Help Help with gas cylinder regulator

[Obliviate]

So I bought my Argon gas cylinder and a regulator/flowmeter. But when I turn my valve on, it is really loud and seems like it may be leaking. All the wrenches I have are too small but I tightened it as much as I could. The flow meter is closed as well. I have attached a video if someone can help. I put my hand on the main exit valve and can feel the gas.

You really need to tighten it with a wrench. At the pressure that the gas cylinder is providing (~2000psi), hand-tight just won't do it. Even a cheap adjustable wrench will do the job. It doesn't need to be superman tight, but does need to be tighter than you can get it just by hand. "Snug" would be a good description, I think.

I have so many wrenches at home but neither have them are the huge ones which I think I'm gonna need to tighten it. So from the video the gas is leaking right? It's way too loud

You need to come up with the right wrench and tighten the fitting appropriately. You can make a wrench, too, out of a flat piece of metal and a hacksaw. You could even hoseclamp a small wrench or flat piece of metal against one of the flats on the nut and get the nut to turn a little more than only by your hand.

It worked! Now I'm happy again
