

I can't seem to find out the size of the oxygen tubing, looks like it's all one size. Are you supposed to cut off the end tips and just use the tubing or can those ends fit on the nipple?
According to the nut and nipple, I'm seeing that it says "max 200 PSI".. will that not work? Since i assume the PSI is going way higher than that
And would those two products fit each other? The regulator and nut/nipple, there is no size indication on the description of the regulator, I just see that they're "frequently bought together"

No If the nipple doesn't screw in it, it doesn't blow out, those two pieces will just fit together securely. You will see when you get it, you put the nipple into the nut.

I got that exact same oxygen tubing, no don't cut the connecter off! That's the part that goes on the nipple, but you can cut the other end off to cut the tubing to the desired size. The connector will have trouble going on, you may need to heat it up with some hot water, and push it onto the nipple until the second ridge. Then it should be fine.

From chatgpt:

"If your nut and nipple are only rated for 200 psi, you cannot connect them directly to the tank without a pressure regulator. The regulator will step that high cylinder pressure down to something safe, such as 200 psi or less, before it reaches your fitting." 15 LPM shouldn't be more than 200 PSI but you can do research and check for yourself.

For the Harris regulator I found it has a 5/8 in. - 18 (F) outlet connection
and the nut off of amazon is
Nut: CGA-032 (5/8" - 18) RH Male "B" Size
Which is what you want, and probably why they are frequently bought together.

The Reynolds bag is made of nylon and I have read that the material should be LDPE (low density polyethylene). It seems to me that the bag material and size, especially the width, is important. I have ordered and received four different bags and they all have different thickness material and the actual thickness, as measured with an accurate micrometer is much thinner than the advertised thickness. The thickness, if it's given at all, is usually stated in "mils", where one mil is 1/1000 th of an inch. The bags I have are between one half mil and three mills. I would think that the thickness is important for strength and ability to "scrunch"all the air out. I'd appreciate any comments.

Oh that's a good point about bag's ability to scrunch the air out! Hmm, cause I ordered 4 different types bags too all with different thickness (cause I don't trust the flimsy oven bags). What are you currently using or leaning towards? I just posted my own setup and qus and I have three different bags rn but leaning towards the thickest one, a 18x24 in storage-type ziploc (I'll ignore the zip). It is LDPE (slightly cloudy - the oven/cellophane ones are crystal clear). But yeah the scrunch part…. I may have to use the middle thickness one (shirt packaging thickness) but it has a bad chemical smell :( may have to order yet another type but trying to get this thickness again! (So annoying that they either don't post it or lie about the mils!)
