Help Nitrogen regulator

[TitianCashew26]

I'm trying to find a reliable nitrogen flowmeter/regulator for the inert gas method; there are many options online.

What is the best option?

The one I got was the Miller Flow Gauge Regulator https://www.millerwelds.com/accesso...rs/flow-gauge-argon-regulator-50-scfh-3150580 For Argon, meaning you'll have to adjust the flow rate a tad bit higher than 15 lpm to properly equate 15 lpm on an argon regulator.

I couldn't trust any regulator on Amazon because the one I got was cheap and leaked. So I went with one that's more expensive and name brand

Thank you! Did you have any problems with the Miller?

Honestly, finding the

• Nut: CGA-032 (5/8" - 18) RH Male "B" Size
• Nipple: 2-7/32" Length, 1/4" Hose, "B" Size

For the regulator was a bit of a hassle, to warn you.
I live in Canada and found both pieces eventually on Amazon

Depending on your tank, I found I had to tighten it quite a bit so it doesn't leak.

It's a bit costly but I found it on a Canadian website for half the price it goes for.

Other than those few caveats it's a solid regulator that has worked well in all the tests I have done.

@SomewhereAlongThe So, just buying a regulator is not sufficient to connect it to the tank; you have to also buy a nut and nipple?

Buying the regulator is sufficient to connect it to the tank, but if you want to be able to connect a hose you need the barbed nipple. Unfortunately the regulator doesn't come with one.

Understood, thank you!

What continent are you from? The one in the image is a Bossweld, dual gauge reg with built in flow meter. Not expensive and was the same price at a hardware store as on Ebay. Get one that goes up to 25 LPM if using a bag or CF hood.

Did you get the orange hose locally? Au.
Im not sure what to get to extend the eebd hose.this looks better because you can't accidentally crush it and stop the air flow.

Hi Fella, the hose is available at any hardware or welding store. Are you using a hood or a plastic bag? Hood youll want a similar dimension hose; plastic bag use medical transparent thin hose. But you know that right?

 

[mrsmith]

Hi, thanks for replying.
I chose EEBD. (hood).
I like this hose in the pic because it's a continental variflex which apparently COULD be quite flexible and crush resistant too, both qualities ideal for our needs I think.
I actually first thought you were in Aus for some reason and then realised your username, lol.
I bought the bossweld dual stage N regulator as well(I already have a single stage regulator). I read that dual stage reg holds pressure stable better.
Did the hose fit the regulator barb ok?, because the barb is 5mm I think and the hose is about 6.4mm if it matches EEBD hose right?

 

[k1w1]

Thank YOU for replying. I am trying to summon the courage to get this task done this evening. I have taken plenty of relaxants so am rather dreamy. Im just watching some of my favourite documentaries and deciding wether to have a final meal. The hose fits the barb just fine with a hose clamp. The Bosswell is a super regulator....two stage. Ill be online for another couple of hours.

Hello can you use the hose that comes with the regulator or does it have to be oxygen tubing? Thanks

Using oxygen tubing is the standard tubing used for exit bags. I'd recommend sticking with that. Using the tubing that comes with the regulator may present problems, it may be too heavy and cause too big of a gap at the entrance where you put the tube into the bag. I used PVC tubing and I believe it left just a big gap enough to purge the CO2.

How do you connect the oxygen or PVC tubing so that there is no leaks?

You connect the tubing to the nipple on the regulator, and then test to see if there are leaks using a soapy water solution.

Thanks! and how do I connect the other end of the tube to the bag? Or do I tape it to my body/neck?

You tape it to the inside of the bag, near the back of the head or even near the face, you wanna make sure the tubing reaches the top of the bag.

I thought of taping it to my neck since I'm using an oven roasting bag and its very light and cant hold forces with out deforming.

Do you know how to position your head? For example, if I am sitting on the couch, my head will fall back into the cushion when I pass out, or if I am in a recliner, it will be resting back against the back rest. Will this mess up the bag inflation? Or should I just inflate it with my head already leaning back? Also am wondering how tight to tighten the bag around the neck? A firm fit, a somewhat loose fit, or as tight as it goes? Thanks for the help.

Edit: Also wondering what oxygen meter(s) to get?

I was thinking of sitting in the car with the seat tilted a bit to the back and seat belt fastened. That should reduce risk of things going wrong when I start involuntary movements.
About the tightness, The PPH recommends a fit that allows a few fingers to be inserted between the neck and the bag. It described as tight but not choking.
