Help Hose for Nitrogen Method

[how2toGetout]

i was reading TiredHorse's post on 'Exit bag and inert gas megathread' and i didn't really understand the "Hose" part:

The Hose:

The hose needs to be long enough to reach from the gas cylinder beside you, up into the exit bag on your head. I have found it easiest to lead the hose up my back and into the bag at the very back of my neck. It seems to disrupt the fit of the bag less right there.

Some regulators come with a hose that threads directly into the regulator body. Some regulators come with a hose-barb, onto which a length of soft tubing can be pressed. Some regulators come with neither.

For the first situation, just thread the hose into the regulator, tighten it with a wrench, and it's ready.

(Regardless of what type of threaded fitting is used, you do need to wrench-tighten this fitting: a lot of gas can leak out at this connection. If it is a brass fitting, you should not need teflon tape on the threads; the soft metal deforms enough when tightened to provide an adequately gas-tight connection.)

For the second situation, take the hose-barb to a hardware / home improvement store and purchase tubing that fits onto the barb. Once home from the hardware store, thread the barb into the regulator body, tighten with a wrench, and press the tube onto the barb. It should be a snug fit; if you're worried it's too loose, use a small hose clamp / jubilee clip to secure it in place. If it's a little too tight to get the hose into place, soak the end of the tube in very hot water to soften it and press it onto the barb. I used clear vinyl tubing. Aquarium tubing should work. Surgical tubing may not; I don't know for sure.

For the third situation, you'll need a hose-barb fitting (typically brass) that threads into the regulator body. Take the entire regulator to the hardware store and ask someone to help you fit it with a hose barb. Then proceed as for the second situation.

Cover story: as with purchasing the gas cylinder, you're using N2 for brewing, or Ar for filling partial paint cans. Why Ar? because it's heavier than air and settles down onto the paint surface inside the can. For extra confidence that they won't ask inconvenient questions, you're doing it for your father, or your brother, and you don't know why they want it for their paint locker, they just said to get a hose barb and six feet of tubing…

TiredHorse said there are regulators that come with a hose that threads directly into the regulator body:

Does the above kind of hose have a metal knob at the end? SO in the "first situation" case where the regulator comes with a hose, does that mean a separate rubber soft tubing is not needed as a hose?

I just didn't understand 'The Hose' part of the explanation/guide by TiredHorse.

Can anyone help me visualize what the "first situation" is?

Maybe my question was a bit vague..

I meant to ask whether the "hose" in the "first situation" has metal threads/knobs at the end of each side of the hose.

I wanted to put/link an example image here but google images are all products of the hose, so i didn't want to put link here, which may be against the rule to post links of items here in the forum.

I googled for "hose for nitrogen regulator", then went under google image section. Saw bunch of hoses that kinda look like water hoses for gardening except they're thinner in diameter and are mostly colored yellow if made of rubber and sometimes has metallic textures for some of them..

i need some guidance in understanding what a hose would look like.. when attached to a regulator..

Either should work. You can use an appropriately sized PVC hose you can buy at Walmart or Home Depot or wherever, and secure it with a hose clamp, or use one with the metal bit specifically threaded for a nitrogen regulator.

I opted for a length of PVC hosing from Home Depot, instead of spending $100 and waiting on shipping for a proper length hose specifically designed to attach to a nitrogen regulator.

Is this "nitrogen regulator" that you mention, a oxygen regulator in actuality? Or is it really a "real" nitrogen regulator?

It's an argon/CO2 flowmeter, actually.

Okay.. so is argon/CO2 flowmeter actually same as a regulator (for argon/CO2)?

Is the flowmeter the one mentioned by TiredHorse on the 'Exit bag and inert gas megathread'? The one available on Harbor Freight Tools?

A flowmeter measures flowrate, a regulator measures pressure. I'd recommend looking them up online, Amazon has some of both, so you can see product pictures and familiarize yourself with the difference. At the end of the day, they both attach to a compressed gas container and control the flow of gas coming out. The one I got was less than $30 on Amazon.

Can you please PM me the name of the regulator/flowmeter on amazon?

i still have hard time visualizing what a flowmeter is/does, and what a regulator is/does.
i would very much appreciate if you can help me find one of each category to look at on amazon.
